Description

Die vorliegende Erfindung betrifft eine mobile Druckluftgeräteeinheit nach dem Oberbegriff des Anspruchs 1.The present invention relates to a mobile compressed air device unit according to the preamble of claim 1.

Eine gattungsgemäße mobile Druckluftgeräteeinheit ist aus der US 6,932,128 B2 bekannt, die ein druckluftbetriebenes Arbeitsgerät betrifft, das über eine flexible Schlauchverbindung mit einer mit einem Tragegurt versehenen Druckluftspeichereinheit verbunden ist.A generic mobile compressed air device unit is from the US 6,932,128 B2 known, which relates to a compressed air-operated working device which is connected via a flexible hose connection to a compressed air storage unit provided with a carrying strap.

Die bekannte mobile Druckluftgeräteeinheit bietet zwar den Vorteil, dass das druckluftbetriebene Arbeitsgerät unabhängig von einem Netzanschluss über die angeschlossene Druckluftspeichereinheit betrieben werden kann. Jedoch ist es für den Einsatz des Arbeitsgerätes erforderlich, dass die Speichereinheit am Körper der das Arbeitsgerät handhabende Bedienperson getragen wird.The known mobile compressed air device unit offers the advantage that the compressed air operated work device can be operated independently of a mains connection via the connected compressed air storage unit. However, for the use of the implement it is necessary that the storage unit is carried on the body of the operator handling the implement.

Weiterhin ist bezogen auf den Standort der Bedienungsperson der Aktionsradius oder Handhabungsradius des Arbeitsgerätes durch die Länge der Schlauchverbindung begrenzt. Hierdurch ist es beispielsweise nicht möglich, das Arbeitsgerät von einer Bedienperson an eine weitere Bedienperson zu übergeben, ohne dass eine entsprechende Übergabe der über den Tragegurt an der ersten Bedienperson fixierten Druckluftspeichereinheit erfolgt. Damit ist in der Praxis die Handhabung des Arbeitsgerätes durch eine Mehrzahl von Bedienpersonen kaum möglich.Furthermore, based on the location of the operator, the radius of action or handling radius of the implement is limited by the length of the hose connection. As a result, it is not possible, for example, to transfer the work device from one operator to another operator to be transferred without a corresponding transfer of the compressed air storage unit fixed to the first operator via the carrying strap. This means that in practice it is hardly possible for a plurality of operators to handle the implement.

Die US 2005/252944 A1 offenbart eine mobile Druckluftgeräteeinheit mit einer unterhalb einer Druckluftspeichereinheit angeordneten Magazineinrichtung.the US 2005/252944 A1 discloses a mobile compressed air device unit with a magazine device arranged below a compressed air storage unit.

Die US 2013/1755313 A1 sowie die JP 2002 059374 A beschreiben jeweils eine mobile Druckluftgeräteeinheit mit einer seitlich einer Druckluftspeichereinheit angeordneten Magazineinrichtung.the US 2013/1755313 A1 as well as the JP 2002 059374 A each describe a mobile compressed air device unit with a magazine device arranged on the side of a compressed air storage unit.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine mobile Druckluftgeräteeinheit vorzuschlagen, die eine einfache Handhabung der Druckluftgeräteeinheit von mehreren Bedienpersonen ermöglicht.The present invention is therefore based on the object of proposing a mobile compressed air device unit which enables the compressed air device unit to be easily handled by several operators.

Zur Lösung dieser Aufgabe weist die erfindungsgemäße mobile Druckluftgeräteeinheit die Merkmale des Anspruchs 1 auf.To achieve this object, the mobile compressed air device unit according to the invention has the features of claim 1.

Bei der erfindungsgemäßen mobilen Druckluftgeräteeinheit ist die Druckluftverbindung als Trägereinrichtung zur schlauchlosen Verbindung des Arbeitsgerätes mit der Druckluftspeichereinheit in einer definierten Relativanordnung und Ausbildung der Druckluftgeräteeinheit als Handhabungseinheit ausgebildet.In the mobile compressed air device unit according to the invention, the compressed air connection is designed as a carrier device for the hose-free connection of the working device to the compressed air storage unit in a defined relative arrangement and the compressed air device unit is designed as a handling unit.

Abweichend von der bekannten mobilen Druckluftgeräteeinheit ist kein an der Bedienperson angeordneter Tragegurt erforderlich, um die Handhabung eines durch eine Schlauchverbindung mit der Druckluftspeichereinheit verbundenen Arbeitsgerätes zu ermöglichen. Vielmehr dient die Druckluftverbindung selbst als Trägereinrichtung zur mechanischen Verbindung des Arbeitsgerätes mit der Druckluftspeichereinheit. Somit ermöglicht die als Trägereinrichtung ausgebildete Druckluftverbindung eine schlauchlose Verbindung zwischen der Druckluftspeichereinheit und dem Arbeitsgerät, wobei die Trägereinrichtung gleichzeitig eine Handhabung des Arbeitsgerätes zusammen mit der daran angeschlossenen Druckluftspeichereinheit als Handhabungseinheit ermöglicht.In contrast to the known mobile compressed air device unit, a carrying strap arranged on the operator is not required in order to enable the handling of a working device connected to the compressed air storage unit by a hose connection. Rather, the compressed air connection itself serves as a carrier device for the mechanical connection of the working device to the compressed air storage unit. The compressed air connection designed as a carrier device thus enables a hose-free connection between the compressed air storage unit and the working device, the carrier device simultaneously enabling the working device to be handled together with the compressed air storage unit connected to it as a handling unit.

Im Unterschied zu der bekannten mobilen Druckluftgeräteeinheit kann somit ohne Weiteres eine Nutzung der erfindungsgemäßen mobilen Druckluftgeräteeinheit durch mehrere Bedienpersonen durch einfache Übergabe der Handhabungseinheit von einer Bedienperson an die nächste Bedienperson erfolgen, ohne dass hierzu besondere Maßnahmen erforderlich wären.In contrast to the known mobile compressed air device unit, the mobile compressed air device unit according to the invention can easily be used by several operators by simply handing over the handling unit from one operator to the next, without special measures being required.

Durch die Ausbildung der Druckluftverbindung als Trägereinrichtung kann dabei die Übergabe beispielsweise derart erfolgen, dass das Arbeitsgerät noch von der ersten Person gehalten wird, während die nächste Bedienperson zur Übernahme die Trägereinrichtung mit der einen Hand erfasst, um zur Bedienung des Arbeitsgerätes die Handhabungseinheit an die andere Hand zu übergeben und hierzu den Handgriff des Arbeitsgerätes umgreift.By designing the compressed air connection as a carrier device, the handover can take place, for example, in such a way that the work device is still held by the first person while the next operator grabs the carrier device with one hand to operate the work device in order to operate the work device Hand to hand and for this purpose grasps the handle of the implement.

Hierzu kann es sich als besonders vorteilhaft erweisen, wenn die als Druckluftverbindung ausgebildete Trägereinrichtung eine Ausgestaltung als Handgriff aufweist.For this purpose, it can prove to be particularly advantageous if the carrier device designed as a compressed air connection has a design as a handle.

Erfindungsgemäß ist die Druckluftverbindung als Druckluftmindereinheit mit einem Druckluftspeicheranschluss und einem Druckluftgeräteanschluss ausgebildet, die auf einer Anschlussseite eines Gehäuses der Druckluftmindereinheit angeordnet sind. Somit ist es möglich, dass bei der Handhabungseinheit der Druckluftspeicher und das Arbeitsgerät sich von einer gemeinsamen Gehäuseseite weg erstrecken, sodass eine kompakte Ausbildung der Handhabungseinheit möglich wird.According to the invention, the compressed air connection is designed as a compressed air reducer unit with a compressed air storage connection and a compressed air device connection, which are arranged on a connection side of a housing of the compressed air reducer unit. It is thus possible for the compressed air reservoir and the working device in the handling unit to extend away from a common housing side, so that a compact design of the handling unit is possible.

Dadurch, dass der Druckluftspeicheranschluss und der Druckluftgeräteanschluss erfindungsgemäß parallele Anschlussachsen aufweisen, wird eine besonders kompakte Ausgestaltung der Handhabungseinheit möglich.Because the compressed air storage connection and the compressed air device connection have parallel connection axes according to the invention a particularly compact design of the handling unit is possible.

Erfindungsgemäß sind dabei die Anschlussachsen senkrecht zur Anschlussseite angeordnet.According to the invention, the connection axes are arranged perpendicular to the connection side.

Erfindergemäß weisen weiterhin die Anschlussachsen einen Achsenabstand voneinander aufweisen, der dem Achsenabstand einer Längsachse eines sich koaxial zum Druckluftgeräteanschluss erstreckenden Handgriffteils des angeschlossenen Arbeitsgerätes zu einer Längsachse einer sich im Wesentlichen parallel zum Handgriffteil erstreckenden Magazineinrichtung des Arbeitsgerätes entspricht, kann eine zu einer Magazineinrichtung im Wesentlichen parallele Anordnung der Druckluftspeichereinheit am Arbeitsgerät erfolgen.According to the invention, the connection axes furthermore have an axial spacing from one another which corresponds to the axial spacing of a longitudinal axis of a handle part of the connected tool that extends coaxially to the compressed air device connection to a longitudinal axis of a magazine device of the tool that extends essentially parallel to the handle part, an arrangement that is essentially parallel to a magazine device the compressed air storage unit on the work device.

Vorzugsweise ist der Druckluftgeräteanschluss der Druckluftverbindung derart ausgebildet, dass zwischen dem Arbeitsgerät und der mittels des Druckluftgeräteanschlusses mit dem Arbeitsgerät verbundenen Druckluftverbindung eine Relativdrehung um die Anschlussachse des Druckluftgeräteanschlusses möglich ist, sodass etwa ein Umschwenken der Druckluftspeichereinheit aus einer zu einer linken Längsseite der Magazineinrichtung parallelen Anordnung in eine zu einer rechten Längsseite der Magazineinrichtung parallelen Anordnung möglich ist. Dies erweist sich insbesondere bei der Handhabung beziehungsweise dem Einsatz des Arbeitsgerätes in Raumecken als vorteilhaft, wo das Arbeitsgerät in einer zu einer Raumwand möglichst benachbarten Anordnung eingesetzt werden soll, ohne dass die Druckluftspeichereinheit zwischen der Raumwand und dem Arbeitsgerät angeordnet ist.The compressed air device connection of the compressed air connection is preferably designed in such a way that a relative rotation about the connection axis of the compressed air device connection is possible between the work device and the compressed air connection connected to the work device by means of the compressed air device connection, so that, for example, the compressed air storage unit can be pivoted from an arrangement parallel to a left longitudinal side of the magazine device in an arrangement parallel to a right long side of the magazine device is possible. This proves to be particularly advantageous when handling or using the tool in corners of a room, where the tool is to be used in an arrangement as close as possible to a room wall without the compressed air storage unit being arranged between the room wall and the tool.

Die Druckluftmindereinheit ist zur Ausbildung einer Druckluftverbindung zwischen einem mit Druckluft betriebenen Arbeitsgerät und einer Druckluftspeichereinheit als Verbindungskonsole zur mechanischen Verbindung des Arbeitsgerätes mit der Druckluftspeichereinheit und Ausbildung einer das Arbeitsgerät und die Druckluftspeichereinheit umfassenden, eine Handhabungseinheit bildenden Druckluftgeräteeinheit nach Anspruch 1 ausgeführt. Vorzugsweise weist die Druckluftmindereinheit ein Gehäuse auf mit zwei in einer gemeinsamen Gehäuseebene zueinander versetzt angeordneten und in einem Gehäusemittelteil miteinander verbundenen Gehäuseschenkeln, die auf einer Anschlussseite des Gehäuses jeweils an ihrem freien Ende ein Druckluftgeräteanschluss und einen Druckluftspeicheranschluss mit zueinander parallele Anschlussachsen aufweisen, derart, dass in dem einen Gehäuseschenkel der Druckluftspeicheranschluss und in dem anderen Gehäuseschenkel der Druckluftgeräteanschluss angeordnet ist. Hierdurch wird eine besonders kompakte Ausgestaltung des Gehäuses mit einem möglichst kleinen Gehäusevolumen möglich, bei der die größte Längserstreckung des Gehäuses im Wesentlichen durch den Achsabstand der Anschlussachsen gegeben ist.The compressed air reduction unit is to form a compressed air connection between a work device operated with compressed air and a compressed air storage unit as a connection console for the mechanical connection of the Work device with the compressed air storage unit and the formation of a compressed air device unit comprising the work device and the compressed air storage unit and forming a handling unit according to claim 1. The compressed air reducer unit preferably has a housing with two housing legs which are offset from one another in a common housing plane and are connected to one another in a central housing part, each having a compressed air device connection and a compressed air storage connection with parallel connection axes on a connection side of the housing at their free end, such that in the compressed air storage connection is arranged in one housing leg and the compressed air device connection is arranged in the other housing leg. This enables a particularly compact design of the housing with the smallest possible housing volume, in which the greatest longitudinal extent of the housing is essentially given by the center distance of the connection axes.

Weiterhin sind vorzugsweise in dem Gehäusemittelteil eine Druckluftmindereinrichtung und ein Sicherheitsventil angeordnet.Furthermore, a compressed air reducing device and a safety valve are preferably arranged in the middle part of the housing.

Nachfolgend werden weitere Ausführungsformen der Erfindung anhand der Zeichnungen näher erläutert.Further embodiments of the invention are explained in more detail below with reference to the drawings.

In den Fig. 1 bis 3 ist eine mobile Druckluftgeräteeinheit 10, umfassend ein druckluftbetriebenes Arbeitsgerät 11, eine Druckluftspeichereinheit 12 sowie eine als Druckluftmindereinheit 30 ausgebildete Druckluftverbindung 13, in unterschiedlichen Konfigurationen dargestellt.In the Figs. 1 to 3 A mobile compressed air device unit 10, comprising a compressed air-operated working device 11, a compressed air storage unit 12 and a compressed air connection 13 designed as a compressed air reducing unit 30, is shown in different configurations.

Wie insbesondere Fig. 4 zeigt, weist die Druckluftverbindung 13 ein Druckluftgehäuse 14 auf, das auf einer Anschlussseite 15 mit einem hier als Schnellkupplung ausgeführten Druckluftgeräteanschluss 16 sowie einem Druckluftspeicheranschluss 17 zur Verbindung mit der hier als Kartusche ausgeführten Druckluftspeichereinheit 12 versehen ist. Das Arbeitsgerät 11 sowie die Druckluftspeichereinheit 12 sind mit geeigneten Gegenanschlüssen 18 beziehungsweise 19 versehen, die im Falle des Gegenanschlusses 18 eine verrastende Aufnahme in dem Druckluftgeräteanschluss 16 sowie im Falle des Gegenanschlusses 19 eine Schraubverbindung mit dem Druckluftspeicheranschluss 17 ermöglichen.How in particular Fig. 4 shows, the compressed air connection 13 has a compressed air housing 14, which is provided on a connection side 15 with a compressed air device connection 16 designed here as a quick coupling and a compressed air storage connection 17 for connection to the compressed air storage unit 12 designed here as a cartridge. The working device 11 and the compressed air storage unit 12 are provided with suitable mating connections 18 and 19, respectively, which, in the case of the mating connection 18, enable a locking receptacle in the compressed air device connection 16 and, in the case of the mating connection 19, a screw connection to the compressed air storage connection 17.

Wie am besten in Fig. 2 zu erkennen ist, ist das Arbeitsgerät 11 im vorliegenden Fall beispielhaft als Druckluftnagler ausgebildet, der an einem axialen Ende eines Handgriffteils 20 eine Treibkolbeneinheit 21 mit einem Aufsatzmundstück 22 aufweist, das zur Ausgabe in einer Magazineinrichtung 23, die sich parallel zum Handgriffteil 20 erstreckt, bevorrateter Befestigungsmitteln, wie etwa Nägeln, dient, die bei Betätigung einer am Handgriffteil 20 angeordneten Auslösevorrichtung 24 aus einem Austreibkanal des Aufsatzmundstückes 22 ausgetrieben und in eine mit dem Aufsatzmundstück 22 in Kontakt stehende Oberfläche eingetrieben werden.As best in Fig. 2 As can be seen, the working device 11 in the present case is designed, for example, as a compressed air nailer which has a drive piston unit 21 at one axial end of a handle part 20 with an attachment mouthpiece 22, which serves to dispense stored fastening means, such as nails, in a magazine device 23, which extends parallel to the handle part 20, which when a triggering device 24 arranged on the handle part 20 is actuated from an expulsion channel of the attachment mouthpiece 22 and in a surface which is in contact with the attachment mouthpiece 22 can be driven in.

Grundsätzlich ist jedoch die Flexibilität der Druckluftgeräteeinheit hervorzuheben, so dass zur Ausbildung der durch den Anspruch 1 definierten und hier lediglich in einem Ausführungsbeispiel dargestellten Druckluftgeräteeinheit etwa auch eine Kombination der Druckluftspeichereinheit mit einem als Druckluftschleifer oder als Druckluftbohrer ausgebildeten Arbeitsgerät möglich ist.Basically, however, the flexibility of the compressed air device unit is to be emphasized, so that a combination of the compressed air storage unit with a working device designed as a compressed air grinder or a compressed air drill is possible to form the compressed air device unit defined by claim 1 and shown here only in one embodiment.

Wie aus der Abfolge der Fig. 1 bis 3 deutlich wird, kann die Druckluftspeichereinheit 12 in ihrer Relativanordnung zu dem Arbeitsgerät 11 dadurch verändert werden, dass die Druckluftverbindung 13 zusammen mit der daran angeschlossenen Druckluftspeichereinheit 12 um eine Anschlussachse 25 des Druckluftgeräteanschluss 16 verschwenkt und somit etwa von der in Fig. 1 dargestellten rechtsseitigen Position, in der sich die Druckluftspeichereinheit 12 im Wesentlich parallel zu einer rechten Längsseite 26 der Magazineinrichtung 23 befindet, in eine linksseitige Position verschwenkt werden kann, in der sich die Druckluftspeichereinheit 12 im Wesentlichen parallel zu einer linken Längsseite 27 der Magazineinrichtung 23 befindet.As from the sequence of Figs. 1 to 3 becomes clear, the arrangement of the compressed air storage unit 12 relative to the working device 11 can be changed by pivoting the compressed air connection 13 together with the compressed air storage unit 12 connected to it about a connection axis 25 of the compressed air device connection 16 and thus approximately from the in Fig. 1 right-hand position shown, in which the compressed air storage unit 12 is essentially parallel to a right longitudinal side 26 of the magazine device 23, can be pivoted into a left-hand position in which the compressed air storage unit 12 is essentially parallel to a left longitudinal side 27 of the magazine device 23.

Wie aus den Fig. 1 bis 4 deutlich wird, sind die Anschlussachse 25 des Druckluftgeräteanschlusses 16 und eine Anschlussachse 28 des Druckluftspeicheranschlusses 17 parallel zueinander angeordnet und weisen einen Achsenabstand a auf, der im Wesentlichen dem Abstand b einer Längsachse 29 des Handgriffteils 20 von einer Längsachse 31 der Magazineinrichtung 23 entspricht, derart, dass sich in der in Fig. 1 dargestellten rechtsseitigen Position der Druckluftspeichereinheit 12 sowie der in Fig. 3 dargestellten linksseitigen Position der Druckluftspeichereinheit 12 sich letztere nicht nur in einer zur Magazineinrichtung 23 parallelen Anordnung, sondern darüber hinaus auch in einer die Magazineinrichtung 23 überdeckenden Anordnung befindet, also weder das Arbeitsgerät 11 über die Magazineinrichtung 23 hinaus nach unten überragt noch einen Eingriff einer der den Handgriffteil 20 erfassenden Hand einer Bedienperson in einen zwischen dem Handgriffteil 20 und der Magazineinrichtung 23 ausgebildeten Durchgriffsraum D behindert.As from the Figs. 1 to 4 As becomes clear, the connection axis 25 of the compressed air device connection 16 and a connection axis 28 of the compressed air storage connection 17 are arranged parallel to one another and have an axis distance a, which corresponds essentially to the distance b of a longitudinal axis 29 of the handle part 20 from a longitudinal axis 31 of the magazine device 23, such as that in the in Fig. 1 The position of the compressed air storage unit 12 shown on the right as well as the position shown in FIG Fig. 3 The position of the compressed air storage unit 12 shown on the left-hand side is located not only in an arrangement parallel to the magazine device 23, but also in an arrangement that overlaps the magazine device 23, i.e. neither the working device 11 protrudes beyond the magazine device 23 downward, nor an engagement of one of the Handgrip part 20 grasping hand of an operator into a passage space D formed between the handle part 20 and the magazine device 23.

Wie insbesondere aus einer Zusammenschau der Fig. 1 und 4 ersichtlich, bildet die Druckluftverbindung 13 eine lösbare mechanischen Verbindungskonsole zwischen dem Arbeitsgerät 11 und der Druckluftspeichereinheit 12, wobei die Verbindungskonsole die Ausbildung einer das Arbeitsgerät 11 und die Druckluftspeichereinheit 12 umfassenden Handhabungseinheit ermöglicht, wobei insbesondere bei einer Übergabe der als Handhabungseinheit ausgebildeten Druckluftgeräteeinheit 10 von einer Bedienperson an eine andere Bedienperson die Druckluftgeräteeinheit 10 von der anderen Bedienperson durch Ergreifen der Verbindungskonsole übernommen werden kann.As in particular from a synopsis of the Fig. 1 and 4th As can be seen, the compressed air connection 13 forms a detachable mechanical connection console between the work device 11 and the compressed air storage unit 12, the connection console enabling the formation of a handling unit comprising the work device 11 and the compressed air storage unit 12, in particular when the compressed air device unit 10 designed as a handling unit is handed over by an operator to another operator, the compressed air device unit 10 can be taken over by the other operator by grasping the connection console.

Wie im Nachfolgenden unter Bezugnahme auf die Fig. 5 bis 8 noch näher ausgeführt wird, ist die Druckluftverbindung 13 im vorliegenden Fall nicht nur als Verbindungskonsole ausgebildet, sondern bildet gleichzeitig auch eine Druckluftmindereinheit 30 in dem Druckluftgehäuse 14 aus, das neben dem Druckluftarbeitsgeräteanschluss 16 und dem Druckluftspeicheranschluss 17 eine Druckluftmindereinrichtung 32 aufweist. Wie Fig. 7 zeigt, befindet sich die Druckluftmindereinrichtung 32 in einem Gehäusemittelteil 33, wohingegen der Druckluftgeräteanschluss 16 und der Druckluftspeicheranschluss 17 jeweils am freien Ende eines Gehäuseschenkels 34 beziehungsweise Gehäuseschenkels 35 angeordnet sind, die sich in entgegengesetzte Richtungen vom Gehäusemittelteil 33 weg erstrecken und in einer gemeinsamen Gehäuseebene angeordnet sind. Wie aus einer Zusammenschau der Fig. 6 und 7 ersichtlich ist, ist der Druckluftspeicheranschluss 17, der zur Verbindung mit der in den Fig. 1 bis 4 dargestellten, hier als Kartusche ausgeführten Druckluftspeichereinheit 12 dient, über eine Speicherluftleitung 37 mit einem Druckluftzugang 38 der Druckluftmindereinrichtung 32 und der Druckluftgeräteanschluss 16 über eine Arbeitsluftleitung 39 mit einem Druckluftausgang 40 der Druckluftmindereinrichtung 32 verbunden. Die Druckluftmindereinrichtung 32 ist auf eine definierte Druckdifferenz eingestellt, derart, dass beispielsweise eine Speicherluft mit 300 bar am Druckluftzugang 38 auf einen Arbeitsluftdruck von 6,5 bar am Druckluftausgang 40 reduziert wird. Natürlich sind durch geeignete Auswahl für eine in der Druckluftmindereinrichtung 32 angeordnete Schließfeder 41 und eine Einstellfeder 42 bei Bedarf abweichende Druckdifferenzen einstellbar.As in the following with reference to the Figures 5 to 8 In the present case, the compressed air connection 13 is not only designed as a connection bracket, but also simultaneously forms a compressed air reducing unit 30 in the compressed air housing 14, which has a compressed air reducing device 32 in addition to the compressed air working device connection 16 and the compressed air storage connection 17. As Fig. 7 shows, the compressed air reducing device 32 is located in a housing middle part 33, whereas the compressed air device connection 16 and the compressed air storage connection 17 are each arranged at the free end of a housing leg 34 and housing leg 35, respectively, which extend in opposite directions away from the housing middle part 33 and are arranged in a common housing plane . As if from a synopsis of the Figures 6 and 7 As can be seen, the compressed air storage connection 17, which is used for connection with the in the Figs. 1 to 4 The compressed air storage unit 12 shown here, designed as a cartridge, is connected via a storage air line 37 to a compressed air inlet 38 of the compressed air reducing device 32 and the compressed air device connection 16 is connected via a working air line 39 to a compressed air outlet 40 of the compressed air reducing device 32. The compressed air reducing device 32 is set to a defined pressure difference such that, for example, a storage air with 300 bar at the compressed air inlet 38 is reduced to a working air pressure of 6.5 bar at the compressed air outlet 40. Of course, by suitable selection for a closing spring 41 arranged in the compressed air reducing device 32 and an adjusting spring 42, deviating pressure differences can be set if necessary.

Wie insbesondere aus Fig. 7 zu ersehen, ist im vorliegenden Fall die Speicherluftleitung 37 mit einem Manometer 43 zur Anzeige des Fülldrucks der Druckluftspeichereinheit 12 vorgesehen. In der Arbeitsluftleitung 39 ist parallel zum Druckluftgeräteanschluss 16 ein Sicherheitsventil 44 vorgesehen, das bei einem Versagen der Druckluftmindereinrichtung 32 eine Druckluftüberlast des Arbeitsgerätes 11 verhindert.Like in particular from Fig. 7 As can be seen, in the present case the storage air line 37 is provided with a manometer 43 for displaying the filling pressure of the compressed air storage unit 12. A safety valve 44 is provided in the working air line 39 parallel to the compressed air device connection 16, which valve prevents the working device 11 from being overloaded with compressed air in the event of a failure of the compressed air reducing device 32.
