Description
Saugplatte 1 der Hochdruck-Kolbenpumpe 30 einströmt. Suction plate 1 of the high pressure piston pump 30 flows in.
Das Wasser wird also in Pfeilrichtung 29 wieder der Kolbenpumpe zugeführt, so daß eine Überlastung der Hochdruckpumpe 30 vermieden wird.The water is thus fed back to the piston pump in the direction of arrow 29, so that the High pressure pump 30 is avoided.
Die Kraft der Druckfeder 8 kann dadurch eingestellt werden, daß das Gehäuse 7, in dem die Druckfeder 8 gelagert ist, über ein Gewinde und eine Dichtung 9 an einem Regtlventilkörper 36 des RegeJvenüls ansetzt Durch Verdrehen des Gehäuses 7 in Bezug zum Regelventilkörper 36 wird dann die Kraft der Druckfeder 8 eingestelltThe force of the compression spring 8 can be adjusted in that the housing 7, in which the compression spring 8 is mounted, via a thread and a seal 9 a Regtlventilkörper 36 of the RegeJvenül attaches By rotating the housing 7 in relation to the control valve body 36, the force of the compression spring 8 is then increased set
In besonders einfacher Weise ist zu dem Oberströmventil 4 eine zusätzliche Druck-Mengenreguliervorrichtung vorgesehen. Diese besteht aus einem Druck-Mengenregulierventil 35, das im Bypass zur druckseitigen Rücklauf bohrung 13 angeordnet istThe overflow valve is particularly simple 4 an additional pressure-volume regulating device is provided. This consists of a pressure volume control valve 35, which is arranged in the bypass to the pressure-side return bore 13
Die Eingangsseite des Druck-Mengenregulierventils 35 zweigt dabei von der druckseitigen Rücklaufbohrung 13 ab, wobei der Querschnitt durch eine kegelige Spindel 15, die drehfest mit der Drosselschraube 3 verbunden ist veränderbar istThe inlet side of the pressure volume control valve 35 branches off from the pressure-side return bore 13, the cross section through a conical spindle 15, which is non-rotatably connected to the throttle screw 3, can be changed
Die Ausgangsseite des Druck-Mengenregulierventils 35 mündet über eine Überströmbohrung 14 in den Ventilraum 34 des Oberströmventils 4. Durch Verändern des Querschnittes der Überströmbohrung 14 durch Einstellung der Spindel 15 wird hierdurch ein Bypass zu dem Überströmventil 4 geschaffen, so daß beispielsweise bei öffnen der Überströmbohrung 14 der Druck and die Menge des Waschwassers verringert wird, während bei vollständig geschlossener Überströmbohrung 14 der Druck und die Menge des von der Hochdruckpumpe 30 ausgestoßenen Waschmediums der Pumpenleistung entsprichtThe output side of the pressure / quantity regulating valve 35 opens into the valve chamber via an overflow bore 14 34 of the overflow valve 4. By changing the cross section of the overflow hole 14 by setting the spindle 15 is thereby created a bypass to the overflow valve 4, so that, for example when opening the overflow hole 14, the pressure and the amount of wash water is reduced while When the overflow hole 14 is completely closed, the pressure and the quantity of the high pressure pump 30 ejected washing medium corresponds to the pump performance
Von besonderem Vorteil ist daß an das Regelventil über den Kanal 18 gleichzeitig ein Druckspeicher 19 und ein Manometer 22 angebaut sind, so daß eine Ablesung der Druckwerte vom Armaturenbrett der Waschanlage her möglich ist wobei gleichzeitig nit der Drosselschraube 3 eine Veränderung der Fördermenge erreicht werden kann. Der Druckspeicher 19 setzt hierbei über einem Kanal 17 an dem Kanal 18 an.It is particularly advantageous that a pressure accumulator 19 and at the same time to the control valve via the channel 18 a pressure gauge 22 are attached so that a reading of the pressure values from the dashboard of the washer forth is possible with a change in the delivery rate achieved at the same time with the throttle screw 3 can be. The pressure accumulator 19 is attached to the channel 18 via a channel 17.
Die Durchlaufbohrungen 11 in dem Kolben 5 des Überströmventils 4 sind so abgestimmt, daß ein selbsttätiges Offnen und Schließen unmöglich ist Bei Druckabfall im Überströmventil 4 wird der Ventilkolben 5 mittels der Druckfeder 8 auf den Ventilsitz gedrückt Dadurch schließt das Überströmventil 4.The through bores 11 in the piston 5 of the overflow valve 4 are coordinated so that an automatic Opening and closing is impossible the compression spring 8 is pressed onto the valve seat as a result of which the overflow valve 4 closes.
Die besonderen Vorteile der vorliegenden Erfindung liegen in der kompakten Bauweise und in der leichten Montierbarkeit der Anordnung an eine herkömmliche Hochdruckpumpe 30, weil das gezeigte Regelventil anstelle der Saug- und Druckventile der Hochdruckpumpe angebaut wird. Durch die Verwendung des Druckspeichers 19 und eines Manometers 22, die direkt über entsprechende Kanäle an dem Regelventil ansetzen, werden zusätzliche Leitungen vermieden. Der Umschaltdruck des Überströmventils ist leicht einstellbar; die Druckfeder 8 wird bei gewünschtem Umschaltdruck mit Stellschraube vorgespannt und dann gekontertThe particular advantages of the present invention are its compact design and its light weight The assembly can be mounted on a conventional high-pressure pump 30 because the control valve shown is in place the suction and pressure valves of the high pressure pump is attached. By using the pressure accumulator 19 and a pressure gauge 22, which attach directly to the control valve via corresponding channels additional lines avoided. The switching pressure of the overflow valve is easily adjustable; the When the switching pressure is required, compression spring 8 is pretensioned with an adjusting screw and then locked
