Die Erfindung betrifft eine Ventilanordnung, insbesonde re Elektromagnetventilanordnung für schlupfgeregelte Kraftfahrzeugbremsanlagen nach dem Oberbegriff des An spruchs 1.The invention relates to a valve arrangement, in particular re solenoid valve arrangement for slip-controlled Motor vehicle brake systems according to the preamble of the An saying 1.
Aus der deutschen Patentanmeldung P 41 35 232.7 ist be reits eine Ventilanordnung gleicher Gattung bekannt ge worden, die mittels einer Parallelschaltung eines Kugel rückschlagventils zu einem weiteren elektromagnetisch ansteuerbaren Ventilschließglied eine direkte Druckmit telverbindung zwischen einem am Druckmittelverbraucher angeschlossenen Druckmittelkanal und einem weiteren, an der Druckmittelquelle angeschlossenen Druckmittelkanal herstellt, sobald der hydraulische Öffnungsdruck des Rückschlagventils den Schließdruck überschreitet. Beide Ventilschließglieder sind räumlich voneinander getrennt, so daß hinsichtlich der Konstruktion und der Montage Nachteile entstehen.From German patent application P 41 35 232.7 be already known a valve assembly of the same genus been made by connecting a ball in parallel check valve to another electromagnetic controllable valve closing member with a direct pressure tel connection between one at the pressure medium consumer connected pressure medium channel and another the pressure medium channel connected to the pressure medium source as soon as the hydraulic opening pressure of the Check valve exceeds the closing pressure. Both Valve closing elements are spatially separated from one another, so that in terms of construction and assembly Disadvantages arise.
Daher ist es die Aufgabe der Erfindung, eine möglichst kompakt bauende Ventilanordnung vorzusehen, die eine einfache Herstellung und Montage der Ventile bei unein geschränkter Gewährleistung der Funktionssicherheit er möglicht. It is therefore the object of the invention, one as possible to provide a compact valve arrangement, the one easy manufacture and assembly of the valves at disagree limited guarantee of functional safety possible.
Diese Aufgabe wird erfindungsgemäß durch die den Patent anspruch 1 kennzeichnenden Merkmale gelöst, wonach die im Ventilgehäuse angeordnete Ventilaufnahmebohrung unab hängig voneinander betätigbare Ventilschließglieder auf weist. Es genügt somit eine Ventilaufnahmebohrung ohne das Erfordernis zur Herstellung zusätzlicher Querbohrun gen und Kanäle.This object is achieved by the patent Claim 1 characteristic features solved, according to which Valve mounting hole in the valve housing independent valve actuators that can be actuated independently of one another points. A valve mounting hole without is therefore sufficient the need to make additional cross holes channels and channels.
Durch die in den Unteransprüchen aufgezeigten Maßnahmen sind zweckmäßige Ausbildungen der Erfindung angegeben, die im Zusammenhang mit den weiteren Merkmalen und Vor teilen der Erfindung nachfolgend anhand mehrerer Zeich nungen näher dargestellt und erläutert werden.By the measures indicated in the subclaims expedient developments of the invention are specified, those related to the other features and pre share the invention below using several characters are shown and explained in more detail.
Es zeigen:Show it:
Fig. 1 eine Draufsicht auf den das erste Ventil schließglied aufweisenden Ventilaufnahmekörper, Fig. 1 is a plan view of the first valve closing member having valve-receiving body,
Fig. 2 einen Querschnitt der Ventilanordnung an der Schnittstelle A-B nach Fig. 1, Fig. 2 shows a cross-section of the valve arrangement at the interface AB according to FIG. 1,
Fig. 3 eine alternative Ausführungsform zur Anordnung des ersten Ventilschließgliedes im Ventilauf nahmekörper des weiteren Ventilschließgliedes. Fig. 3 shows an alternative embodiment for the arrangement of the first valve closing member in the valve receiving body of the further valve closing member.
Es zeigt die Fig. 1 das erste Ventilschließglied 4 außermittig im Ventilaufnahmekörper 5 angeordnet und den zentralen Druckmitteldurchlaß 11 für das weitere Ventil schließglied 3. Das als Rückschlagventil wirksame erste Ventilschließglied 4 ist als Kugelventil ausgeführt. Der Ventilaufnahmekörper 5 ist eine scheibenförmige Ventil platte, die der Ventilaufnahmebohrung des Ventilgehäuses angepaßt ist (vergleiche Fig. 3). There is shown in FIG. 1, the first valve closing member 4 eccentrically in the valve accommodating body 5 is arranged and the central fluid passage 11 for the further valve closing element 3. The first valve closing element 4 , which acts as a check valve, is designed as a ball valve. The valve receiving body 5 is a disc-shaped valve plate which is adapted to the valve receiving bore of the valve housing (see Fig. 3).
Die Fig. 2 zeigt einen Querschnitt in der aus Fig. 1 ersichtlichen Ebene des ersten Ventilschließgliedes 4. Der erste wie auch der weitere Ventilaufnahmekörper 5, 6 sind in Überdeckung derart angeordnet, daß die Druckmit teldurchlässe 7, 8 beider Ventilaufnahmekörper 5, 6 koaxial zueinander ausgerichtet sind. Der Ventilsitz 14 führt das als Kugelrückschlagventil ausgebildete Ventil schließglied 4. Dieser ergibt sich infolge der unter schiedlichen lichten Weite beider überlagerten Druckmit teldurchlässe 7, 8 an den Kontaktflächen. Es bedarf da her bezüglich der erweiterten, das Kugelventil aufneh menden Bohrung lediglich einer Verstemmung an der dem Ventilsitz 14 abgewandten Bohrungsöffnung oder alterna tiv einer entsprechenden kegelförmig verjüngten Bohrung des Druckmitteldurchlasses 7, um das Ventilschließglied 4 vor dem Herausfallen zu schützen. In einer zur gezeig ten Schnittebene versetzten Ebene, befindet sich das weitere Ventilschließglied, das in der rotationssym metrisch im Ventilaufnahmekörper 6 gelegenen Bohrung (vergleiche Fig. 1) zur Anlage gelangt. FIG. 2 shows a cross section in the plane of the first valve closing element 4 that can be seen from FIG. 1. The first as well as the further valve receiving body 5 , 6 are arranged in overlap such that the pressure medium passages 7 , 8 of both valve receiving bodies 5 , 6 are aligned coaxially to one another. The valve seat 14 guides the valve closing member 4 designed as a ball check valve. This results from the different internal widths of the two superimposed pressure medium openings 7 , 8 at the contact surfaces. It is therefore necessary with regard to the expanded, the ball valve receiving bore only caulking at the bore opening facing away from the valve seat 14 or alternatively a corresponding conically tapered bore of the pressure fluid passage 7 in order to protect the valve closing member 4 from falling out. In a plane offset to the shown cutting plane, there is the further valve closing element which comes into contact with the bore in the rotationally symmetrical position in the valve receiving body 6 (cf. FIG. 1).
Die Fig. 3 zeigt eine alternative vorteilhafte Ausfüh rung des Erfindungsgedankens, wonach beide Ventil schließglieder 3, 4 in einem einzigen Ventilaufnahmekör per 6 geführt sind. Das erste, als Kugelrückschlagventil ausgebildete Ventilschließglied 4 ist innerhalb einer zur Symmetrieachse des Ventilaufnahmekörpers 6 koplana ren Stufenbohrung 10 angeordnet. Der Übergang der Stu fenbohrung 10 ist als Ventilsitz 14 kegelstumpfförmig gestaltet. Der erweiterte Kanalanschluß am Kegelstumpf bildet den das Kugelrückschlagventil aufnehmenden Druck mitteldurchlaß zur Druckmittelquelle 13, beispielsweise zum Bremsdruckgeber, während der verjüngte Kanalanschluß den Druckmitteldurchlaß zum Druckmittelverbraucher 12, beispielsweise zur Radbremse, herstellt. Die der Druck mittelquelle 13 in der Ventilaufnahmebohrung 2 zuge wandte Bohrungsstufe 9, ist in ihrem hydraulischen Durchlaßquerschnitt derart bemessen, daß Druckmittel un gehindert von der Druckmittelquelle 13 in den das Kugel rückschlagventil aufnehmenden Druckmitteldurchlaß gelan gen kann. Ein Herausfallen des Kugelrückschlagventils ist infolge einer ausreichenden Überdeckung der Kugel durch die Bohrungsstufe 9 verhindert. Die Bohrungsstufe 9 übernimmt die Funktion eines Ventilanschlags. Eine weitere dem Druckmittelverbraucher 12 zugewandte Boh rungsstufe 9′ im Ventilgehäuse 1 bildet einen vergrößer ten Öffnungsquerschnitt, um das Einfügen des Ventilauf nahmekörpers 6 in die Ventilaufnahmebohrung 2 zu ermög lichen. Diese Bohrungsstufe 9′ ist beispielhaft als Ver stemmstelle an der Berandung des Ventilaufnahmekörpers 6 ausgelegt. Der Ventilaufnahmekörper 6 nimmt in einer zentral gelegenen Durchlaßbohrung 11 das weitere, vor zugsweise elektromagnetisch betätigbare Ventilschließ glied 3 auf. Zur Zentrierung und Abdichtung der Durch gangsbohrung 11 ist diese in Richtung des Ventilschließ gliedes 3 kegelförmig erweitert, so daß in der Schließ stellung des Ventilschließgliedes 3 die Druckmittelver bindung zwischen der Druckmittelquelle 13 und dem Druck mittelverbraucher 12 nur über das Kugelrückschlagventil in Richtung der Druckmittelquelle 13 und damit zur Druckentlastung des Druckmittelverbrauchers 12 erfolgen kann. Fig. 3 shows an alternative advantageous embodiment of the inventive concept, according to which both valve closing members 3 , 4 are guided in a single valve receiving body by 6 . The first, designed as a ball check valve closing member 4 is arranged within a 6 to the axis of symmetry of the valve receiving body 6 koplana ren stepped bore 10 . The transition from the stepped bore 10 is designed as a frustoconical valve seat 14 . The expanded duct connection on the truncated cone forms the pressure medium passage receiving the ball check valve to the pressure medium source 13 , for example to the brake pressure transmitter, while the tapered duct connection produces the pressure medium passage to the pressure medium consumer 12 , for example to the wheel brake. The pressure medium source 13 in the valve receiving bore 2 facing bore step 9 , is dimensioned in its hydraulic passage cross-section such that pressure medium unhindered by the pressure medium source 13 in the pressure check valve receiving the ball check gelan conditions gelan. Falling out of the ball check valve is prevented due to sufficient overlap of the ball through the bore step 9 . Hole level 9 takes on the function of a valve stop. Another pressure medium consumer 12 facing approximately level 9 'in the valve housing 1 forms an enlarged th opening cross-section to enable the insertion of the valve body 6 in the valve receiving bore 2 to make it possible. This bore step 9 'is exemplarily designed as a caulking point on the edge of the valve receptacle body 6 . The valve receiving body 6 takes in a centrally located through hole 11, the further, preferably before electromagnetically actuated valve closing member 3 . To center and seal the through hole 11 , this is expanded conically in the direction of the valve closing member 3 , so that in the closed position of the valve closing member 3, the pressure medium connection between the pressure medium source 13 and the pressure medium consumer 12 only via the ball check valve in the direction of the pressure medium source 13 and so that the pressure medium consumer 12 can be relieved of pressure.
Gerade für die bei schlupfgeregelten Kraftfahrzeugbrems anlagen verwendeten Elektromagnetventilanordnungen ist dies von Bedeutung, wonach zur Steuerung des Bremsdruck verlaufs zwischen der Radbremse (Druckmittelverbraucher) und dem Bremsdruckgeber (Druckmittelquelle) elektro magnetisch ansteuerbare Ventilschließglieder angeordnet sind. Das hierzu parallel geschaltete Kugelrückschlag ventil ermöglicht zum Zwecke der raschen Druckentlastung der Radbremse jederzeit eine Vorrangsteuerung gegenüber dem zugehörigen elektromagnetisch betätigbaren Ventil schließglied, sobald der Fahrer die Betätigung des Bremsdruckgebers unterbricht.Especially for those with slip-controlled motor vehicle brakes plants used electromagnetic valve arrangements this is important after which to control the brake pressure course between the wheel brake (pressure medium consumer) and the brake pressure sensor (pressure medium source) electro arranged magnetically controllable valve closing elements are. The ball check connected in parallel valve allows for rapid pressure relief priority control over the wheel brake at all times the associated electromagnetically actuated valve closing element as soon as the driver actuates the Brake pressure sensor interrupts.
Der Erfindungsgegenstand zeichnet sich durch eine äußerst kompakte und leicht zu montierende Ventilanord nung aus, ohne hierbei kostenintensive Maßnahmen hervor zurufen. Gerade unter dem Gesichtspunkt einer möglichst kompakten Bauweise läßt die Erfindung es zu, das als Kugelrückschlagventil ausgebildete Ventilschließglied unmittelbar im Ventilsitzkörper des elektromagnetisch ansteuerbaren Ventilschließgliedes zu integrieren. Bei einer Vielzahl von baulich nebeneinander in einem block förmigen Ventilgehäuse angeordneten Elektromagnetventi len wird hierzu kein zusätzlicher Bauraumbedarf benö tigt.The subject of the invention is characterized by a extremely compact and easy to assemble valve assembly without costly measures shout. Especially from the point of view of one if possible compact design, the invention allows it as Ball check valve trained valve closing member directly in the valve seat body of the electromagnetic to integrate controllable valve closing member. At a multitude of structurally side by side in one block shaped valve housing arranged solenoid valves No additional installation space is required for this does.
