Abstract
Description
Die Erfindung betrifft ein Regelventil, insbesondere für Klimakompressoren, welches einen Kältemittelstrom vom Hochdruckbereich zum Triebraumdruckbereich regelt und insbesondere elektromagnetisch betätigbar ist. Derartige Regelventile sind bekannt. Sie werden zwischen dem Hochdruckbereich und dem Triebraumdruckbereich eingesetzt, um Kompressoren zu regeln bzw. eine Ölrückführung vom Hochdruckbereich in den Triebraumdruckbereich gewährleisten zu können.The invention relates to a control valve, especially for Air conditioning compressors, which a refrigerant flow from the high pressure area regulates the engine pressure range and in particular electromagnetically actuated is. Such control valves are known. You will be between High pressure area and the engine room pressure area used to compressors to regulate or an oil return from Ensure high pressure area in the engine pressure area to be able to.
Um extreme Betriebsbedingungen abfangen zu können, ist außerdem ein Druckbegrenzungsventil erforderlich. Dieses stellt im geöffneten Zustand ebenfalls eine Verbindung zwischen Hochdruckbereich und Triebraumdruckbereich dar.To intercept extreme operating conditions can, is also a pressure relief valve is required. This poses in the open Condition also a connection between the high pressure area and Engine compartment pressure range.
Derartige Ventilanordnungen haben verschiedene Nachteile.Such valve arrangements have various disadvantages.
Es sind separate Aufnahmebohrungen für das Regelventil und das Druckbegrenzungsventil im Zylinderkopf erforderlich, wodurch sich erhöhte Bearbeitungskosten und erhöhter Platzbedarf ergeben. Weiterhin entstehen bei der Verwendung von zwei Ventilkonstruktionen als zwei separaten Baugruppen wesentlich erhöhte Kosten.There are separate mounting holes for the Control valve and the pressure relief valve in the cylinder head required which increased Processing costs and increased Result in space requirements. Furthermore arise when using two valve constructions as two separate assemblies essential increased Costs.
Es ist Aufgabe der Erfindung, diese Nachteile zu vermeiden. Die Aufgabe wird gelöst durch ein Regelventil, insbesondere für Klimakompressoren, welches einen Kältemittelstrom vom Hochdruckbereich in den Triebraumdruckbereich regelt, insbesondere elektromagnetisch betätigbar, wobei das Regelventil zusätzlich für eine Druckbegrenzungsfunktion einsetzbar ist. Bevorzugt wird ein Regelventil, bei welchem ein Gehäusebereich des Regelventils in einer Montageöffnung verschieblich verlagerbar ist. Eine erfindungsgemäße Ausführungsform des Regelventils zeichnet sich dadurch aus, dass der untere Teil des Gehäusebereiches des Regelventils mit der Montageöffnung einen Ventilsitz bildet. Weiterhin wird ein Regelventil bevorzugt, bei welchem der Gehäusebereich des Regelventils eine Druckwirkfläche für den Hochdruck aufweist. Auch wird ein Regelventil bevorzugt, bei welchem der Gehäusebereich gegen die Kraft einer Feder verschieblich verlagerbar ist.It is the object of the invention To avoid disadvantages. The problem is solved by a control valve, in particular for air conditioning compressors, which a refrigerant flow regulates from the high pressure area to the engine pressure area, in particular electromagnetically operated, with the control valve in addition for one Pressure limiting function can be used. A control valve is preferred, in which a housing area of the control valve is displaceably displaceable in an assembly opening is. An embodiment according to the invention The control valve is characterized in that the lower part of the housing area of the control valve with the assembly opening forms a valve seat. A control valve is also preferred, in which the housing area of the control valve has a pressure effective area for the high pressure. Also a control valve is preferred in which the housing area is displaceably displaceable against the force of a spring.
Ein erfindungsgemäßes Regelventil zeichnet sich dadurch aus, dass der Gehäusebereich einen kragenförmigen Absatz aufweist. Vorzugsweise ist der kragenförmige Absatz in einer Überwurfkappe angeordnet, welche dem kragenförmigen Absatz einen axialen Hub, beispielsweise von 0,2 mm, ermöglicht. Weiterhin wird ein Regelventil bevorzugt, bei welchem der kragenförmige Absatz mit einer Federkraft beaufschlagbar ist.A control valve according to the invention is distinguished characterized in that the housing area a collar-shaped Has paragraph. The collar-shaped shoulder is preferably arranged in a cap, which the collar-shaped Paragraph allows an axial stroke, for example of 0.2 mm. Furthermore, a control valve is preferred in which the collar-shaped shoulder can be acted upon by a spring force.
Ein erfindungsgemäßes Regelventil zeichnet sich dadurch aus, dass am Gehäusebereich zwischen dem Gehäusebereich und der Montageöffnung eine Dichtungseinrichtung, wie z. B. ein O-Ring, angeordnet ist. Bevorzugt wird auch ein Regelventil, bei welchem die Feder durch eine Überwurfkappe am Zylinderkopf oder am Kompressorengehäuse oder am Zylinderblock abgestützt wird. Weiterhin wird ein Regelventil bevorzugt, bei welchem die Federvorspannkraft durch eine Vorrichtung an der Überwurfkappe einstellbar ist. Auch wird ein Regelventil bevorzugt, bei welchem die Wirkfläche für den Triebraumdruck möglichst klein oder im Wesentlichen unwirksam gegenüber der Wirkfläche für den Hochdruck ist.A control valve according to the invention is distinguished characterized in that on the housing area between the housing area and the assembly opening a sealing device, such as. B. an O-ring is arranged. Also preferred is a control valve in which the spring passes through a cap is supported on the cylinder head or on the compressor housing or on the cylinder block. Furthermore, a control valve is preferred in which the spring preload force through a device on the cap is adjustable. A control valve is also preferred, in which the effective area for the Drive room pressure if possible small or essentially ineffective against the effective area for the high pressure is.
Die Erfindung wird nun anhand der Figuren beschrieben.The invention is now based on the Figures described.
