Abstract

Bei einem Kompressor, welcher für die Druckluftversorgung in Kraftfahrzeugen als auch für stationäre Anlagen verwendbar ist, ist für die Kühlung des Kompressor-Druckbereichs einschließlich Zylinderkopf (17) und für die Schmierung des Triebwerkbereichs einschließlich Antriebswelle (3) und Taumelscheibe (5) eine dauerhafte Ölfüllung vorgesehen. Der durch die Kompressions- und Reibungswärme aufheizbare Druckbereich des Kompressors und der Triebwerksbereich des Kompressors sind durch Rückschlagventile (39, 41) voneinander getrennt, wobei Fördermittel (Pumpenrad 47) vorgesehen sind, welche das Öl zwischen Triebwerksbereich und Druckbereich im Umlauf transportieren, derart, daß das im Druckbereich erwärmte Öl im Triebwerksbereich abgekühlt wird. Durch die Kühlung des Öls im Triebwerksbereich ist es möglich, einen mittleren Gehäuseabschnitt (23) des Kompressorgehäuses als auch den die Kolbenanordnung aufnehmenden, durch den Zylinderkopf (17) begrenzten Gehäuseabschnitt (85) aus Kunststoff zu fertigen.

Figure 00000001
In the case of a compressor that can be used for the compressed air supply in motor vehicles as well as for stationary systems, a permanent oil filling is required for cooling the compressor pressure area including the cylinder head (17) and for lubricating the engine area including the drive shaft (3) and swash plate (5) intended. The pressure area of the compressor, which can be heated up by the heat of compression and friction, and the engine area of the compressor are separated from one another by check valves (39, 41), conveying means (impeller 47) being provided, which transport the oil between the engine area and the pressure area in circulation, such that the oil heated in the pressure area is cooled in the engine area. By cooling the oil in the engine area, it is possible to manufacture a central housing section (23) of the compressor housing as well as the housing section (85) receiving the piston arrangement and limited by the cylinder head (17) from plastic.
