Abstract

Bei einem Axialkolbenkompressor, insbesondere Taumelscheibenkompressor für die Drucklufterzeugung in Kraftfahrzeugen, sind ein ölgeschmiertes Triebwerk (1) und ein ölfrei laufendes Luft-Verdichterteil vorgesehen. Die unter Führung einer Taumelscheibe (5) in Zylinderbohrungen laufenden Kolben (11) weisen an ihrer Rückseite jeweils den durch Kammern (21) gebildeten Saugraum und an ihrer Vorderseite den Druckraum (23) auf. Saugventile (25) sind an den Kolben angeordnet, während Druckventile (29) im durch Kühlöl oder Wasser gekühlten Zylinderkopf (33) vorgesehen sind. Die Abdichtung zwischen ölgeschmiertem Triebwerk (1) und ölfrei laufendem Verdichterteil erfolgt mittels am Außenumfang der Kolbenstangen (13) der Kolben wirkender Abdichtelemente (19). Bei Verwendung von Kühlöl zur Kühlung des Zylinderkopfs (33) dient dieses gleichzeitig als Schmieröl für das Triebwerk (1).

Figure 00000001
In an axial piston compressor, in particular a swash plate compressor for the generation of compressed air in motor vehicles, an oil-lubricated engine (1) and an oil-free air compressor part are provided. The pistons (11) running in cylinder bores under the guidance of a swash plate (5) each have on their rear side the suction chamber formed by chambers (21) and on their front side the pressure chamber (23). Suction valves (25) are arranged on the pistons, while pressure valves (29) are provided in the cylinder head (33) cooled by cooling oil or water. The seal between the oil-lubricated engine (1) and the oil-free compressor part is carried out by means of sealing elements (19) acting on the outer circumference of the piston rods (13) of the pistons. If cooling oil is used to cool the cylinder head (33), this also serves as lubricating oil for the engine (1).
