Abstract

Eine Axialkolbenmaschine hat eine Triebwelle (3) und einen an der Triebwelle (3) vorgesehenen Triebwellenflansch (4), an welchem sich Kolben (20) abstützen, die in Zylinderausnehmungen (18) einer Zylindertrommel (7) verschiebbar sind. Ein Steuerkörper (5) ist an einer Stützlagerfläche (34) gelagert und weist einen an einer ersten Steueröffnung (39) mündenden ersten Druckkanal (40) und einen an einer zweiten Steueröffnung (46) mündenden zweiten Druckkanal (41) auf. Über die Druckkanäle (40, 41) sind die Zylinderausnehmungen (18) zyklisch alternierend mit einer Niederdruckleitung und einer Hochdruckleitung verbindbar. Erfindungsgemäß ist zumindest einer der Druckkanäle (40, 41) mit zumindest einem an einer der Stützlagerfläche (34) gegenüberliegenden Gegenfläche (35) des Steuerkörpers (5) ausmündenden Entlastungs-Kanal (30, 31) und/oder Schmier-Kanal (32, 33) verbunden.

Figure 00000001
An axial piston machine has a drive shaft (3) and a drive shaft flange (4) provided on the drive shaft (3), on which pistons (20) are supported, which can be displaced in cylinder recesses (18) of a cylinder drum (7). A control body (5) is mounted on a support bearing surface (34) and has a first pressure channel (40) opening at a first control opening (39) and a second pressure channel (41) opening at a second control opening (46). The cylinder recesses (18) can be connected cyclically alternately to a low-pressure line and a high-pressure line via the pressure channels (40, 41). According to the invention, at least one of the pressure channels (40, 41) with at least one relief channel (30, 31) and / or lubrication channel (32, 33) opening out on a counter surface (35) of the control body (5) opposite the support bearing surface (34) ) connected.
