Support for the drive shaft of an axial-piston machine of an inclined axis construction

In a bearing support for the drive shaft of an axial piston machine of an inclined axis construction for pressurized fluids, including at least one piston-sided and one drive-sided axially loadable bearing having stationary outer rings arranged in a bearing housing and of equal load receiving direction towards the piston side, at least the outer ring of one of the bearings being axially supported on the bearing housing and at least one of the inner rings of said bearing being supported on the piston side against the drive shaft;

• at least one pressure cylinder unit having a balancing piston and subjected to pressurized fluid from the pressure side of the machine for balancing the effective axial components of the piston forces between the bearings;
• the improvement comprising:
• said pressure cylinder unit being arranged intermediate the inner rings of said bearings, said balancing piston being located against one of said inner rings and a cylinder portion of said pressure cylinder unit being located against the other inner ring;
• and a passageway in said drive shaft for supplying the pressure chamber of said pressure cylinder unit with pressurized fluid.
