Abstract
A hydrostatic axial piston machine includes a double-acting actuating cylinder configured to adjust the piston displacement. The actuating cylinder has two actuating chambers that are connected to two spatially separated cartridge valves. The two cartridge valves are inserted obliquely into a wall section of the axial piston machine. The wall section on the one hand forms a wall of the housing of the axial piston machine and on the other hand forms a wall of the actuating cylinder.
Claims15
A hydrostatic axial piston machine comprising:
- a drive shaft;
- an actuating piston configured to be moved in an actuating piston plane arranged perpendicularly to the drive shaft;
- and
- a swashplate configured to be adjusted across a neutral point by the actuating piston,
- wherein the actuating piston delimits two actuating chambers acting against each other to which pressurized actuating medium is configured to be respectively supplied via a respective control valve and from which pressurized actuating medium is configured to be respectively released via the respective control valve, and
- wherein respective valve bodies of the two control valves are arranged obliquely to the drive shaft and obliquely to the actuating piston plane.
