Abstract
A hydrostatic axial piston machine has a housing. In the housing of the hydrostatic axial piston machine, an actuating pressure cylinder is formed at an angle to the drive shaft. A control valve is inserted into the actuating pressure cylinder in a cartridge type of design. In order to enable maximum movement of an actuating piston in the direction toward the control valve, the cartridge is of shortened design. To this end, an actuating pressure port, which is arranged between a high-pressure port and a low-pressure port, and an actuating pressure passage are arranged completely inside the cartridge.
Claims13
A hydrostatic axial piston machine comprising:
- a swashplate;
- an actuating piston coupled to the swashplate, the actuating piston configured to be displaced in an actuating cylinder and configured to adjust an inclination of the swashplate, wherein:
- an actuating pressure chamber, which is arranged in the actuating cylinder, is delimited by a cartridge of a control valve which is inserted into the actuating cylinder,
- an actuating pressure port of the control valve is arranged between a high-pressure port and a low-pressure port of the control valve,
- an actuating pressure passage extends from the actuating pressure port to the actuating pressure chamber, and
- the actuating pressure passage is arranged inside the cartridge.
