Hydraulic machine e.g. swash plate axial piston machine, has two flexible elements made of plastic or steel and arranged in pressure chambers for receiving pressure fluctuations in servo-adjusting device

摘要

The machine has a hydraulic servo-adjusting device that comprises servo pistons (2) in servo cylinders (1), between which two pressure chambers (7a, 7b) are formed. The servo pistons transfer an adjusting force on a servo arm (3) during pressure change in the pressure chambers. Two flexible elements (8a, 8b) made of plastic or steel are arranged in the pressure chambers for receiving the pressure fluctuations in the servo-adjusting device. Force transferred on the servo arm by the servo pistons causes a change of angle position of a swash plate (6) and/or an inclined axis.
