Title:
HYDRAULIC DUAL AXIAL PISTON MACHINE
Document Type and Number:
WIPO Patent Application WO/2012/010137
Kind Code:
A3
Abstract:
The invention relates to a hydraulic dual axial piston machine, comprising a first driving unit and a second driving unit, which are arranged one behind the other in the direction of the axis of a drive shaft and which are oriented opposite each other. The first driving unit is equipped with a first swash plate, which can be pivoted about a first pivot axis in order to change the inclination relative to the axis of the drive shaft, and with a single first actuating piston, which extends at least approximately parallel to the axis of the drive shaft and which at a first end acts on the first swash plate in order to pivot the latter in the one direction and at a second end delimits an actuating chamber. Control fluid flows into said actuating chamber in order to pivot the first swash plate in the one direction and can be forced out of said actuating chamber when the first swash plate pivots in the other direction. The second driving unit is equipped with a second swash plate, which can be pivoted about a second pivot axis parallel to the first pivot axis in order to change the inclination relative to the axis of the drive shaft, and with a single second actuating piston, which extends at least approximately parallel to the axis of the drive shaft.
