HYDRAULIC DEVICE INCLUDING A FACE PLATE

摘要

The invention is related to a hydraulic device comprising a housing including pipe ports, a rotor (14) having rotor chambers (9) which are formed by a cylinder (11) and a piston (12) which rotate about a first axis of rotation (m1) and a second axis of rotation (m2). Both axes of rotation extend within a common plane and intersect each other. A face plate (4) including a face plate centre line which coincides with the second axis of rotation (ml) has two or more face plate ports (3) which are each communicating with a pipe port for communicating the pipe port with the rotor chambers (9). An adjustment device adjusts the mutual positions of the face plate (4) and the common plane. Corresponding to the invention a face plate bearing (30, 32) between the face plate (4) and the housing has at least two axes of rotation which intersect the face plate centre line preferably perpendicularly and upon rotating the face plate (4) the common plane rotates with respect to the housing.
