Patent ID: 7328647

Claim:
Hydraulic device comprising a housing with a rotor which can rotate in the housing about a first axis and has fixedly mounted pistons, a number of cylindrical drum sleeves which each, together with a fixed piston, form a chamber of variable volume, and a drum plate for supporting the drum sleeves on the side remote from the fixed pistons, the drum plate having a second axis, which intersects the first axis at an angle, and clamping means for holding the drum sleeves against the drum plate, characterized in that the clamping means are designed in such a manner that drum sleeves can move in the radial and tangential directions along the drum plate, and the movement in the tangential direction can be at least double the radial movement which occurs in the event of synchronous rotation between the drum plate and a drum sleeve as a result of the angle between the first axis and the second axis.
