Abstract
A hydraulic device () comprises a housing (), a shaft () which is mounted in the housing () and rotatable about a first axis of rotation (), wherein the shaft () has a flange () extending perpendicularly to the first axis (), a plurality of pistons () which are fixed to the flange () at equiangular distance about the first axis of rotation (), and a plurality of cylindrical sleeves () cooperating with the pistons () to form respective compression chambers () of variable volume. The sleeves () are rotatable about a second axis of rotation which intersects the first axis of rotation () by an acute angle such that upon rotating the shaft () the volumes of the compression chambers () change. Each piston () has a piston head () including a ball-shaped circumferential outer side. Each of the pistons () has a modular structure comprising a piston head member () which forms the piston head, a piston pin () which is fixed to the flange () and to which the piston head member () is mounted, and a spacer () which is located at the outer side of the piston pin () and sandwiched between the piston head member () and the flange ().
