Abstract:
Hydrostatic planetary rotation machine comprising a displacer part (1) acting as a drive part or power take-off part and comprising a disc-like rotary valve (3) serving for supplying working fluid 2 and removing said fluid from the displacer part (1), the displacer part (1) having a first rigid housing (4) having a first inner tooth system (5) with a number d of teeth, which cooperates with a first outer tooth system (7), having a number c of teeth, on a rotatable, eccentrically arranged rotary piston (6), the rotary piston (6) having a second inner tooth system (8) which has a number b of teeth and meshes with a second outer tooth system (9), having a number a of teeth, on a centrically mounted shaft (2), where dâˆ’c=1 and bâˆ’a=2, shaft bearings (10, 11) being arranged directly adjacent on the left and right of the displacer part (1) and the disc-like rotary valve (3) and a toothed gear for driving said valve being provided, characterized in that the toothed gear is an eccentric internal gear (12, 13) in which the disc-like rotary valve (3) executes an eccentric movement in orbit about the machine axis.
