A hydraulic planetary piston motor (1) is disclosed having a set of gearwheels (4) comprising an internally toothed annular gear (2) and an externally toothed gearwheel (3) which mesh with one another and form working chambers (5), which chambers are connectable by way of a commutation valve to a suction port and a delivery port (15) respectively, the commutation valve comprising a rotary slide valve (21) and a valve plate (19), the motor also having a driven shaft (7) which is in rotary connection with the rotating part of the set of gearwheels (4). It is desirable for such a motor to be of simple and robust construction. For that purpose, the driven shaft (7) passes through the rotary slide valve (21). |
