Abstract (en)

The hydraulic motor consists of a fixed housing (2A,2B,2C,2d) with a reactor unit (4) and a cylinder block (6) which rotates about an axis (10). It has an internal fluid distributor (16) which is fixed to the housing in relation to the axis, and one section (2C) of the housing forms a distribution cover over it. The distribution cover and distributor have first and second axial sections (70,72) with corresponding cavities (76,78) to receive a locking pin (80). The pin locks the two sections together while permitting a slight movement of the distributor relative to the cover and holds the two together during assembly.
