Abstract

Hydraulic motor with a first unit attached to a shaft (11) with a number of radially operating piston cylinder units (17, 18, 19). There is a second unit (13) with at least one cam guide (15, 16) against which the piston cylinder units (17, 18, 19) press whilst under pressure in order to produce a relative turning movement between the first and the second unit (12 or 13). A valve system (30) surrounding the shaft (11) is fitted close to the first unit (12) to supply pressure liquid to the inlet of each piston cylinder unit. The valve system is fixed relative to the second unit so that the first unit is turnable relative to the valve system. A pressure device is fitted on the shaft retains the valve system against the first unit in an axial direction. The first unit and the valve system work together with the pressure device so that the forces separating the first unit and the valve system can be transmitted to the shaft and produce a force countering the separating movement on the shaft.
