Abstract

In hydraulic motors and pumps, the shaft of the motor is set in rotation by pressure fluid being injected into chambers which are formed in a circular part. In the region of the chambers, the pressure fluid exerts pressure on the shaft with the interposition of control elements on which a pressure force acts outwards. A drawback of these conventional motors and pumps is the friction between the control element and the circular part, and the seal between the control element and the cavity. According to the teaching of the invention, the control elements are essentially cylindrical elements and, in addition, the walls of the cavities near the surface of the shaft are designed in such a way that an obtuse angle is formed with the surface of the shaft.
