Abstract

Positive pressure pump or motor of a type built up over a roller bearing. The roller curves (12, 13, 14) are of a special design providing a harmoniously varying rolling velocity for the roller bodies (5, 6). The harmoniously changing tangential distances between the roller bodies (5, 6) are used for pumping or for producing rotation by means of a pressure in a liquid medium.
