Abstract

A driving or operating machine with at least two cooperating working elements, of which at least one can rotate in a box ring, box front parts arranged on either side of the working elements and held together by means fixing, such as screws, and a compensating element that, on the one hand, rests against the working elements, while on the opposite side is loaded by a compensating pressure, characterized in that the compensating element is made in the form of plate and are arranged with their marginal part between the box ring and a box front part, and because two gasket rings of different peripheral length form a compensation chamber charged by the compensation pressure.
