ABSTRACT:
A pressure responsive control body in the housing of a fluid handling device has a control face which abuts against the control face at one axial end of a rotor which is provided with working chambers for the inflow and expulsion of a fluid. A portion of the control body extends into a pressure chamber of the housing and the control body is movable axially of the housing. The control body seals a portion of the pressure chamber by means of an eccentrically located cylindrical shoulder a portion of which extends radially beyond the control face. This insures that the position of the pressure center of the eccentric shoulder relative to the axis of the rotor is the same as the position of the pressure center between the control faces. Such positioning of the pressure centers guarantees a smooth running of the control face on the rotor relative to the control face on the control body and prevents relative tilting or adherence of the control faces to each other so that the control mirror between the control faces operates with a high degree of efficiency even at high fluid pressures and at a high RPM of the rotor.
