Abstract (en)
[origin: EP0391097A1] In the case of a device for controlling the operation of hydraulic engines with steplessly variable eccentricity, a flow regulating valve being provided between a pump and the hydraulic engine supplied with pressure medium by the pump, and a control valve being provided for adjusting the eccentricity of the hydraulic engine as a function of the operating pressure required by the hydraulic engine, when optimising the pressure in order to keep the speed of rotation of the hydraulic engine constant, the hydraulic engine is provided with a control device (7, 10) which is mechanically connected to the eccentric (3) and transmits an adjustment of the eccentric outwards, this mechanical control device (7, 10) acting on the flow-regulating valve (17) in such a way that the flow-regulating valve (17) controls the quantity of pressure medium fed to the hydraulic engine as a function of the change in the eccentricity, such that the speed of rotation of the hydraulic engine is kept constant. <IMAGE>
