The invention relates to a device for producing a control pressure which corresponds to a rotary speed imparted to a shaft of a pump which is a part of the device. The device includes a measuring orifice formed by a fixed throttle and a control orifice formed by piston arrangement operating as a controlled throttle. The controlled throttle is responsive to oppositely acting pressures from opposite sides of the fixed throttle. The controlled throttle is in series with a fixed discharge throttle and the control pressure is tapped from between the controlled throttle and the discharge throttle.
