An orifice is provided between the inlet and the chamber for metering the flow of hydraulic fluid therebetween. In addition, regulating means is provided adjacent the orifice and is movable in a timed relation in response to a series of pulse signals for changing the effective flow area of said orifice whereby the pressure in the chamber varies with the integral of the voltage pulses.
