ABSTRACT:
A vehicle suspension height control unit comprising a hydraulic pump operd by reciprocatory action of the suspension dashpot to pressurize an accumulator. Tendency of the sprung mass to go above or below its normal height range actuates a directional valve for either venting liquid from the dashpot to a sump or passing pressurized liquid from the accumulator to the dashpot. Preferably each roadwheel is equipped with one of these hydraulic units, thereby avoiding the complexity of a central hydraulic system and myriad hydraulic lines.
