  • Patent number: 4615512
    Abstract: A vehicle suspension strut in which an internal elastomer sleeve is used as an air/oil separator bladder. Air pressure introduced to the chamber formed by the sleeve will expand the sleeve creating a pressure in the hydraulic fluid which acts on the area differential of the piston to create an adjustable lifting force for vehicle height control. Also as the strut works going into jounce, shock absorber oil displaced by the rod is taken up by the air volume trapped inside of the air sleeve. A main suspension spring is mounted to and around the reservoir tube of the strut which may be steerable.
