Abstract
Hydraulic height-adjustment vehicle suspension system includes an arrangment for blocking up the suspension and adapted to prevent the collapsing thereof when the vehicle is kept stationary for a prolonged time period. The blocking arrangement includes a buffer member retractable and engageable in the fashion of a chock or the like, between a movable member of the suspension system and a fixed portion of the body or chassis of the vehicle. Preferably, a control for each buffer member includes a hydraulic receiver operating against the force of a return spring urging the buffer member to its retracted position, and a hydraulic chamber is provided which communicates with the receivers and is urged to its hydraulic fluid delivering condition by the actuation of the hand brake control of the vehicle to its brake applying position.
