Abstract
A suspension control system includes a load support member, a base member and a moveable element attached to the base member and the load support member. The load support member is moveable relative to the base member through the moveable element. An accumulator is in fluid communication with the moveable element. A locking circuit is disposed between the moveable element and the accumulator and is selectively activatable to sustain the load support member in a fixed position. The locking circuit includes a pressurized fluid supply and a flow blocking mechanism operably engaged with the pressurized fluid supply. The flow blocking mechanism is urged to block fluid communication between the moveable element and the accumulator when the locking circuit is selectively activated.
