Abstract: The suspension and level control system for vehicles includes, so as to independently control inflation and deflation of left and right front and rear air-springs, corresponding left and right front and rear pneumatic circuits in fluid communication with a pressurized air source. Each air-spring may have at least one air ride cushion reservoir mounted in a parallel pneumatic circuit in parallel fluid communication with the air-spring. Each pneumatic circuit includes a selectively actuable valve for selectively passing pressurized air from the air source into the corresponding parallel pneumatic circuit to selectively inflate the corresponding air-spring thereby raising a corresponding corner of the vehicle; and for selectively venting pressurized air from the corresponding parallel pneumatic circuit to selectively deflate the corresponding air-spring, thereby lowering a corresponding corner of the vehicle.

Abstract: The apparatus of the present invention for selectively actuable relative movement in a first direction between a first vehicle compartment mountable or mounted to a second vehicle compartment includes a first actuator mounted to the first vehicle compartment for actuation in a second direction of a follower mounted on a distal end of the actuator. An elongate channel is mounted to the second vehicle compartment in a first plane substantially parallel to a plane containing both the first direction and the second direction. The second direction is angularly offset in the first plane from the first direction. The channel is generally diagonally offset in the first plane from the second direction. The follower is mountable or mounted in the channel for sliding engagement therealong upon actuation of the first actuator. Actuation of the first actuator causes the relative translation between the first and second vehicle compartments.
