Patent ID: 7063307

Claim:
In an apparatus comprising an automobile having at least three wheels and an underside, the underside comprising a structural frame, the automobile having a front end and a back end, the automobile further having an inflatable tire mounted on each of two of the wheels, the two wheels with inflatable tires thereon spaced apart, an improvement comprising an integral means for selectively pneumatically independently raising the front end or the back end of the automobile, the integral means further comprising a first separate means for selectively pneumatically independently lowering the front end and a second separate means for selectively pneumatically independently lowering the back end of the automobile, wherein the integral means for selectively pneumatically independently raising either the front end or the back end of the automobile further comprises a rigid housing, the housing having a telescoping side wall, a top wall, and a housing bottom wall positioned in a facing relationship relative to the housing top wall, with at least one selectively sealable pneumatic plenum positioned within the housing between the housing bottom wall and the housing top wall, and a compressor, and power supply means directed to the compressor for effecting actuation of the compressor, and a pneumatic conduit directed from the compressor to a valve assembly, the valve assembly directing pressurized air from the compressor through the pneumatic conduit to the pneumatic plenum, and a support tube fixedly and orthogonally mounted to the housing bottom wall, with a plate adjustably received within the support tube; the valve assembly including a valve conduit directed therethrough in pneumatic communication with at least one selectively sealable pneumatic plenum and the pneumatic conduit, the improvement further including a rotary relief shaft rotatably received within the valve assembly and extending into the valve assembly conduit to permit selective depressurization of each selectively sealable pneumatic plenum.
