ABSTRACT:
A vehicle load force proportioning device compressibly interposable between a sprung portion and an unsprung portion of a vehicle and subjectable to a compressive force of a degree corresponding to the vehicle load, the proportioning device including a pair of axially aligned force-translating piston members having respective pressure areas of different dimensions and having an elastomeric member disposed therebetween for transferring the vehicle load force from one of the piston members to the other and converting the vehicle load force to an operating force for causing a control valve device to emit a control impulse at a degree according to that of the operating force which, relative to the vehicle load force, is either proportionally reduced or amplified depending upon the respective dispositions of the different dimension piston members in the proportioning device relative to the sprung and unsprung portions of the vehicle.
