Abstract
A fluid device for vehicle fuel consumption enhancement including a body defining a compressible chamber therein the body is connected to the throttle linkage to be compressed responsive to movement of the vehicle throttle in the acceleration direction, the chamber housing a fluid therein which is adapted to be expelled through a fluid bleed orifice upon compression of the chamber to control the force of movement of the vehicle throttle, the bleed being preferably variable to control the speed of movement of the vehicle throttle, the device further including a fluid return providing a means for the return of the expelled fluid back into the chamber upon the deceleration of the vehicle throttle and further including a safety valve positioned in fluid flow communication with the chamber and adapted to allow instantaneous expelling of substantially all of the fluid from the chamber responsive to a predetermined large amount of force being exerted against the vehicle throttle and thereby against the compressible chamber in order to provide an override capability in cases of emergency, the device being particularly usable in two configurations wherein one utilizes air as the fluid and h…
