ABSTRACT:
An air driven vehicle utilizes pressurized air contained in storage tanks for actuating double-acting cylinders which in turn transmit a driving force to an axle of the vehicle. The compressed air in a first air tank under high pressure is fed to a first actuating cylinder so as to drive a crank which operates a main drive gear in communication with an axle gear attached to the vehicle axle. Upon a reversal of movement of the piston contained in the first actuating cylinder, a supply of exhaust air is directed from the cylinder to a second air pressure tank in which the exhaust air is collected under a lower pressure than the air contained in the first air pressure tank. The exhaust air is prevented from flowing back into the first actuating cylinder through the use of a one-way check valve, and the pressurized exhaust air in the second pressure tank may then be used to impart a driving force to a second actuating cylinder attached to the same crank so as to provide a supplementary force to the main drive gear in propelling the vehicle. The air exhausted from the second actuating cylinder during the return stroke of a piston in the cylinder may then be similarly employed to drive even additional actuating cylinders or may be exhausted to the atmosphere.
