Abstract
Air motor having a crankcase about which a plurality of expansible chambers are arranged so that a crankshaft journaled within the crankcase can be connected to a bellows of the expansible chamber by a rod assembly. The crankshaft moves a cam means which in turn moves a valve assembly for controlling flow of compressed air into and out of the expansible chambers. Each expansible chamber is formed by a bellows concentrically aligned and placed within a cylinder to form an annular chamber therebetween. The rod assembly is received through a guide and seal means which maintains the rod axially aligned with respect to the expansible chamber, and seals the interior of the crankcase from the expansible chamber assembly. An intermediate chamber is formed between the crankcase and expansible chamber which greatly increases the efficiency of the motor.
