Abstract

A pneumatic motor having a plurality of cylinders, with each cylinder having an expansion chamber (15), defined in part by a piston plate (2); and a diversion chamber (16) which is divided into two chambers by a slide plate (11), with the diversion chambers connected to a pressure supply line (27) and to a pressure diversion line (28). The piston plate is connected to a piston rod (5) by a lock (3). The expansion chamber holds an amount of compressed air held constant throughout the operation cycle. Expansion of the expansion chamber moves the piston plate and piston rod (5) to rotate a crankshaft (5a). At the end of the expansion stroke, the piston rod is disconnected from the piston plate. The expansion chamber is compressed by pressurizing the diversion chamber below the slide plate (11), forcing the slide plate and push rods (7) upwards, which pushes the piston plate upwards, until the piston plate can be held at a top position by a lock (3'). The diversion chamber below the slide plate is pressurized by pressurized air from diversion chambers of cylinders in which the expansion chamber has been compressed, along with supplemental air from a compressor (30).
