ABSTRACT:
A compressed air power plant which includes a piston disposed within a cylinder and connected to a drive shaft. The piston is operated through a power stroke and an exhaust stroke upon each rotation of the drive shaft. The power plant includes compressed air means for supplying compressed air at a high pressure and at a second pressure lower than the high pressure. A distributing means is operatively associated with the compressed air means for selectively communicating the high pressure compressed air to the cylinder at the initial portion of the power stroke of the piston. An intake means is operatively associated with the cylinder and the compressed air means for selectively admitting compressed air at the second lower pressure to the cylinder at a predetermined time in the power stroke after the communication of high pressure air to the cylinder.
