ABSTRACT:
A reciprocating piston motor has the piston biased in return stroke direction and driven in power stroke by air pressure introduced between the head of the piston and a closure across the end of the working chamber cylinder. A valve which closes an exhaust port leading from the working chamber, is opened at the end of the power stroke by working chamber air pressure and the air pressure is evacuated from the working chamber. The valve is returned to closing relation to the port by the returning piston, thereby resetting the motor for another cycle of operation.
