ABSTRACT:
A compressed gas engine (20) has a piston (25) mounted for reciprocating movement within a cylinder (22). A valve (29) is slideably mounted on the cylinder head (31) to control the flow of compressed gas from a source (24) through an inlet (23) to a plenum chamber (28). The valve is arranged to be selectively engaged and opened by the piston to permit flow of compressed gas into the plenum chamber. When the valve is closed, compressed gas within the plenum chamber is permitted to flow into the variable-volume chamber (26). Spent gases are exhausted through ports (69) as the piston approaches its bottom dead center position. Residual gases in the variable-volume chamber are recompressed into the plenum chamber (28) as the piston moves upwardly toward its top dead center position.
