ABSTRACT:
A pressurized-fluid-operated engine having a plurality of reciprocatable pistons carried within cylinders through connecting rods with an output shaft. The engine is adapted to operate on pressurized air or pressurized gases, without combustion, and it includes a recirculation device of the ejector type to provide recirculation of a part of the lower pressure exhaust gas and to permit mixing of the recirculated exhaust gas with incoming inlet gas. The device is particularly adapted for use where the source of compressed gas provides a very high pressure of gas, but a relatively low volume, and it permits the mixing of very high pressure inlet gas with lower pressure exhaust gas to provide an operating gas a sufficiently high level to provide a desired engine output.
