Abstract
A compressed air engine comprises a housing and an impeller body fixed on a primary power output shaft and located within the housing. An ejecting inlet ejects air to the impeller body in the housing. Working chambers are provided on the impeller body. The inner surface of the housing closes the working chambers so that the compressed air ejected to the working chambers pushes the impeller body to rotate and is temporarily stored in the working chamber, and an ejecting outlet is provided on the housing so that the compressed air temporarily stored in the working chamber expands outwards when the compressed air is rotated to the gas ejecting outlet and do work to further push the impeller body to rotate.
