A rotary engine with rotary tubular valves for gas inlet and for gas outlet is described. The engine is of the type wherein at least one rotor is eccentrically rotated on a shaft in a housing with variable volume compartments between the rotor and housing. The rotary tubular valves are spaced around and through the housing with the tube axes parallel to the longitudinal axis of the shaft which mounts the rotor and are parallel to each other. The valve tubes are slotted as is the housing leading into the compartments such that in the proper sequence a power providing gas is introduced through the inlet valves into a compartment to provide a movement of the rotor, and then is exhausted through the outlet valves by the rotor. Preferably there are at least two spaced apart cylindrically shaped rotors eccentrically mounted on a single shaft in separate closed housings and the compartments provided by sliding abutments around each rotor and housing. The engine is particularly adapted for use as an external combustion engine, although it can be operated as an internal combustion engine. The engine can also be operated in reverse as a fluid pump by powering the shaft.
