Abstract: A multi-unit rotary expansion engine of the Wankel type capable of operating with pressurized gaseous or vaporous fluid. Each unit has a rotor housing within which a multi-lobed rotor rotates with and about an eccentric or crank portion of a crankshaft drivably connected to the rotor, the rotor and housing defining therebetween a plurality of working chambers which successively expand and contract in volumetric size as the rotor rotates relative to the housing. Each unit includes a plurality of spaced inlet ports and exhaust ports communicating with the working chambers to admit pressurized fluid into the latter and pass exhausted pressurized fluid from the working chambers. Valve means is provided for each of said inlet ports for controlling admission of pressurized fluid into the working chambers for a period of more than 90* of rotation of the crankshaft. The rotors of the multi-unit expansion engine are angularly offset relative to each other 180* so that with the timing of operation of the intake valves at least one inlet port is open to its associated working chamber and instant starting of the mechanism upon application of pressurized fluid to the inlet ports is achieved.
