A general purpose fluid displacement device for use as an external combustion engine, a compound expansion engine, a hydraulic pump, or as an air compressor. At least one bank of circumferentially spaced pistons are operably connected to and radially disposed about a rotor member that is eccentrically disposed to an imaginary circle collectively defined by said pistons such that the amount of eccentricity of said rotor determines the throw of said pistons as the pistons orbit the rotor attendant operation of the device. The ends of the generally cylindrical device are capped by longitudinally spaced circular band members that rotate conjointly with the pistons and which have formed therein a plurality of ports corresponding in number to and in fluid communication with the rotating cylinders within which said pistons are reciprocably moveable, and by stationary circular band members having fluid intake and exhaust ports, said rotating and stationary ports intermittently and transiently aligning attendant operation of the engine. Several types of combustion chambers, several means for effecting in-unison movement between the rotor and the pistons, and several types of noise-attenuating exhaust ports are also disclosed.
