A rotary fluid driven engine includes a stationary housing having a cylinder block rotatably mounted therein and having a plurality of spaced bores. Each bore has a piston reciprocally mounted therein and connected by connecting rods to an eccentric rotor which is rotatably mounted within the housing for rotation about an axis spaced from and parallel with the axis of rotation of the cylinder block. Fluid under pressure is applied is sequence into bores of the cylinder block in accordance with controlled ports to effect movement of the respective piston in the bores and rotation of the eccentric rotor. A plurality of spaced shafts are fixed relative to the cylinder block and engage respective cam surfaces in the eccentric rotor to rotate the cylinder block and a driven shaft connected to said block and to maintain relative rotation of the cylinder block and eccentric rotor and reciprocation of the pistons.
