An improved combustion engine, compressor, pump, or fluid driven motor in single cylinder (20 of Fig 1) or multiple cylinders (20 of Fig 13), versions wherein a normally cylindrical rotor (50) external to drive or driven bearings (64, 65, 65A, 65B), has a patterned cam track (between 52 and 53) for transforming the piston (32) linear reciprocating motion to rotary motion. Two cam tracks (52, 53) can be offset coaxially to allow for continuous unidirectional rotation of said bearings.
