An axial piston rotary power device can be configured as a four-cycle and two-cycle internal combustion engine, a compressor, a pump, a fluid-driven motor or an expander. The device includes an external stator housing, an internal axial stator and a rotary cylindrical block attached to an end shaft that can rotate within the annular enclosure formed by the two stators. The cylindrical block contains a plurality of cylindrical cavities arranged as pairs of working cylinders. Each cylindrical cavity encloses a double-acting piston assembly comprising two piston heads connected to a middle portion having a pair of axially spaced apart roller cam followers that make roller contact with a guide cam surface protruding from the inside of the external stator housing. The action of the cam roller followers on the guide cam imparts rotation to the cylindrical block when the piston assemblies reciprocate within their respective bores.
