PROBLEM TO BE SOLVED: To provide a light-weight and compact internal combustion piston engine of high piston speed and high output applying a spherical body as a basic structure. SOLUTION: A phase casing 80 of a spherical inner shell having an inner face formed by a spherical face G is rotatably fitted in a housing 10 having main bearings 13 fitted on opposite walls. A rotary piston 30 and a swash plate 40 connected by a hinge revolute joint 50 are assembled in the phase casing 80, a pin revolute joint 44 is assembled in the rotary piston 30 to insert the pivoted rotary main spindle 20, and a swash plate ring 43 is rotatably fitted to an orbital clearance 87 of the phase casing 80. Then the rotary main spindle 20 is fitted and inserted to a casing bearing 83 and both main bearings 13 at opposite both sides, and a clearance of an air chamber Fu between plate faces of the rotary piston 30 and the swash plate 40 is changed in accompany with the rotation when the phase casing 80 is reversed by a reversing device mounted at a side of the housing 10. An intake hole In and an exhaust hole Ex of a proper working medium, and an igniter Ig are faced to each air chamber Fu.
