ABSTRACT:
A four-cycle internal combustion engine comprises a housing defining an internal compartment having one or more peripheral lobes, an inner body mounted in the housing for non-rotational orbital movement and having a plurality of peripheral lobes corresponding in number to the number of compartment lobes, and with a peripheral recess in the inner body between inner body lobe. A movable wall member is mounted for movement in each inner body peripheral recess and defines with the housing and inner body, a variable-volume fluid intake and compression chamber. The inner body is mounted in the housing compartment so that each of its peripheral lobes moves in a circular orbit into a respective one of the compartment lobes during movement of the inner body, and the inner body lobe, housing, and movable wall member define a variable-volume power chamber and exhaust chamber in each of the compartment lobes during movement of the inner body. The inner body is operatively connected to a power output shaft to impart rotary motion thereto during orbital movement of the inner body, and the peripheral wall of each inner body lobe is configured so as to impart forces of combustion in the power chamber at a substantially right angle to the crank angle of the power output shaft during the major portion of the power cycle of the engine. The housing is provided with intake and exhaust port means communicating with the internal compartment, and passageway means are located in the inner body and housing to intercommunicate the intake and compression chamber with the intake port means and the power chamber during a portion of orbital movement of the inner body, and to communicate the exhaust chamber with the exhaust port means during a portion of the movement of the inner body.
