ABSTRACT:
A four cycle internal combustion engine comprising 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 one or more peripheral lobes corresponding in number to the number of compartment lobes, and with each inner body lobe disposed within a corresponding compartment lobe for movement therein during at least a portion of the orbital movement of the inner body. The inner body is provided with one or more recesses corresponding in number to the inner body lobes and a movable wall member is mounted for movement in each inner body recess to define with the housing and inner body a fluid intake and compression chamber of the engine. The housing and inner body define a variable volume power chamber and a variable volume exhaust chamber in each peripheral lobe of the housing, and passageway means are provided for intercommunicating the intake and compression chamber with intake means of the engine, and with respective power chambers of the engine to transfer compressed fluid to the power chambers during orbital movement of the inner body. Exhaust chambers of the engine respectively communicate with exhaust port means during portions of the orbital movement of the inner body. Several embodiments of the engine are disclosed in the application, and the construction of the engine provides more efficient transfer of fuel combustion power to an output shaft of the engine.
