摘要： An internal combustion engine has an orbital inner body or piston member (21,200) working in a housing (10, 204) and eccentrically connected with a power output shaft (36,38) to rotate the latter while orbiting within the housing.
A compact, efficient design is obtained by associating each pair of interfitting lobes (16,28; 18,30; 20,32), formed respectively in the housing and inner body and together providing a combustion chamber (70) and an exhaust chamber (72), with an intake and compression chamber (56) formed by a recess (42, 44, 46) in the inner body and a slidable element (46) accommodated therein. During orbital movement of the inner body, the slidable element (46) slides into sealing engagement with the associated lobes to form a sealed space containing the chambers (70,72). The housing, inner body and slidable element (46) feature an arrangement of grooves (86, 88, 90) which, during the orbital movement, cause fluid to be admitted to the chamber (56) for compression therein, then admit the compressed fluid to the combustion chamber, and thereafter exhaust the expanded fluid from the exhaust chamber (72). Each inner body lobe includes a surface (70a) parallel to the axis of eccentricity whereby combustion forces act normal to the axis in order to attain enhanced efficiency of power transfer to the shaft (36, 38).

摘要： An internal combustion engine having combustion chambers that rotate about a main shaft axis in a step-wise manner. First and second rotors each have elongate pistons that are interdigitated so that when one rotor rotates with respect to the other rotor, some chambers between the pistons are reduced in volume and other chambers are increased in volume. Respective one-way bearings connect the first and second rotors to the main shaft to incrementally rotate it. Fuel mixture and exhaust apparatus is connected to one end of the engine to feed a fuel mixture to the increasing-volume chambers and extract the exhaust from other decreasing-volume chambers. Simultaneously, yet other chambers are experiencing compression and ignition cycles. An oil pump is driven by the first and second rotors for circulating a lubricant from a reservoir, through the engine parts to be lubricated and back to the reservoir to cool the lubricant.
