C. engine comprises a hollow part-spherical piston 41, Fig. 1 having an upstanding vane 40, Fig. 12, having three wave-like formations formed with a peripheral groove 1 to receive a sealing element 23, which is urged outwardly by centrifugal force and counterbalanced by weights 22 to seal against the part-spherical surface (not shown) of the engine casing. The piston is formed with an inwardly directed flange, Fig. 7, which through tapered roller bearings 17 and a ball bearing 18 co-operates with an inclined plate 5a which is formed in two parts 5b and integral with the engine shaft 5. Internally-toothed gears 15 secured to the piston mesh with stationary pinions 21 so that on rotation of the shaft 5 the plate 5a rotates to sequentially vary the volume of working chambers formed between the vane and the engine casing. Further seals 25, Fig. 11, having counter-weights 31 swivel around pins 25a and stationary packing means 24 in the casing seal between the part-spherical surfaces of the piston and casing. Fuel air mixture or alternatively air only is admitted through an inlet 3, Fig. 4, to a working chamber 7 where it as compressed on rotation of the piston. At minimum volume (working chamber 6), the charge is ignited by a spark-plug or alternatively fuel is injected with the resulting gases of combustion expanding to rotate the piston and finally exhausting through an outlet port 4. Each working chamber has associated therewith an inlet port, an outlet port and one or more spark-plugs or fuel injectors. Working chambers are arranged on both sides of the piston and the engine may be arranged to fire sequentially six times during each revolution of the piston or two firings may occur simultaneously three times during each piston revolution. The casing may be water or air-cooled and the piston may be oil-cooled or cooled by air/fuel mixture. Oil for lubricating the piston and bearings and for cooling the piston when it is oil-cooled is admitted to the engine through an axial duct in) the shaft 5, passes radially outwardly by centrifugal force and returns to sump through further ducts 26 in the casing. Thrust bearings 16 between fixed sleeves carrying the pinions 21 and the piston may be magnet-type ball bearings. One side of the piston may be used as the power side of an internal combustion engine and the other side, with suitably altered porting, as a compressor therefor. Two or more pistons may be arranged one behind the other on a common shaft.
