Abstract

See full text

A barrel-type internal combustion engine 1 has double-ended pistons 10 reciprocally movable within cylinders 2 disposed in a ring about a central axis 3. The pistons 10 are interconnected with a central drive member 16, by means of a cam 17 carried by the drive member 16, whereby reciprocatory movement of the pistons causes the drive member to rotate. A closed circuit pressurized vapor system which makes use of waste engine heat, includes an expander 110, enabling mechanical energy obtained from expansion to be applied to the rotary member 16, to augment the power generated by the pistons 10. The expander 110 is formed by a hollow interior 31 in the rotary member 16, which houses a shaft 37, the shaft 37 defining with the member 16 an annular chamber 42. The rotary member 16 and shaft 37 rotate eccentrically relative to each other and in the same direction. Sealing components 32, 35 cooperate so as to divide the chamber 42 into relatively high and low pressurized vapor zones as the drive member 16 and shaft 37 rotate eccentrically.
