ABSTRACT:
A rotary piston expansible chamber device without phasing gears has a crankshaft whose axis is offset from the center of the closed curve defining the working chamber cross section and a rotary piston operatively connected to the crankshaft through a crankarm so that crankshaft and piston rotate together in a one-to-one ratio and the rotary piston is displaced as it revolves to maintain arcuately spaced apices thereon in continuous sliding and sealing engagement with the working chamber walls and vary first and second expansible chambers formed on opposite sides of the rotary piston from minimum to maximum and back to minimum during each revolution of the crankshaft. The crankarm constitutes sole force transmitting means between crankshaft and rotary piston, and the rotary piston is displaced as it rotates so that a straight line connecting the arcuately spaced apices remains perpendicular to a reference diameter through the center of the closed curve defining the working chamber cross section in all positions of the rotary piston.
