ABSTRACT:
A piston apparatus has a first pair of spaced-apart cylinders aligned along a cylinder axis. There is a pair of pistons, each piston being slidably received in one of the cylinders for reciprocation along the axis. A pair of spaced-apart crank members are on opposite sides of the cylinder axis. The crank members have parallel axes of rotation. Gears mechanically couple the crank members together for rotation at the same rotational speed and in the same direction. A crank connecting member has a longitudinal axis and opposite ends. Each end is connected to one of the crank members a distance from the axis of rotation thereof. A piston connecting member rigidly interconnects the pair of pistons and has a bearing for supporting the crank connecting member to permit relative movement between the piston connecting member and the crank connecting member along the longitudinal axis of the crank connecting member and for carrying the piston connecting member and the crank connecting member together in movement parallel to the cylinder axis.
