Patent ID: 8746205

Claim:
A device for transmission of force from pistons of a piston engine, said device comprising: a balance arm being supported on a shaft at a distance configured to perform a rocking movement around said shaft; a first set of opposed combustion cylinders each having a piston configured to cooperate with alternating power strokes, said piston of each of said combustion cylinders being interconnected by a first combustion piston rod, said first combustion piston rod being supported by a first slide bearing associated with a first hole defined in said balance arm at a distance from said shaft of said balance arm; a second set of opposed combustion cylinders each having a piston configured to cooperate with alternating power strokes, said piston of each of said combustion cylinders being interconnected by a second combustion piston rod, said second combustion piston rod being supported by a second slide bearing associated with a second hole defined in said balance arm at a distance from said shaft of said balance arm opposite said first slide bearing; a first set of opposed energy transforming means connected to said balance arm by a first bearing between said first sliding bearing and said shaft; a second set of opposed energy transforming means connected to said balance arm by a second bearing between said second sliding bearing and said shaft; and a flywheel connected to said balance arm; wherein said first and second holes each being configured to allow movement of said first and second combustion piston rods respectively while ends of said balance arm travel in a substantial arc.
