Engine with two rotary pistons and oscillating pistons - have L=shaped piston, shorter foot having guide lug guaranteeing perfect lateral seal of chamber determined by piston movement

摘要

The rocking piston engine has L-shaped rocking pistons pivoting around a pin (20) at the joint of the piston (10) and its foot (25). The foot carries a guide lug (24) which slides in a slot (16) hollowed in the sides (26) of the sepn. partition (21) definining the reciprocation movement of the piston. The foot moves in a gap in the rotary piston and the guide lug crosses the piston through a semi circular hole. Each rotary piston is closed by two circular caps (1) having two holes for the passage of the lug, but also ensures a perfect seal the rotary piston chambers. USE - For four strokee engines.
