ABSTRACT:
A check valve assembly is adapted to be installed in a pre-combustion chamber for an internal combustion engine. The check valve includes a ball closure element which is responsive to normal fuel/air supply pressure to be held in an open position and is responsive to expansion pressure in the chamber to close the supply line and to prevent back flash of ignited fuel into the supply line.
