Title: Regenerator protector

Abstract: This invention is protector 24 attached to movable regenerator 10 used in a two stroke regenerative, reciprocating, internal combustion engine employing a plunger piston 11 housing movable regenerator 10. The protector 24 has protector valve 26 to allow fluid to flow through protector 24 whenever movable regenerator 10 is away from cylinder head 4. Attached between plunger piston 11 and protector valve 26 is protector valve spring 27 to urge protector valve open whenever movable regenerator 10 is away from cylinder head 4. The advantages of protector 24 are: The regenerator 10 is protected from the combustion heat, and the regenerator fluid volume does not effect the thermal pressure rise process of the engine.
