Abstract

The engine has two fixed tubes (4) with holes (5) communicating with ports in the engine cylinders. Other tubes (6), also with holes (7) rotate inside the fixed tubes and communicate with the inlet and the exhaust, being driven in synchronism so as to perform the set intake and exhaust strokes. The inner tubes can be closed at their ends opposite to that connected to inlet or exhaust, and mounted on ball bearings, also having spiral external grooves for the supply of lubricant, and there can be vanes on the ends to assist the flow of inlet and exhaust gases.
