Description

The shape of the conventional valve of a heat engine is a cocoon (umbrella) type valve.
Before the war, British engineer Cross and Aspin both invented the rotary valve

The present invention relates to ignition ignition of rotary cone valves of machines and heat engines. Before the war, British engineers Cross and Aspin both invented the rotary valve. Although their invention was epoch-making, they were seized by friction with the cylinder head and were not practical. It seems promising in Japan in the 1950s, and some companies tried simple cylindrical rotary valves, but cooling and lubrication did not work well, and they burned directly and were unable to operate continuously. In addition, there were problems with ignition and ignition, and all were abandoned.
