摘要： A crankshaft rotary valve that controls fluid flow between a port located circumferentially on the crankshaft and a crankcase chamber formed by a piston, cylinder, crankcase and crankshaft. As the crankshaft rotates, a channel in the crankshaft communicates with the port and allows fluid flow to pass through the channel into a passageway that communicates between the channel and the crankcase chamber. The diameter of the crankshaft bearing surface is at least the stroke distance to greatly simplify manufacturing and assembly.
