ABSTRACT:
A rotary valve for an internal combustion engine comprising: a tapered valve body with a passage for flow of gas starting at one end of the taper and terminating in two places 180 degrees apart on the face of the taper; a pair of rigid seals, 180 degrees apart, which are carried by the valve body and alternately seal the opening to the combustion chamber; pressure cavities behind the pads, sealed by a flexible seal, which use the pressure of the compression stroke to bias the pad which is over the opening to the combustion chamber into contact with the area around this opening, forming a gas tight seal; and a drive shaft for rotating the valve body. A clutch is actuated intermittently by an external microcontroller to engage the drive shaft of the valve with a spinning pulley. During the moving portion of the valve cycle the intake or exhaust gases pass through the flow passage. During the stationary period of the valve cycle the compression and combustion strokes of the engine occur.
