ABSTRACT:
The present invention is directed to a semi-rotating valve assembly that may be used in conjunction with an internal combustion engine. The semi-rotating valve of the present invention comprises a valve shaft disposed substantially within a valve housing, wherein the valve shaft is configured to rotate less than 360 degrees with respect to the valve housing to selectively open and close the valve. The reduced rotation of the valve shaft reduces friction, heat and wear. An interlocking sealing mechanism that may be used in conjunction with the semi-rotating valve of the present invention, along with means for cooling the valve, also are disclosed. Further, means for varying an aperture size associated with the valve also are provided, wherein the means for varying is configured to compensate for differences in engine speed to further improve efficiency and reduce fuel consumption and emissions.
