ABSTRACT:
A variable valve comprising a first cylinder having an aperture and a second cylinder having a second aperture. The first cylinder moves between a first position and a second position. Preferably, the second cylinder moves in cooperation with the first cylinder such that the first aperture and the second aperture form a variable sized opening when the first cylinder moves from the first position toward the second position. The first aperture and the second aperture preferably rotate. The variable sized opening is preferably in a closed position when in the first position. The valve comprises a block body including a passage for allowing air to pass therethrough. The first cylinder and the second cylinder are coupled to the block body and configured in a predetermined position such that the variable sized opening is in communication with the passage. The valve also includes an axle for driving the first cylinder and the second cylinder.
