Abstract
An exhaust apparatus for controlling the timing of exhaust operation in two-cycle engines including a pivotally mounted plate positioned in a recess in the upper surface of an exhaust passage. The plate includes a shaft bearing portion above the pivot axis of substantial strength. A plate extending from that bearing portion is reduced in thickness with a upwardly extending ridge at the outer end thereof to define a control surface and sealing mechanism for the plate. The cooperation between the exhaust port and the end of the valve body may be arranged for maximum sealing and maximum wall thickness of the surrounding port.
