  • Valve assembly for a two-stroke engine
    Patent number: 7484482
    Abstract: A valve assembly suitable for use with an exhaust port of a two-stroke internal combustion engine is disclosed. The valve assembly has a valve actuator including a diaphragm and a pressure chamber, and a valve operatively connected to the actuator. The pressure chamber is fluidly connectable to at least one pressure source, via a pressure control device. The valve is movable to one of a first, a second, and a third position when a corresponding one of a first, a second, and a third pressure is supplied to the pressure chamber by the at least one pressure source. The valve is biased towards the third position. The third pressure is insufficient to overcome the bias. The third position is intermediate the first position and the second position. A method of operating the valve assembly is also disclosed.
