摘要： An exhaust valve assembly has a valve actuator, a first valve part (FVP) operatively connected to the actuator, a second valve part (SVP), and at least one auxiliary valve operatively connected to the second valve part. When the actuator is in a first position, the FVP is in a fourth position, the SVP is in a seventh position and the at least one auxiliary valve is in a ninth position. When the actuator is in a second position, the FVP is in a fifth position, the SVP is in the seventh position and the at least one auxiliary valve is in the ninth position. When the actuator is in a third position, the FVP is in a sixth position, the SVP is in an eighth position and the at least one auxiliary valve is in a tenth position. The second position is intermediate the first and third positions.

摘要： An exhaust valve assembly for a two-stroke internal combustion engine has a valve actuator having a first pressure chamber and a second pressure chamber, and a valve operatively connected to the valve actuator. The first and second pressure chambers are adapted for selectively receiving one of a first pressure and a second pressure. The first pressure is higher than the second pressure. The valve actuator moves the valve between at least a first valve position and a second valve position. The valve actuator moves the valve to the first valve position when the first pressure is supplied to the first pressure chamber and the second pressure is supplied to the second pressure chamber. The valve actuator moves the valve to the second valve position when the second pressure is supplied to the first pressure chamber and the first pressure is supplied to the second pressure chamber.
