Patent ID: 7814748

Claim:
An exhaust bypass valve assembly for an internal combustion engine comprising: an exhaust bypass valve having valve structure coupled to a rotatable shaft such that rotation of the shaft moves the valve structure between opened and closed positions, an actuator disposed remote from the bypass valve for selectively causing rotation of the shaft associated with the valve structure in opposing directions, and linkage structure connected between the actuator and the shaft to transfer motion of actuator to the shaft, wherein the linkage structure includes pulley and cable structure that comprises: a first pulley coupled to a shaft of the actuator, a second pulley coupled to the shaft associated with the valve structure, and a single Bowden cable wrapped partially around each of the first and second pulleys such that rotation of the shaft of the actuator in a first direction causes the shaft associated with the valve structure to place the valve structure in a first position, and rotation of the shaft of the actuator in a direction opposite the first direction causes the shaft associated with the valve structure to place the valve structure in a second position.
