US Patent 7814748 Exhaust bypass valve remote linkage

An exhaust bypass valve assembly for an internal combustion engine includes 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 is disposed remotely from the bypass valve for selectively causing rotation of the shaft associated with the valve structure in opposing directions. Linkage structure is connected between the actuator and the shaft to transfer motion of actuator to the shaft.
