DUAL FUNCTION HANDLEBAR MOUNTED ACTUATOR

摘要

A dual function handlebar mounted actuator has first and second function operating devices arranged for activation by movement of a hand operated lever arrangement. The first and second functions operating devices are linked so that a combined first and second function can be activated and the first and second functions are a clutch and a brake function. The actuator has a lever movable between a first and a second position, and a master cylinder having a piston with the lever moving towards the second position to drive a piston from its initial position thereby increasing pressure in the master cylinder. By releasing the lever the pressure within the master cylinder is arranged to return the piston towards its initial position and the piston being returned fully to the initial position upon movement of the lever to the first position.
