Title: Operating device for vehicle component assembly

Abstract: An operating device is provided for operating a vehicle component assembly. More specifically, the operating device moves a movable member between at least two positions. The operating device especially relates to bicycle components that are actuated by a cable or other mechanical linkage. Basically, the vehicle component assembly has a base member, a movable member, a piston member and an actuating device. The movable member is movably coupled to the base member between at least a first position and a second position. The piston member is operatively coupled to the movable member and fluidly coupled to a supply of pressurized fluid to move the movable member from the first position to the second position. The actuating device has an operating component operatively coupled to a valve mechanism and a mechanical coupling assembly. The valve mechanism is arranged to release pressure in the piston member. The mechanical coupling assembly is operatively coupled between the movable member and the operating component to move the movable member from the second position to the first position upon release of pressure in the piston member by the control valve. The mechanical coupling assembly is further arranged to hold the movable member in the first position against the pressure in the piston member.
