An actuator assembly for actuating a valve includes an extensible bellow having an open end and a closed end, a stem operable to contact the closed end and to actuate a stopper mechanism, and a driver configured to move the bellow. The movement of the bellow effects movement of the stem to actuate the valve. In one embodiment, the driver acts to compress the bellow, the compression causing movement of the stem to open the valve. The bellow may be hermetically sealed to the valve housing, thereby allowing a higher range of fluid pressures.

Valve actuator assembly

In actuators where an electric motor, via a transmission, drives an activation element intended to cause movement of an adjustable element in the structure in which the actuator is incorporated, particularly within the furniture sector, hospital beds and sickbeds. The level of noise may be reduced in that at least the electric motor () is mounted in tightly fitting recess () in a block () of foam plastics or similar vibration/noise damping material. An additional reduction of vibrations/noise is achieved by inserting a claw coupling () with a gasket of rubber or rubber-like material between the individual claws in the claw coupling.
