An inner side of the cylinder defines a sleeve chamber and an outer side of the cylinder and the housing defines an actuating chamber therebetween. The first valve assembly is connected to the cylinder and is configured to (i) to allow fluid flow from the sleeve chamber to the actuating chamber and (ii) to prevent fluid flow from the actuating chamber to the sleeve chamber.
