The outer periphery of the first piston is in slidable and sealable contact with the inner periphery of the cylinder body and the outer periphery of the inner cylinder is in contact with the inner periphery of the first piston for slidable and sealable movement with the latter and defines a first hydraulic chamber. The outer periphery of the second piston is in slidable and sealable contact with the inner periphery of the inner cylinder and together with the inner cylinder, defines a second hydraulic chamber.
