In the third embodiment, the valve does not include plunger and cavities as valve mechanism. Rather, the valve includes a body having apertures adapted to fluidly communicate with the upper port, the lower port, the supply valve and the atmosphere based on the position of the body. The body moves in response to the button being moved to the forward, rearward, upward or downward operational positions, and the apertures.
