ABSTRACT:
A breather valve has a valve body having a fluid passageway terminating in a valve seat, and a pressure pallet having a size commensurate with the valve seat. The pressure pallet has a sealing side oriented to face the valve seat, and is mounted for limited motion towards and away from the valve seat. A flexible diaphragm is secured to the sealing side of the pressure pallet circumferentially outside the valve seat, preferably around an outer periphery of the valve seat. The flexible diaphragm is separated from the sealing side between the first and second circumferences to create an annular cushion over the valve seat. The flexible diaphragm is fluid impervious outside of the valve seat and fluid pervious inside the valve seat.
