ABSTRACT:
A back pressure regulator of the diaphragm type. A metal diaphragm is held in a cavity formed by opposed faces of top and bottom portions of the unit. The opposed faces are tapered so that the depth of the cavity is greatest in the central portion of the diaphragm, allowing for movement of the diaphragm. A fluid outlet leading into the cavity at the underside of the diaphragm is sealed by contact of the underside of the diaphragm with an O-ring which surrounds the fluid outlet and extends into the cavity. When the pressure of the fluid in the cavity above the diaphragm is greater than the pressure of the fluid beneath the diaphragm the diaphragm is maintained in contact with the O-ring to prevent flow through the outlet.
