Abstract:
A one-way valve, comprises a valve housing; a valve member provided within the valve housing, the valve member being operative to open and close the valve and comprising a diaphragm with a central orifice to allow fluid to pass from one side of the diaphragm to the other; a valve inlet provided on a first side of the diaphragm; and a valve outlet provided on a second side of the diaphragm; wherein the configuration of the diaphragm and the valve housing biases the diaphragm to seal the inlet at rest.

Claim (Index 17):
A method of operating a valve having a valve seat, on a first side of a diaphragm, against which valve seat the diaphragm forms a seal at rest, wherein the diaphragm further comprises a projection formed in relief on the first side of the diaphragm, such that a sealing surface of the projection contacts the valve seat at rest to form the seal, the method comprising:\n arranging the diaphragm in a valve housing, so that the diaphragm and the housing bias the diaphragm to seal an inlet to the valve chamber, when there is no pressure differential across the diaphragm, wherein the diaphragm has a central portion and a perimeter portion, wherein the central portion comprises a central orifice, and the perimeter portion comprises an outer edge of the diaphragm, and wherein the central portion is thicker than the perimeter portion; and creating a pressure differential across the valve chamber, wherein the pressure at the inlet is greater than the pressure in the valve chamber, and wherein the pressure deforms the diaphragm to unseal the inlet.
