Abstract
The valve assembly has inlet and outlet members with valve elements disposed between the two members. The valve is a resilient membrane having one or more through holes. When there is no pressure differential across the valve, the hole walls in the membrane collapse inwards closing off the valve against liquid flow. At or above a threshold pressure differential across the valve, the membrane is stretched which opens up the hole or holes to allow the passage of liquid.
