Abstract

A valve assembly (12) includes a liquid inlet (16), a liquid outlet (18) and a resilient valve member membrane (20) disposed therebetween, separating the inlet (16) and the outlet (18), having one or more holes (22). When there is no pressure difference across the membrane (20), the walls of the one or more holes (22) are collapsed and no liquid can pass therethrough, and when the pressure difference across the membrane (20) exceeds a certain threshold level, stretching of the membrane (20) causes opening of the one or more holes (22) to allow liquid to pass from the inlet (16) to the outlet (18).
