Abstract

A valve assembly for liquid transfer, including a liquid inlet, a liquid outlet and a valve member disposed between the inlet and outlet. The valve member including a resilient membrane separating between the inlet and the outlet, the membrane having one or more holes. In a state where there is no pressure difference between the membrane's two sides, the walls of the one or more holes are collapsed and no liquid can pass therethrough, and in a state where the pressure between the two sides of the membrane exceeds a certain threshold level, the stretching of the membrane causes opening of the one or more holes to allow liquid to pass from one side of the membrane to the other.
