Summary:A pump in which a tube having a valve assembly near to its lower end is reciprocably mounted on a support. The valve assembly is made up of a valve seat, a valve member and means for returning the member adjacent to the valve seat. In use, the lower end of the tube is immersed in a liquid and the tube is reciprocated relative to the liquid. Liquid flows through the valve assembly when the tube moves in one sense relative to the liquid but the valve member cooperates with the valve seat to prevent return flow when the tube moves in the opposite sense.
