Abstract
A pump includes a main chamber and a pair of valves on opposite ends of the main chamber. The respective valves each contain a freely movable member to selectively open and close each respective valve, wherein the freely movable member is formed from at least some of the same material used to form a chamber portion of the respective valves. A force applicator is coupled relative to the main chamber to alternately induce a suction action and an expulsion action.
