    Patent number: 5151019
    Abstract: A pumping device controlling an amount of liquid passing through a length of tubing accommodated in the pumping device. The pumping device includes inlet and outlet valves located adjacent opposed sides of a tube deforming device. The valves are controllable for restricting the flow of liquid through the tubing, and the deforming device is such that the tubing is first deformed in one direction and then in another direction which tends to restore the original cross-sectional shape of the tubing.
