Abstract:
1. A disposable pump for a liquid dispensing system which comprises a compressible container, comprising: a housing forming a chamber and a dispensing opening, wherein the pressure in the chamber is varied for pumping liquid from the container to the chamber, and further from the chamber to the dispensing opening; and a regulator fixedly arranged in the chamber for regulating a flow of liquid between the container and the chamber, and between the chamber and the dispensing opening, the regulator comprising wherein the pump assumes a closed position, in which a volume of liquid is drawn from the container to the chamber by a negative pressure created in the chamber, and a dispensing position, in which a volume of liquid is drawn from the chamber to the dispensing opening, wherein the outer valve is displaceable between a symmetrical position which corresponds to said closed position of the pump, where the outer valve is in sealing contact with the housing, and a tilted position which corresponds to said dispensing position of the pump, where the outer valve is movable to and from sealing contact with the housing dependent on the pressure in the chamber, and the displacement of said outer valve from said symmetrical position to said tilted position requires an external force applied to the pump and transferred to said regulator.
