A disposable pump, a dispensing system comprising a pump and a method for dispensing liquid

摘要

The present invention relates to a disposable pump for a dispensing system for dispensing liquids, in particular for a system which comprises a compressible container (400). The pump (1) comprises a housing (100) forming a chamber (110), wherein the pressure may be varied, and a dispensing opening (120). A regulator (200) is fixedly arranged in the chamber (110) for regulating a flow of liquid between the container (400) and the chamber (110) and between the chamber (110) and the dispensing opening (120). The regulator comprising an outer valve (220) for regulating the flow between the chamber (110) and the dispensing opening (120). The pump is characterised in the outer valve (220) being displaceable between a symmetrical position which corresponds to said closed position and a tilted position which corresponds to said dispensing position. The displacement requiring external force being applied to the pump (1) and transferred to said regulator (200). The application also includes a dispensing system comprising a pump and a method for dispensing liquid.
