Patent ID: 7581572

Claim:
A shut-off valve for use with a liquid dispensing system, comprising: a) a valve body having a distal face, a proximal surface and a periphery, at least a portion of said periphery being dimensioned to fit snuggly within a liquid delivery nozzle, said valve body comprising at least one unimpeded orifice extending from said distal face to said proximal surface thereof and comprising stopping means attached thereto; b) a cap disposed proximate said distal face of said valve body, said cap having at least one unimpeded orifice formed therethrough, said cap being rotatable between a first, closed orientation and a second, open orientation; and c) means for rotating said cap, said means being spaced apart therefrom, and said cap rotating from said first, closed orientation to said second, open orientation and responsive to a flow of liquid in said liquid delivery nozzle; and d) biasing means operatively connected to said cap; whereby when said cap is disposed at said first, closed orientation, liquid flow from said at least one unimpeded orifice in said valve body is blocked through the use of said biasing means and when said cap is disposed at said second, open orientation, said at least one unimpeded orifice in said cap is aligned with said at least one unimpeded orifice in said valve body thereby allowing liquid to be discharged from said liquid delivery nozzle.
