SELF-CLOSING DISPENSING VALVE.

摘要

A dispensing valve has a valve housing (102) with a fluid conduit (114) with a valve orifice (124) therethrough. A flow control member (160) is within the valve body (103) which is displaceable along an axis from a first position (fig. 6a) in which the flow control member (160) obstructs the flow of fluid through the valve orifice (124), and a second position (fig. 6b) in which the flow control member (160) does not obstruct the flow of fluid through the valve orifice (124). There is a biasing spring in the form of one or more resilient flexible fingers (146) fixed to the valve housing (102) and which are deflected by the displacement of the valve body (103). The fingers are typically in pairs and deflected by a conical camming surface (168) on the flow control member.
