CA 2183576

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.

Distributeur comprenant un boîtier (102) percé d'un conduit (114) où circule le fluide et d'un orifice (124). Un élément de régulation du flux (160) placé dans le corps (103) du distributeur se déplace le long d'un axe, entre une première position (fig 6a) d'arrêt du flux et une seconde position (fig 6b) laissant passer le flux à travers l'orifice (123) du distributeur. Un ressort chargé consistant en un ou plusieurs doigts élastiques flexibles (146) fixé au boîtier (102) du distributeur et défléchis sous l'effet du déplacement du corps de distributeur (103), les doigts, normalement groupés par paires, étant actionnés par une surface en forme de came (168) conique prévue sur l'élément de régulation du flux (160).
