FLUID DISPENSING COMPONENTS

摘要

Components are provided for use in systems for dispensing fluids. A resilien t diaphragm (34) is provided for a diaphragm pump (30). The diaphragm (34) includes a pressurizing portion (52) and annular base wall (54) connected wi th a connecting member (58) to a peripheral mounting flange (60) for mounting t he diaphragm (34) in the housing (32) of the pump (30). The pump housing (32) h as a retention wall (70) which can be swaged against the diaphragm flange (60). The pump housing (32) has a discharge structure (36) with an outlet valve (3 8) and a restraint structure (130, 132) adjacent the valve (38) to prevent in- venting through the outlet valve (38). The outlet valve (38) includes a flan ge (160) which is retained by a retention wall (120) and which projects from th e discharge structure (36) and which is swaged into engagement with the outlet valve flange (160).
