Abstract: Components are provided for use in systems for dispensing fluids. A resilient diaphragm is provided for a diaphragm pump. The diaphragm includes a pressurizing portion connected with a connecting member to a peripheral mounting flange for mounting the diaphragm in the housing of the pump. The pump housing has a retention wall which can be swaged against the diaphragm flange. The pump housing has a discharge structure with an outlet valve and a restraint structure adjacent the valve to prevent in-venting through the outlet valve. The outlet valve includes a flange which is retained by a retention wall and which projects from the discharge structure and which is swaged into engagement with the outlet valve flange.

Abstract: A valve is provided with a peripheral attachment portion by which the valve may be attached to a dispensing structure through which can be discharged a product from a supply of the product. The valve includes a flexible, peripheral sleeve extending from the peripheral attachment portion. The sleeve has a central elongate portion and two shorter end portions at opposite ends of the elongate portion so that the central elongate portion and the two shorter end portions together define an interior volume. The valve also has a flexible, elongate head extending from the peripheral sleeve. The head includes at least one elongate slit defining two, opposed, elongate, openable regions in the head which are normally closed and which open to permit the discharge of the product therethrough in response to a pressure differential across the head.
