A dispensing head for use in a fluid dispensing system has a base member made from an inert plastic material with locking guide means at the lower section thereof and boss means at the upper section. The boss means has a shoulder a predetermined distance from the locking guide means and a control valve cavity which extends into the base member from the upper surface of the boss means so as to communicate with an inlet for fluid to be dispensed and an outlet for dispensing said fluid respectively disposed in the base member a spaced distance therefrom. A guard member also made of an inert plastic material has a connecting section and a shield section. The connecting section forms a shaped cavity with locking guide grooves on the inner wall of the connecting section so that the guard member in assembled position will operatively engage locking guide means at the lower end and a shoulder at the upper end of the base member. The connecting section of the guard member has an opening thereon and in assembled position the opening is aligned with the control valve cavity to permit means to be connected in the control valve cavity for locking the base member and guard member in assembled position in a fluid dispensing system. Said means including, a thin walled metal insert ultrasonically welded in the control valve cavity, a retaining ring mounted on said metal insert and sized to extend through the aligned opening when the guard member is in assembled position, and a cover member threadibly connected on the extended portion of the retaining ring. A nozzle is removably fitted in the outlet means in the base member, a means is provided in the outlet means to hold the nozzle in assembled position.

Dispensing head assembly for fluid dispensing system and a nozzle

Dispensing head for fluid dispensing systems having elements made from

A cartridge type control valve for replaceable use in the dispensing head of a fluid dispensing system includes, a fluid transfer assembly having a composite fluid transfer chamber means and an inlet duct assembly made of plastic material, the inlet duct assembly includes a longitudinal leg formed integral with the bottom and sidewall of the fluid transfer chamber means and a transfer leg operatively connected to the longitudinal leg and locked to the sidewall to prevent relative rotation thereof, valve means including a valve stem made of plastic material coacting with a valve port formed in the inlet duct assembly to control flow of fluid through the fluid transfer assembly, and an actuating assembly for operating the valve means with a regulator sub-assembly therein having a valve guide made of plastic material disposed for operative connection to the valve stem. Additionally, the fluid transfer chamber means of the fluid transfer assembly includes, a reinforced cup-like member, an elastomeric diaphragm disposed to lie transversely of the cup-like member to form the fluid transfer chamber therewith, and a cover member, the cup-like member and the cover member having interengaging elements with means thereon to securely clamp the edges of the diaphragm therebetween in assembled position. At least one annular reinforcing element is continuous with the rim of the cup-like member and reinforcing ridges are formed in the bottom or floor of the cup-like member.
