ABSTRACT:
A foam dispensing gun of the type having a disposable nozzle for mixing and dispensing separate fluid components of a resin system in which a single, relatively large diameter cylindrical nipple projecting from the gun body supplies both components to the interior of the mixing nozzle. The nozzle is retained on the gun by a sliding breech which also pivotally supports a valve actuating trigger to be in an operative position when the breech is moved to retain a nozzle to the gun and disabled when the breech is moved to release the nozzle for reloading and by a molded-in ring which makes a fluid tight seal between the nozzle and the single gun body port. The breech includes a stop member so that the trigger actuating forces are isolated from the nozzle.
