Abstract
A cartridge type regulator and shut-off valve assembly for a water cooler includes a hollow cylindrical body received in a mating bore in a casting which is part of the cooler. The cartridge includes a hollow cylindrical body which, at its inner end, is formed with an inlet passage and an outlet passage connected to each other by a valve-controlled opening in the inlet passage. This opening faces axially inwardly of the body while the valve faces outwardly and is carried by an axially movable stem. A manual actuator is depressed to slide the valve stem inwardly and move the valve away from the opening and the valve is returned by a spring to the closing position when the actuator is released. The valve-controlled opening, as well as a part of the inlet passage, is formed in a bar which extends diametrically across the inside of the body and is an integral part of the latter so that the opening does not shift or creep even if the parts are made of molded plastic. Assembly of the valve stem is facilitated by forming it in parts with the inner part being U-shaped. The valve is carried on the crosspiece of the U and the legs of the U straddle the bar and are formed with hooks which snap into engagement with hooks on another part of the stem so that the parts form a unitary stem.
