Abstract of the Disclosure Disclosed is a cartridge-type flow control valve principally for use in public drinking fountains. The cartridge-type valve includes a substantially cylindrical housing open at one end. Mounted within the housing is a fluid transfer member which includes an integrally formed fluid transfer chamber, inlet nozzle and outlet nozzle. A valve stem slidably extends into the fluid transfer chamber and is sealed by means of O-rings. The valve stem includes a substantially cylindrical eccentric protrusion which can be used to regulate the amount of flow through the cartridge valve. The eccentric protrusion is adjacent to the inlet bore to the fluid transfer chamber and thus, by rotating the valve stem, the gap between the eccentric protrusion and the inner wall of the fluid transfer chamber at the inlet bore can be varied. Varying this gap allows some amount of flow control. The valve stem has attached thereto a valve stem cap. There is integrally formed with the valve stem cap a coiled section which acts in conjunction with the steel spring surrounding the valve stem to drive the valve stem into closed position when pressure is released from the valve stem.
