Abstract
A flow control valve for use in dispensing fuel or other fluid and which can be facilely installed in the inlet end of an automatic fuel dispensing nozzle. This flow control valve does not incorporate a valve seat, for its piston like valve, and pressure compensation is controlled by the valve and includes a sleeve incorporating a slidable piston therein, a fluid outlet port is provided at one end of the sleeve, and which is capable of being partially closed by the slide of the piston therein, under fluid pressure conditions, to thereby create a pressure drop that eventually forces the piston into the sleeve and to close off the sleeve port openings in order to reduce fluid flow, during a dispensing function.
