Fuel tank one-way flow Valve Washers quick connector
One-way flow Valve Washersquick connector is used in automotive fuel tank filler systems to interconnect the fuel filler tube with the fuel tank without the use of tools or special equipment. The quick connector includes a check valve to establish a substantially hermetic seal between the tank and the environment at all times to prevent the escape of liquid fuel during the refueling process as well as the escape of toxic vapors. A bypass vent operates during the refueling process to draw any vapors escaping from the tank or entering through the fuel fill tube inlet, filtering and returning them to the fuel tank.
Quick connect couplings have been widely used in the U.S. automobile industry for many years. Although applicable in numerous applications, quick connectors are most typically employed in fuel delivery systems and vapor recovery systems. The simplest and most cost effective design is the plastic housing female type quick connector releasably mated to a metal male tube end form. The opposite end of the female housing most typically defines a stem having a number of axially spaced barbs formed on the outer circumferential surface thereof and a nylon or resilient plastic tubing end form pressed thereover. Such an arrangement is described in U.S. Pat. No. 5,542,712, issued Aug. 6, 1996, entitled "Quick Connector Housing With Elongated Barb Design".
In the selected embodiment inside the invention, the Valve Washers consists of a valve member disposed for displacement inside the by means of passage in between a closed placement wherein the valve member contacts a repaired valve seat to an available placement to create available discussion therethrough. Furthermore, the valve member attributes a contoured impingement surface area which faces the fuel inlet accomplish inside the fast connector. This arrangement has the benefit of sealing the fuel tank to refrain from escape of fluid fuel or vapors in any way instances except once the tank is getting actively filled. When fuel flows by means of the flow tube, it impacts the valve member impingement surface, shifting it toward the available placement momentarily after which resealing the tank after the refueling treatment is complete. According to one more element inside the invention, the fast connector consists of information signifies which refrain from relative lateral and rotationally displacement inside the valve member since it traverses in between its available and closed positions. This prevents jamming or malfunctioning inside the confirm Valve Washers.
