Vehicle refueling valve

A fuel vapor vent assembly adapted to be mounted in the top of a motor vehicle fuel tank, said assembly comprising a body having an entry passage adapted to be open to liquid fuel and fuel vapor and a vapor exit passage adapted to be connected to a fuel vapor storage device and the body being connected to the top of a fuel tank in depending relationship therewith;

• a valve and said valve including a float and a valving element carried by the float and tiltable with respect to the float for compensating for tilt further characterized by:
• said body further including a vapor inlet passage located above said entry passage;
• a first tubular member supported within said body having one end sealing connected to the vapor exit passage and having an opposite end defining a valve seat closable by the valving element and located below said vapor inlet passage for separating liquid fuel particles prior to entering said vapor exit passage;
• a cover member connected to and outboard of the upper wall of the fuel tank;
• said cover member forming said vapor outlet passage and said body including a second elongated tubular member connected to said cover member inboard of said fuel tank and said vapor inlet passages being formed in said second elongated tubular member adjacent the upper wall of the fuel tank, and
• a baffle ring connected to said body below said vapor inlet passage and spaced from said first tubular member for trapping liquid fuel particles at said vapor inlet passage for return to the fuel tank through the vapor inlet passage so as to prevent the fuel tank through the vapor inlet passage so as to prevent passage thereof through the first tubular member and out said vapor exit passage.

• a cover member connected to and outboard of the upper wall of the fuel tank;
• said cover member forming said vapor outlet passage and said body including a second elongated tubular member connected to said cover member inboard of said fuel tank and said vapor inlet passages being formed in said second elongated tubular member adjacent the upper wall of the fuel tank, and
• a third tubular member having a height less than that of said first tubular member and located laterally thereof and including a vent therein in communication with said vapor outlet passage and a float within said third tubular member for closing said vent in response to tilt to prevent escape of liquid fuel from the fuel tank through said vent.

• a first tubular member supported within said body having one end sealingly connected to the vapor exit passage and having an opposite end defining an annular valve seat closable by the valving element and located below said vapor inlet passage for separating liquid fuel particles prior to entering said vapor exit passage;
• and
• said valving element having an annular skirt and a ball joint thereon located concentrically of said annular skirt;
• said float having a ball connected on one end thereof for adjusting the position of said valving element with respect to said annular valve seat to compensate for tilt.

• and
• a pressure transducer mounted on said body and a vent passage formed in said body communicating said pressure transducer with said vapor outlet passage.
