<p>A check valve (10) for connection in a fuel tank filler tube. The valve has a tubular body (12) with a plurality of radially inwardly extending vanes or ribs (20) in the inlet end about a portion of the circumference. The ribs are tapered in the flow direction to deflect the end of a siphoning hose to an offset opening. A valve seat (24) and poppet (26) with a tapered surface (36) are disposed downstream of the ribs, clearance apertures (18) are formed in the side of the tubular body downstream of the valve seat. The tapered surface of the poppet, upon being opened by insertion of the end of a siphoning hose deflects the hose outwardly through the clearance apertures to facilitate further insertion into the tank. The poppet is biased normally closed by a spring (28).</p> |
