A check valve for connection in a fuel tank filler tube. The valve has a tubular body with a plurality of radially inwardly extending projections on the inner surface of the tubular body or mounting adaptor. A valve seat is disposed downstream of the ribs, and an aperture is formed in the side of the tubular body. When the end of a siphoning hose is inserted into the check valve, the projections deflect the hose through the aperture to facilitate further insertion of the hose into the tank.

Siphonable check valve and method of making same

A fuel filler tube assembly including a one-way valve or check valve. The tube assembly is adaptable for pre-assembly on either a metal or plastic fuel tank and employs a common check valve with an adapter tube for plastic tanks. The valve employs a flapper with spaced ribs for deflecting a siphon hose away from the valve seal; and, the ribs are spaced to maintain the flow stream of he fuel during refueling and facilitating opening of the flapper.

Assembling a siphonable filler tube with a check valve on a fuel tank

A check valve for connection in a fuel tank filler tube. The valve has a tubular body with a plurality of radially inwardly extending vanes or ribs 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 and poppet with a tapered surface are disposed downstream of the ribs, clearance apertures 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.
