A vapor vent valve (10) has an annular locking ring (26) received thereover, with surfaces (32) thereon engaging the valve for limited axial movement therebetween and preventing relative rotation therebetween. A fuel tank (12) has an access opening with a ...

A fuel vapor vent valve (14) is formed of different plastic material than the fuel tank (12). A U-shaped or cupped attachment member (36) formed of tank material is received over the valve (14) with the upper end (54) slotted to permit the hose fitting to ...

A fuel tank vapor vent system for a motor vehicle having a float operated vent valve in the tank top for permitting fuel vapor flow through a vapor conduit to a remote storage canister. A filler nozzle seal (32) in the tank filler neck (24) seals about the...

The float (32) has an elastomeric valve disk with an annular bead rim (48) caged for limited lost motion movement on the top of the float. A rigid backing plate (50) for the valve disk is pivoted on a curved surface (52) on the top of the float to ensure s...

The tank vent pipe (4) opens into the tank filler pipe (1) parallel and in the same direction as the fuel flow direction (3). The mouth opening of the vent pipe preferably surrounds in a ring the tank gun (2) inserted in the filler pipe. The pipe resistanc...

The system has a venting system controlled by valves (17,22,24) and blocked with the vehicle parked, whereby both the tank pressure and the correct positioning of a closure element (11) that hermetically seals the tank filler are monitored. An intended fil...

The surge protection element (10,11,11') is designed as a fixed component part with a multiple of individual ducts, having respectively a small diameter in relation to the balance opening. The surge protection prevents a penetration of fuel splashing about...

The device has pipes extending from the tank for operational and filling ventilation. The pipes (10,11) have neighboring or common walls in at least one area outside the fuel tank (1), or engage around each other. The outer walls of the pipes are mainly cy...

Ventilation device comprises an expansion tank in the fuel tank (1) and at least two ventilation lines (5, 9-11) opening into this expansion tank. The ventilation lines begin near at least one side wall (3) of the fuel tank and run toward an opposite side ...
