Embodiment Construction

[0024] Such as figure 2 As can be seen in the figure, the fuel system exhaust valve 7 according to the present invention includes a housing 8 and a float 10 located in the housing 8 , and the housing 8 has a first opening 9 located in the upper part of the housing 8 . The float 10 is movable between a first position in which the valve 7 is open and a second position in which the float 10 covers the opening 9 so that the Said valve 7 is closed (as figure 2 shown). Said housing 8 also comprises several openings (not shown) at least on the sides of said housing 8 . Said valve 7 also comprises a liquid collector 11 arranged above said housing 8 so as to cover said first opening 9 . Said liquid collector 11 comprises its own housing 12 in which is arranged a peripheral wall 13 surrounding said first opening 9 . The peripheral wall 13 is arranged at a distance from the housing 12 of the liquid collector 11 so that a first volume space 14 inside the wall 13 and a second volume ...

Abstract

A fuel system exhaust valve (7), comprising a housing (8) having a first opening (9) at its upper part and a float (10) inside the housing. The float is movable between a first position in which the valve is open and a second position in which the float covers the opening (9) so that the valve is closed. The housing (8) also includes several openings at least on its sides. The valve also includes a liquid collector (11) located above the housing to cover the first opening (9). A peripheral wall (13) surrounding the first opening (9) is arranged in the housing (12) of the liquid collector, the peripheral wall (13) being at a distance from the liquid collector housing (12) to create a first The volume (14) and the second volume (15) outside the wall (13). The first volume is larger than the second volume and they are connected by at least one gap (16) between the top of the wall (13) and the top of the collector housing (12). The liquid collector housing (12) also includes a discharge port (17) directly connected to the second volume space.

Description

technical field [0001] The present invention relates to a fuel system exhaust valve comprising a housing and a float within said housing, said housing having a first opening in an upper portion of said housing, wherein said float is in a first position and a second Movable between two positions, in the first position, the valve is open, in the second position, the float covers the opening so that the valve is closed, and the housing also includes at least Several openings on the side of the housing. Background technique [0002] Some vehicles are difficult or slow to fill up with fuel. It usually manifests itself as the gasoline pump shuts off repeatedly after adding only a small volume of gasoline when refueling. Fuel backed up into the filler pipe, causing the automatic shutoff on said pump to activate. The fuel gradually falls in the neck of the filler tube, and some more gasoline can be added before it is closed again. [0003] There are generally two possibilities f...
