초록 ▼

A roll-over vent valve for an automobile fuel tank comprises a novel means for minimizing the force required to re-open a corked shut-off element. The disclosed embodiment comprises a thin, slightly pliable, circular disc for the shut-off element which seats against an annular seat to close the vent passage in the event of roll-over. If the pressure in the tank headspace is sufficiently positive and the disc is closed against the seat in the absence of roll-over, an extra force is required to unseat the disc because of the pressure differential acting on the seated disc. The magnitude of force required to unseat the disc is significantly attenuated in the present invention by having the force act over a limited circumferential extent of the sealing contact of the disc against the seat. This peels the disc from the seat with complete unseating being accomplished by causing the force to act progressively around the perimeter of the disc. In one embodiment the disc is caged by a set of fingers which sequentially act on the disc at different circumferential locations to transmit the re-opening force around the disc. In another embodiment tethered cords of different lengths are used.

A roll-over valve comprising a valve body having an axis adapted to be disposed in a nominally upright attitude, said valve body having an inlet adapted to be communicated to the headspace of a tank for a volatile combustible liquid, such as gasoline or diesel fuel, and an outlet adapted to be communicated to a point which is external to the headspace of the tank, a pasasge through which flow between said inlet and said outlet is constrained to pass, an attitude and fuel level-responsive mechanism for selectively opening and closing said passage in accordance with the actual attitude of the roll-over valve body relative to nominal upright and with fuel level, said mechanism comprising a shut-off element which is movable into and out of sealing contact with an annular seat formed in said valve body and extending around said axis for opening and closing said passage, and gravity-responsive means which acts to keep the shut-off element unseated from said seat when the actual attitude of the valve body is within a certain limited range of attitudes about and including nominal upright and the fuel level is below a certain level, but which moves the shut-off element against the seat to close the passage when the actual attitude of the valve is outside said limited range or the fuel level is above said certain level, said gravity-responsive means comprising means which, in response to conditions of attitude and fuel level that are conducive to movement of said gravity-responsive means in a direction for unseating said shut-off element from said seat while the shut-off element is disposed against said seat and forced against said seat by a certain vapor pressure differential, applies to said shut-off element an unseating force which is concentrated along a limited circumferential segment of the full extent of circumferential sealing contact of the disc with the seat, which is due to the net effect of gravity along acting on said gravity-responsive means, and which is sufficient by itself to displace said shut-off element from sealing contact with said seat.
