Devices and methods for a mechanical automatic shut-off to fluid reservoirs

摘要

Embodiments are provided for an automatic fluid shut off device having a float disposed in a fluid catch basin attached to a first end of a rod movable in a direction of rising fluid in the catch basin; a second rod end extending to a fluid supply base and terminating adjacent to a restrained latch arm end, the latch arm end configured to be pivotably displaceable upon a force by the second rod end in response to a rising fluid in the catch basin; the latch arm pivotably connected to a shut-off valve; and the shut off valve retained in an open position while the latch arm is restrained, and under a rotational force to close the shut-off valve upon a release of the latch arm in response to the force by the second rod end. The latch arm can be restrained by a latch arm retention notch extending downward and inward.

主权项

1. An automatic fluid shut off device, comprising:
a float disposed in a fluid catch basin attached to a first end of a rod movable in a direction of rising fluid in the catch basin; a second rod end of the movable rod extending into a bore of an actuation assembly having a fluid supply base; the second rod end terminating adjacent to a restrained latch arm end of the actuation assembly; the latch arm end configured to be pivotably displaceable upon a force by the second rod end in response to a rising fluid in the catch basin; the latch arm pivotably connected to a handle of the actuation assembly turnable on an axis to cause a shut-off valve to rotate to an open and closed position; and the shut off valve retained in an open position while the latch arm is restrained, and under a rotational force to close the shut-off valve upon a release of the latch arm in response to the force by the second rod end.
