Abstract:
1. A valve comprising a housing having an interior, an open bottom and a liquid inlet, a shut-off lever supported in said housing for pivotal movement about a first axis between a first closed position, a second open position and a third seeping position, said shut-off lever having a cam surface, a closure supported on said shut-off lever and operable, when said shut-off lever is in the first closed position or between the first position and the third position, to prevent liquid from flowing through said liquid inlet, a baffle supported on said shut-off lever and operable, when struck by liquid flowing through said liquid inlet, to bias said shut-off lever to pivot towards said second open position, and a float lever supported in said housing for pivotal movement about a second axis between a first, upper, closed position, a second, lower, open position and a third seeping position, said float lever having a cam surface, wherein said float lever cam surface cooperates with said shut-off lever cam surface so that pivotal movement of said float lever from said second position to said third position causes pivotal movement of said shut-off lever from said second position to said third position.
