Abstract

603309 A float valve comprising: a valve body having a hole from an interior of the body to an exterior of the valve and a rim projecting about the hole and having at least one opening, a float arm pivotally coupled to the body adjacent the hole and adaptable to be coupled to a float at one end of the arm for pivoting the arm, and a sealing member associated with the float arm and moveable with the arm such that in a first pivotal position of the float arm the sealing member contacts the rim without closing the hole thereby enabling fluid to flow from the hole through the opening of the rim to the exterior of the valve, and further pivotal movement of the float arm to the closed position causes the sealing member to compress against the rim and move towards the hole to close a fluid passage between the hole and the opening and prevent fluid from flowing from the interior of the body to the exterior of the valve.
