  • Over filling interdiction, vent and roll over valve
    Patent number: 6564821
    Abstract: An over filling and roll over valve includes a housing, in which a valve assembly is located. The valve assembly includes a first stage member and a second stage member, being coaxially and relatively displaceable within the housing. The first stage member has a slit-like aperture at a bottom and an outlet aperture at the top. The inlet and the outlet apertures are in flow communication. The second stage member is a float provided with a flexible membrane strip for closing the slit-like aperture of the first stage member. The valve assembly is provided with at least one anchoring member extending between the first stage member and the second stage member and permitting a limited freedom of relative movement therebetween in such a manner that displacement of the second stage member into its second position entails positive displacement of the first stage member into its second position.
