  • Patent number: 6701952
    Abstract: A valve (30) fitted within a fluid tank, the valve comprising a housing fitted with one or more fluid inlet ports, and an outlet port. The housing accommodates a float-type valve member (32) axially displaceable within the housing responsive to fluid level within the tank, between an open position in which the outlet port (58) is open, and a closed position in which the outlet port is sealingly closed. The housing is integrally formed with a nozzle member (60) being in flow communication with the outlet port and having a main portion with an outlet thereof extending within the tank.

  • Patent number: 6688330
    Abstract: A valve (10) for a fluid tank, comprising a housing formed with one or more inlet (28) and outlet (20) ports, side walls and a seating wall (14) portion supporting a float-type valve member. The valve member is axially displaceable within the housing responsive to fluid level within the tank, between an uppermost position and a lowermost position, and has a top and a bottom end and a bearing portion facing the seating wall portion of the housing. Either one or both of the seating wall portion of the housing and the bearing portion of the valve member, are fitted with one or more dampening members (46) for diminishing impacting noise of the valve member encountering the housing upon displacement into the lowermost position.

  • 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.
