  • Patent number: 8322378
    Abstract: A check valve for one-way flow of a fluid comprises a valve body defining at least two pairs of axially-extending sidewalls, each pair of sidewalls having a pair of resilient lips defining slit opening at the outlet end of the valve. In one embodiment of the invention, the valve body defines three pairs of sidewalls and corresponding lips which are arranged one another so as to provide the check valve with an “I-beam” cross-sectional shape. The I-beam check valve has a compact cross-section, making it suitable for mounting either inside or outside a pipe. The I-beam shape provides support along the valve axis so that the valve does not require any supplemental support structure. In another embodiment, the valve body may define two pairs of sidewalls having a “T-shaped” transverse cross section.

  • Patent number: 8297298
    Abstract: In a vent control valve for a fuel tank, a housing receiving a float assembly therein is provided with a communication hole passed across a wall of the housing, and an opening of the communication hole facing an interior of the housing is directly exposed to an interior of the housing when the float assembly is in a low position and overlaps with a peripheral wall of the float assembly when the float assembly is in a high position. By suitably selecting the size of the communication hole and/or the number thereof, a desired delay in the dropping of the liquid fuel level in the housing following the filling up of the fuel tank can be achieved. Thereby, overfilling of the fuel tank can be avoided.

    Abstract: A valve for the control of a gas stream is provided with a valve housing enclosing a valve chamber. At least one pressure-sided inlet and at least one suction-sided outlet is provided with a valve opening between them to link them. An elastically movable control membrane is arranged at the valve housing which reduces or increases the flow cross section in the area of the at least one valve opening and/or opens or closes the at least one valve opening. A first device exerts a first further force on the control membrane in such a way that with an increasing pressure difference the further force exerted by the first device on the control membrane in opposite direction to the closure direction of the valve increases.

    Abstract: The present invention thus relates to a mounting device having a metallic base plate, on which multiple fastening elements are provided, from each of which at least a partial area projects above the base plate. The mounting device is obtainable by incising fastening element blanks into the surface of the metallic base plate while leaving one connection edge per blank in such a way that they each have a web-shaped base area, which comprises the connection edge on one end, and a head area adjoining the base area, which projects laterally beyond the neighboring base area on at least one side. At least one partial area of the blanks is bent out of the base plate around at least one bending edge located in the base area. The projecting edge of the head area adjoining the base area runs at an angle between 0° and 70° in relation to the plane of the base plate after the fastening elements are bent out of the base plate.
