  • Connection ring for removable attachment of a fuel supply unit on a motor vehicle tank opening
    Patent number: 10697409
    Abstract: A connection ring is provided for removable attachment of a fuel supply unit on a fuel tank. The connection ring has a ring upper side, at least one attachment elevation which protrudes from the ring upper side, and at least one tool engagement region. The tool engagement region is constructed such that a torque from a tool can be transmitted onto the connection ring. At least one portion of the tool engagement region and one portion of the attachment elevation are at an equal distance from the center of the connection ring in the radial direction from the center.

  • Valve and fuel tank provided with a valve for a motor vehicle
    Patent number: 6581621
    Abstract: The invention relates to a valve and a fuel tank provided with a valve for a motor vehicle. Bleeder valves for integrated compensation volumes for fuel tanks are known in the prior art. One disadvantage of known valves is that if the tank is filled slowly during the refueling operation, the fuel compensation volume can fill. The invention aims to provide a valve with a compact construction. To this end a pressure valve (28) is located on the valve (1, 3) which opens if there is a predetermined excess pressure in the fuel tank (30), a refueling venting opening (38) is configured in the valve (1, 3) so that a sealing plate (5) can close the refueling venting opening. The sealing plate (5) has an operational venting opening (42), which can be closed by a displaceable closure element (15) that is displaced according to a position of a float (26) that is located on a float lever (24).
