  • Patent number: 5740842
    Abstract: A fuel tank arrangement for a motor vehicle. The arrangement includes a fuel tank containing fuel therein and having a gas space disposed above the fuel, and a venting device connected to the fuel tank. The venting device includes an activated charcoal filter and a venting conduit connecting the gas space to the activated charcoal filter for establishing gas communication therebetween. A stop valve is disposed in the venting conduit and is adapted to open gas communication between the gas space and the activated charcoal filter during refueling. Moreover, a fuel separator is disposed in the venting conduit for separating fuel from a gas flow through the venting conduit thereby yielding separated fuel.

  • Patent number: 5094262
    Abstract: A regulator with a hysteresis-affected characteristic curve has a manually operable actuating element for presetting a desired control variable, an axially displaceable control slide for adjusting the preset control variable and a control incline which is coupled to the actuating element. The control incline converts, by means of a rising control face, the adjustment movement of the actuating element into a axial displacement of the control slide. For the purpose of compensating the hysteresis when adjusting a control a variable such that the same control variable is brought about by rotating the actuating element to the left or to the right into the same setting, the control incline bears a toothing along its control face. Each tooth has, in two planes which extend along the displacement direction of the control face and are perpendicular to one another, a sawtooth-like contour with in each case a rising edge for running up the control slide and a falling edge which follows in the displacement direction.

  • Patent number: 5092358
    Abstract: A pressure regulator whose initial pressure can be set by manually setting the initial stress of a control spring has a double-seated valve with an inner and outer valve seat and a valve closing element. The valve closing element divides a supply pressure chamber from a control pressure chamber and the latter from a pressure-relief chamber. The inner valve seat is arranged on a control piston which is loaded by the control spring. In order to set a higher initial pressure, the initial stress of the control spring is increased, in order to reduce pressure, the initial stress of the spring is diminished. During this process, the outer or inner valve seat lifts off temporarily from the valve closing element until equilibrium is reestablished by a corresponding pressure chamber and the double-seated valve closes.

  • Patent number: 4567994
    Abstract: A closure assembly for a container includes a filler nipple formed on the container and having an inner wall provided with a depression, a plug unit and an operating lever pivotally supported on the plug unit, and a sealing ring received in a groove of the plug unit. The sealing ring has a radially outwardly expanded sealing state and a relaxed, non-sealing state. A sealing ring actuating device is operatively connected to the sealing ring and the operating lever for moving the sealing ring from one state to another upon movement of the operating lever between an intermediate position and a closed position. A locking bolt arrangement is supported in the plug unit and has an advanced, locking state and a withdrawn, unlocking state.
