  • Patent number: 8151952
    Abstract: The invention relates to a proportional control valve for the variable hydraulic adjustment of the damping force of a shock absorber, for which purpose the proportional control valve has a throttle function which can be set by varying the strength I of the electric current. The invention provides that on the basis of an instantaneous level of the electrical current Iist the proportional control valve is first closed by increasing the current to a maximum current strength Imax for a short time period toverdrive in order to change the damping force F, and the proportional control valve is then opened again by reducing the current strength I to a defined average current strength I in which the proportional valve assumes an intermediate position which results in a volume flow Q which corresponds to the desired change in the damping force F.

  • Patent number: 6851659
    Abstract: The present invention relates to a closure device, in particular for closing ducts in a valve-accommodating member in which pressure medium is conveyed, comprising a rotationally symmetric closure member that is wedged in an accommodating bore of a housing. The calked joint is configured as a calking cone so that the accommodating bore forms a funnel-shaped contraction in the direction of the closure member, said contraction covering the periphery of the closure member in the area of a collar, and succeeding the calking cone is a second housing step that is expanded in relation to the first housing step, said step being formed by the housing material deforming plastically to the funnel-shaped contraction of the accommodating bore.

    Abstract: The present invention relates to a closure device, in particular for closing ducts in a valve-accommodating member in which pressure medium is conveyed, comprising a rotationally symmetric closure member [(3)] that is wedged in an accommodating bore [(2)] of a housing [(11)]. The calked joint is configured as a calking cone [(1)] so that the accommodating bore [(2)] forms a funnel-shaped contraction in the direction of the closure member [(3)], said contraction covering the periphery of the closure member [(3)] in the area of a collar [(4)], and succeeding the calking cone [(1)] is a second housing step [(6)] that is expanded in relation to the first housing step [(5)], said step [(6)] being formed by the housing material deforming plastically to the funnel-shaped contraction of the accommodating bore [(2)].
