  • Patent number: 7575218
    Abstract: The invention relates to a magnet valve, having a valve insert and a tappet guided movably in the valve insert via a tappet guide, which tappet is braced on a valve body via a restoring spring resting a contact face of the tappet, and the restoring spring is guided radially from inside on one end by a spring guide of the tappet, the spring guide adjoining the contact face. According to the invention, centering means are present, which are disposed on the tappet in such a way that the restoring spring is centered and radially guided from inside over a substantial portion of its length.

  • Patent number: 7243899
    Abstract: An electromagnetic valve arrangement with a valve element having least one part disposed in a valve chamber defined by a valve insert in the region of a valve seat. An end facing away from the valve chamber of the valve element is operatively connected to an armature and end face of the armature facing toward the valve insert and/or an end face of the valve insert facing toward the end face of the armature is embodied with a surface profile such that a flow cross section, defined by the opposed end faces varies at least regionally in the radial direction and/or in the circumferential direction of the armature.

  • Publication number: 20050287515
    Abstract: This invention discloses methods and devices useful for eliminating or reducing the adverse effects associated with the use of a variety of therapeutic fluids. It is proposed herein that the source of such side effects (e.g. fever and septic shock) is the oligonucleotides present in the fluid and that using the ultrafiltration and adsorption methods and devices disclosed in the invention one can minimize the risk of these adverse effects often associated with dialysis treatment.

  • Patent number: 6382250
    Abstract: A solenoid valve useful in a slip-controlled hydraulic brake system of a motor vehicle, and which has a seat valve disposed between a pressure fluid inlet and a pressure fluid outlet and in the bypass to this seat valve, has a check valve with a hollow conical valve seat and a closing body, which has a section that is embodied as complementary to the hollow conical valve seat. A rubber-elastic sealing ring is accommodated with the greater portion of its cross section in the circumference of the section and in the closed position of the check valve, this sealing ring can compensate for dimensional deviations of the valve seat at low pressures.
