  • Patent number: 6321725
    Abstract: A solenoid valve for tank ventilation in motor vehicles, comprising a magnetic yoke with at least one valve opening and with a cooperating spring-loaded valve member for opening and closing the at least one valve opening. The valve element constitutes a magnetic armature of an electromagnet and is disposed between the magnetic yoke of the electromagnet and a hollow, cylindrical magnet core of the electromagnet. A valve seat body which is separate from the magnetic yoke and contains the at least one valve opening is disposed in an axial opening in the magnetic yoke, and on a side remote from the valve member. The valve seat body rests against a housing wall of the solenoid valve by use of a support element made of a damping material.

  • Patent number: 6253789
    Abstract: A valve for metered introduction of fuel, volatilized from a fuel tank of an internal combustion engine, into the engine, having a valve housing which has an inflow neck for connection to a fuel tank or to an adsorption filter downstream of the tank for the volatilized fuel, and having an outflow neck for connection to the engine, having a valve member accommodated between the inflow neck and the outflow neck in the interior of the valve housing, which valve member is actuatable by an electromagnet that has a magnet core, and which cooperates with a valve seat embodied on a valve seat body, is characterized in that the valve housing includes a first housing part, closed on the inflow side by a protective screen, in/on which the electromagnet, the valve member, the valve seat body and the outflow neck are provided, and a second housing part, on which the inflow neck is disposed and which can be secured to the first housing part.

  • Patent number: 6149126
    Abstract: A fuel tank ventilation valve for a Laval nozzle, which has a sensitive regulation of the through flow quantity. The valve has a valve seat which is embodied on a valve seat body which has at least one opening that can be closed by the valve member. A cross section of the at least one opening is embodied as essentially smaller than an entry cross section of the Laval nozzle that is disposed spaced apart from the valve seat. The valve is suited for a metered introduction of fuel that has evaporated from a fuel tank of a mixture-compressing internal combustion engine with externally supplied ignition into an intake tube of the engine.
