  • Patent number: 10006561
    Abstract: An electromagnet of an electromagnetically actuated fluid valve includes a magnet core that receives a coil, and an armature unit that can be moved axially relative to the coil in the magnet core. The electromagnet further has a device for damping a stop of the armature unit against the magnet core. The device has a flow cross-section for a medium, the flow cross-section decreasing when the armature unit is moved. The cross-section can be formed by a cone that interacts with a counter surface.

  • Publication number: 20160305570
    Abstract: The invention relates to an electromagnetically actuated valve (1), comprising a valve piston (3) bearing a valve plate (2). A spring plate (14) is fastened to the valve piston (3), against which spring plate a valve spring (15) that moves the valve (1) into a closed position lies. The valve also comprises an electromagnet (16), which has a coil (18) and an armature (19) that is arranged on an armature pin (20). The armature pin (20) interacts with the valve piston (3) by means of a contact point. According to the invention, an electromagnetically actuated valve (1) is provided whose function is improved while a low level of structural complexity is attained. This is achieved in that the contact point has a diameter that is enlarged in relation to the diameter of the armature pin (20) and of the valve piston (3) and is planar. Thus, the contact pressure is reduced in this region.

  • Publication number: 20160305571
    Abstract: The invention relates to an electromagnet 1 of an electromagnetically actuated fluid valve 2. The electromagnet 1 has a magnet core 17 which receives a coil 18 and an armature unit 19 which can be moved axially to the coil 18 in the magnet core 17. The electromagnet further has a device for damping a stop of the armature unit 19 against the magnet core 17. According to the invention, an electromagnet 1 is provided which is permanently improved with respect to the noise emanating from said electromagnet. This is achieved in that the device has a flow cross-section 28 for a medium, said flow cross-section decreasing when the armature unit 19 is moved. The cross-section is formed by a cone 26 which interacts with a counter surface 27.

  • Patent number: 7422194
    Abstract: A solenoid valve, such as, for example, a tank-vent valve f or tank venting in motor vehicles, includes at least one valve orifice forming a sealing seat, and a valve member, which cooperates with the sealing seat for releasing and closing it, the valve member being stressed by at least one spring element and activated by an electromagnet. An essentially unstressed neutral position of at least one additional spring element, which acts upon the valve member in the activation direction, is provided in which the valve member is set apart from the sealing seat. In this manner, the impact of the valve member on the sealing seat, which may be accompanied by distracting noises and wear, is damped.

  • Patent number: 7147202
    Abstract: A canister-purge valve for the metered admixing of a fuel scavenged from a fuel tank of an internal combustion engine into the internal combustion engine includes a valve seat and a valve body movably located relative to the valve seat. A sealing element is provided on the side of the valve body facing the valve seat and a damping element is provided on the side of the valve body facing away from the valve seat. The sealing element (40) is made of a first elastomer and the damping element (41) is made of a second elastomer with different properties than the first elastomer.

  • Publication number: 20050269539
    Abstract: Known canister-purge valves have a valve seat and a valve body movably disposed on the valve seat with a sealing element and a damping element. The sealing element is located on a side of the valve body facing the valve seat, and the damping element is located on a side of the valve body facing away from the valve seat. The sealing element and the damping element are a single component and are composed of a single elastomer. In selecting the elastomer, a compromise must be struck between good sealing properties for the sealing element and good damping properties for the damping element. With the canister-purge valve according to the present invention, the function of the canister-purge valve is improved by providing the sealing element with very good sealing properties and providing the damping element with very good damping properties. According to the present invention, the sealing element (40) is made of a first elastomer and the damping element (41) is made of a second elastomer.

  • Publication number: 20040025851
    Abstract: With metered admixing of volatized fuel in an intake manifold of an internal combustion engine with a supercharger, the problem exists that depending on the respective operating state, different pressures prevail in the intake manifold. This problem is resolved in known devices, in that return valves are subsequently added and structurally separated from the tank aeration valve in the flow direction. The present invention proposes that the return valves (39, 40) are structurally integrated in a tank aeration valve (5), in order to reduce the assembly expense and the spatial requirements.

  • Patent number: 6651951
    Abstract: A magnet valve according to the related art has a sealing and damping device with an elastic region on which, during operation, a force acts due to different existing pressures that must also be overcome when the armature plate is moved. A magnet valve (1) designed according to the invention has a sealing and damping device (46) with an elastic region (105) that is oriented and designed in relation to a seal seat (103) in such a fashion that the above-described force is offset. As a result, a better characteristic curve of the magnet valve (1) over the existing differential pressure is obtained.

  • 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.
