  • Patent number: 9410522
    Abstract: A pressure control valve for a high-pressure accumulator of an injection device of an internal combustion engine, includes a magnetic actuator. The magnetic actuator has a magnetic core with contacting pins and a magnetic armature with an armature plate. The contacting pins pass through feedthroughs formed in the armature plate. The armature plate is hydraulically connected by a pressure equalization channel to a valve chamber connected to low pressure. The pressure equalization channel has an opening on the magnetic core end face which opens into the armature space. At least one of the feedthroughs forms a passage for the fuel through the armature plate for the pressure equalization. A residual air gap disk is arranged between the magnetic core and the armature plate. The residual air gap disk forms an additional feedthrough with a radial extension that extends in the direction of the opening.

  • Patent number: 7331359
    Abstract: A fluid control valve has at its lower inlet end a bi-loading seal. The seal is generally ring shaped in top view. However, it has a first flexible load section for sealing the stationary disk with respect to the housing and a second load section having an annular insert that in cross-section is hook-shaped to form a bend of more than 90 degrees. The insert can be molded within the resilient body of the seal so that its outer rim is disposed at a circular shoulder that bears against a seal stop of the housing. A high load can thus be applied between the bearing shoulder and seal stop to achieve a tight seal, while a lower load can be applied between the flexible, unrigidified part of the seal and a stationary valve disk.

    Abstract: The invention relates to a screw-in valve comprising a screw-in component, a sleeve with at least two connection openings to which a pressure load can be alternately applied, and a valve piston held for axial displacement in the sleeve for opening and closing a flow connection between the connection openings. In order to further develop the screw-in valve so as to reduce the risk of impairing movement of the valve piston on account of misalignment of the screw-in component, it is proposed, in accordance with the invention, that the sleeve be mounted so as to be axially immovable but displaceable and/or pivotable perpendicularly to the screw-in direction of the screw-in component relative to the screw-in component.

  • Patent number: 6964280
    Abstract: A combination check valve and pressure relief valve is provided for use in regulating the flow of fluid between a first fluid side and a second fluid side. The combination check valve and pressure relief valve includes a valve plug, a valve guide moveably positioned in relation to the valve plug, a valve stem engaged to the valve guide, a check compression spring attached to the valve stem and positioned between the valve guide and the valve plug, a valve seat carried by the valve stem, and a relief compression spring positioned between the valve seat and the valve guide. The valve guide is adapted to move the valve stem relative to the valve seat against the force of the relief compression spring to allow fluid to pass from the first fluid side to the second fluid side through a fluid flow passage formed between the valve stem and the valve seat.

  • Patent number: 6957660
    Abstract: A pressure relief valve has a valve element that is biased by a spring into a closed position. A pressure being controlled is applied to the valve element to counter the force of the spring. When the pressure applied to the valve element exceeds the force of the spring the pressure relief opens, otherwise the valve closes. The pressure is applied through a damping orifice which controls the rate at which the applied pressure can increase and decrease thus delaying the response of the pressure relief valve to pressure changes in both directions. The relative size relationship between the inlet and outlet can be varied to define the pressure-flow characteristic of the pressure relief valve.

  • Patent number: 6883538
    Abstract: A flow control valve coupling structure that does not require complicated machining and facilitates the installation of a flow control valve. The coupling structure includes a fitting portion having a male thread that is formed on a peripheral surface of the flow control valve. A coupled member has a coupling hole to receive the flow control valve. A cylindrical elastic sealing member is engaged with the coupling hole to seal the space between the flow control valve and the coupling hole. The elastic sealing member has an inner surface defining a mounting hole in which the fitting portion is fitted. A female thread is formed on the inner surface and is mated with the male thread of the fitting portion.

  • Patent number: 6736161
    Abstract: The invention relates to a pressure regulating valve comprising a valve body having one or more inlet openings and one or more outlet openings for a pressurized medium, an internal cavity connecting said inlet and outlet openings and a piston which is in contact with a valve seat between inlet and outlet and is axially slidable in the cavity in the valve body against a spring, which biases the piston to a closed position, whereby the valve opens when a predetermined pressure acts on the piston. The valve body is provided with an opening at its outlet side, where the cross-section of the opening is smaller that the cross-section of the cavity and which opening is in connection with a volume limited by the piston and the lower section of the internal cavity, whereby the pressure drop across the valve dampens variations in the volume.
