  • Patent number: 12081081
    Abstract: In order to provide a method by means of which stacks of laminations can be produced in a simple and efficient manner, it is provided that the method comprises the following: coating one or more laminations with a bonding agent; bonding a plurality of laminations to form a sheet metal laminate by means of a first activation of the bonding agent; dividing the sheet metal laminate to produce a plurality of sheet metal laminate units and/or separating out a plurality of sheet metal laminate units from the sheet metal laminate; and bonding the plurality of sheet metal laminate units to form a stack of laminations by means of a second activation of the bonding agent, one or more parameters differing from one another in the first activation and the second activation.

  • Publication number: 20220271635
    Abstract: To provide a method by means of which stacks of metal sheets can be produced in an easy and efficient way, it is proposed that the method comprises the following: coating one or more metal sheets with a bonding substance; bonding multiple metal sheets to form a sheet-metal laminate by a first activation of the bonding substance; cutting up the sheet-metal laminate to produce multiple sheet-metal laminate units and/or cutting out multiple sheet-metal laminate units from the sheet-metal laminate; and bonding the multiple sheet-metal laminate units to form a stack of metal sheets by a second activation of the bonding substance, wherein the bonding substance comprises a resin material and an elastomer material.

  • Publication number: 20220243688
    Abstract: A valve device for exhaust gas recirculation in the exhaust gas system of a motor vehicle that is driven by an internal combustion engine. In order to create a valve device that can be used as an EGR check valve in which a pressure loss relative to known designs is reduced even with small valve geometries, it is proposed for the valve device to comprise a valve body that is embodied as a separate part that is mushroom-shaped or umbrella-shaped and is axially guided in a supporting plate in a region through which the gas flows axial, rests with its umbrella against the supporting plate in a way that seals the region through which the gas flows in a closed position, and has an end stop for an open position.

  • Publication number: 20210348542
    Abstract: In order to improve a sealing system, particularly for sealing against hot gas, it is proposed that it comprise a sealing element or a plurality of sealing elements and a support device for the sealing element or for the sealing elements, wherein the sealing system is constructed such that the one or at least one sealing element is arranged on the support device with play in at least one sealing state of the sealing system.

  • Publication number: 20190264640
    Abstract: A sieve seal as a component embodied of one piece, consisting of a seal, which holds a sieve body so that it is enclosed over an inner free cross-sectional area. The present invention also relates to a method for sustained operation of a sieve seal of this kind. In order to provide a remedy in the event of a clogging and/or soot formation and an accumulation of deposits in the sieve seal, it is proposed that the sieve body is embodied for an electric current to flow through at least part of it in such a way that a temperature that is sufficient to eliminate at least significant parts of the deposits is achieved or a corresponding temperature threshold is exceeded.

  • Publication number: 20100253008
    Abstract: A sealing arrangement for sealing of connecting sites (5) on flow paths (7) for flowable media, in particular for hot gases such as exhaust gases of internal combustion engines, with a sealing body (19) which adjoins the sealing surfaces (15, 17) of the connection sites (5) under a sealing force, is characterized in that a control body (25) is assigned to the sealing body (19) and is mechanically and thermally coupled to the sealing body (19) and to the surface regions (1, 3) on the connection sites (5) of the flow path (7) and transfers the sealing body (19) under thermal load into a state which produces an increased sealing force.

  • Publication number: 20100090417
    Abstract: The invention relates to a sealing arrangement for connections on lines conducting hot gases, particularly exhaust gas lines on internal combustion engines, having at least one sealing element (9) closing a gas channel relative to the outer side thereof in a gas-tight manner, characterized in that the sealing arrangement (1) comprises a means (13, 15, 21) for reducing the thermal load of the sealing element (9).
