  • Patent number: 10781880
    Abstract: This invention relates to a damping device for mounting two separate components for damping oscillations between the components, wherein the damping device has an axial damper that comprises a first connecting element as well as a second connecting element, wherein the first connecting element is connected to the second connecting element via a damping section by ensuring an axial relative movement of the two connecting elements with respect to one another, wherein the damping section is designed for damping the axial relative movement between the connecting elements.

  • Patent number: 10598247
    Abstract: The invention relates to a valve to ensure pressure compensation between subchambers of a hydraulic damper, wherein the valve comprises a first side for connection to a first subchamber and a second side for connection to a second subchamber, the valve is designed to shut off in its rest position a flow of fluid between the two sides and comprises, when deflected from its rest position, a passage channel with a passage cross-section for admitting the flow of fluid, the valve comprises two valve elements guided towards each other and movable towards each other along a path of movement in a movement direction x, one of the two valve elements is designed as a moving element and the other valve element as a seat element, a pressure can be applied to the moving element, on the load side thereof, by a fluid coming from the first side, generating an effective force for moving the moving element in the moving direction x, and the moving element is connected to a spring system which applies to the moving element a spr

  • Patent number: 8251338
    Abstract: A constant bearer having a fastening part, a load-bearing part and a spring system which is arranged between the fastening part and the load-bearing part for generating a carrying force which remains constant over a carrying travel of the load-bearing part with respect to the fastening part, where the spring system has a suspension system for absorbing the load, a compensation device for compensating for changing spring forces of the suspension system over the carrying travel, and a prestressing device for setting a prestressing force of the suspension system.

  • Patent number: 7861983
    Abstract: The invention relates to a cold-insulated fixed-point pipe support for a low-temperature pipeline which includes an insulating system arranged between an outer shell and a supportable low-temperature pipeline having solid thermal insulating material which thermally insulates the pipeline from the low-temperature environment. A rotation-preventing and displacement-preventing device prevents rotation and displacement of the thermal insulating material with respect to the pipeline and an outer shell. A fixed-point pipe support is adapted to be fitted and removed in a substantially radial direction over the pipeline, and has at least one division with respect to shape with a division plane thereof extending perpendicular to a cross-sectional plane, and having a connecting device for releasable connecting and fixing shaped parts formed by the division.

  • Publication number: 20100108852
    Abstract: The invention relates to a constant bearer (1) for loads which are displaced, in particular for pipelines and the like, having a fastening part (2), a load-bearing part (3) and a spring system (4) which is arranged between the fastening part (2) and the load-bearing part (3) for generating a carrying force (T) which remains constant over a carrying travel of the load-bearing part with respect to the fastening part, where the spring system (4) has a suspension system (5) for absorbing the load, a compensation device (6) for compensating for changing spring forces of the suspension system (5) over the carrying travel (tw), and a prestressing device (7) for setting a prestressing force (V) of the suspension system (5).
