  • Patent number: 10598243
    Abstract: A spring carrier comprising a casing tube having a longitudinal axis; a spring plate, a base plate and a spring disposed inside the casing tube between an upper and a lower boundary element; the lower boundary element having a projection arrangement having retaining projections disposed on the casing tube; the base plate having a recess arrangement on an outer surface facing the casing tube; wherein the projection arrangement and the recess arrangement are arranged such that, in a mounting situation, all the retaining projections are disposed next to the base plate and, in an operational situation, the projection arrangement overlaps with the base plate, wherein a locking projection is disposed inside the casing tube and the base plate has locking recesses facing the casing tube, wherein the locking projection is disposed inside a first locking recess in the mounting situation and a second locking recess in the operational situation.

  • 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: 10184538
    Abstract: A telescopable spring support which comprises a housing, a pressure plate, a load pipe, and a pressure spring and which is designed to elastically support components in a load direction. The housing has a stand side and an upper side, and the pressure plate is arranged in the housing and can be moved within the housing in the load direction. The pressure spring is arranged between the pressure plate and the stand side and applies a spring force to the pressure plate, said spring force being directed towards the upper side in the load direction. The load pipe is connected to the pressure plate and, in each position of the pressure plate, extends outwards from the interior of the housing through an opening arranged on the upper side of the housing. The housing comprises a stand housing and a movable housing. The movable housing can be moved towards the stand housing in the load direction, wherein the stand housing has a stand side, and the movable housing has the opening.

  • Patent number: 9512942
    Abstract: A cold-insulated pipe support for a pipeline comprising a receiving space for a pipe portion, a heat insulating layer of solid insulating material, that surrounds the receiving space, an outer protective casing, a vapor barrier arranged between the heat insulating layer and the outer protective casing, two part-circular support shells The support shells are of a shorter configuration at both support ends in the axial direction than the other support portions, wherein there remains a free support portion. Provided in the region of the free support portions at the two ends are contact elements which bear directly against the ends of the support shells. The contact elements are fixed by means of radially screwed-in headed screws which are anchored through the protective casing and the vapor barrier in the solid heat insulating layer.
