摘要： A damper includes a damper housing, a fluid chamber in the damper housing, a damping fluid in the fluid chamber, a piston displaceable in the fluid chamber, a piston rod connected to the piston, and a volume compensating device in the damper housing. The volume compensating device compensates for a displaceable volume of the damping fluid when the piston rod is immersed into the fluid chamber, and includes a seal to seal the fluid chamber relative to the piston rod and/or relative to an inner wall of the damper housing, a support element to guide the seal, a spring element to reset the seal after a damping stroke at least partially into an initial position. The spring element, the seal, and/or the support element form a common compensating member having an integral one-piece configuration. The compensating member is configured to bear loosely against a cover for closing the damper housing.

摘要： An actuating arm drive for driving a movably mounted furniture part of a furniture item, includes at least one arrangement consisting of a compression spring and at least one guiding device for guiding the compression spring. The at least one guiding device has an at least partly variable diameter in order to compensate for a radial clearance between the compression spring and the guiding device, taking into account the change in diameter of the compression spring when the compression spring is loaded.
