Patent ID: 8640837

Claim:
A damper with a) a housing having a central longitudinal axis, at least partially encompassing a housing interior by housing walls, the housing walls comprising two longitudinal walls and two side walls connecting the two longitudinal walls to form a rectangular recess, b) a plunger displaceable in the housing along the central longitudinal axis, guided out of the housing and having at least one friction lining recess, wherein the friction lining recess fully penetrates the plunger and has four recess walls comprising two longitudinal recess walls and two recess side walls connecting the two longitudinal recess walls to form a four-sided recess, and c) fastening elements, arranged at free ends of the housing and the plunger, and d) a friction lining, arranged in the at least one friction lining recess and in direct and frictional contact with the two longitudinal recess walls and the two recess side walls, wherein said friction lining is unitary and formed of one friction material, wherein only a single friction lining is required for friction on two friction surfaces of the two opposite longitudinal walls, and e) wherein the shape of the friction lining is matched to the shape of the friction lining recess.
