Abstract

Dampening assembly (100, 200, 300, 400, 500) comprising a first tubular element (21) coaxially inserted into a second tubular element (23) along an insertion path that ends at an end position. In the end position an abutting face (25) of the first tubular element (21) abuts a landing face (27) of the second tubular element (23). A displacement aperture (50) is adapted to guide liquid out from a liquid compartment (28) which is arranged between the first and second tubular elements (21, 23), during insertion of the first tubular element (21). The area of the displacement aperture (50) exhibits a reduced size, the closer the first tubular element (21) is to said end position.
