Patent ID: 7341132

Claim:
A damper comprising a) a substantially tubular casing ( 8 ; 8 a ) which has a central longitudinal axis ( 9 ) and an end ( 24 ; 24 a ) on the side of a tappet ( 17 ; 17 a ) and a free end ( 10 ; 10 a ); b) the tappet ( 17 ; 17 a ) which is displaceably guided in the casing ( 8 ; 8 a ) and projects from the end ( 10 ; 10 a ) on the side of the tappet ( 17 ; 17 a ), having a central longitudinal axis ( 18 ) and an end ( 23 ; 23 a ) inside the casing ( 8 ; 8 a ) and a free end ( 19 ; 19 a ); c) fastening elements ( 12 , 20 ; 12 a , 20 a ) which are mounted on the free end ( 10 ; 10 a ) of the casing ( 8 ; 8 a ) and on the free end ( 19 ; 19 a ) of the tappet ( 17 ; 17 a ); d) a frictional damping unit ( 26 ; 26 a ) for producing a given frictional damping effect between the casing ( 8 ; 8 a ) and the tappet ( 17 ; 17 a ); and e) a guiding damping unit ( 41 c ; 41 d ) for damping and centering any deflection of the tappet ( 17 ; 17 a ) crosswise of the central longitudinal axis ( 9 ) of the casing ( 8 ; 8 a ), f) wherein the guiding damping unit ( 41 c ; 41 d ) is composed of several damping elements ( 50 c ; 50 d ) of annular arrangement, relative to the central longitudinal axis ( 18 ), g) wherein each damping element ( 50 ; 50 d ) possesses at least one curved rib portion ( 51 c , 53 c ; 52 d , 53 d ) which is flexibly movable radially of the central longitudinal axis ( 9 , 18 ), and h) wherein at least one rib portion ( 51 c ; 52 d ) is of two-piece design, producing a gap ( 72 ; 72 d ).
