Abstract

In the illustrative embodiments described, a double tube shock absorber is provided with a continuously open throttling fluid passage device both on the piston valve unit and the bottom valve unit. The continuously open fluid passage device comprises a fluid passage chamber defined by a first wall member and a second wall member. The fluid passage chamber is connected to a first fluid chamber of the shock absorber by a first axially directed opening and to a second fluid chamber of the shock absorber by a second radially directed opening. The second radially directed opening is located radially outward of said first opening. The axial height of the fluid passage chamber continuously decreases in radial direction between said first opening and said second opening.
