ABSTRACT:
A hydraulic damper includes a cylinder receiving hydraulic liquid therein, a piston working in the cylinder and partitioning the interior thereof into two chambers, a piston rod secured to the piston and extending through one of the two chambers to the outside of the damper and having an axial bore extending therethrough, a valve mechanism mounted on the piston, an elongated adjusting rod axially displaceably disposed in the piston rod with the inner end thereof cooperating with an orifice member which is mounted on the piston rod, and a by-pass passage including the axial bore in the piston rod and an orifice of the orifice member and connecting the two chambers. The orifice member is axially adjustably mounted on the piston rod such that the location of the orifice member with respect to the piston rod can be adjusted to abut with the adjusting rod when the adjusting rod is at an innermost position.
