Damping force controlling shock absorber

Abstract

A damping force variable shock absorber of the present disclosure is disclosed. The damping force variable shock absorber includes a cylinder having an inner tube and an outer tube filled with a fluid, a housing coupled to a lower end of a piston rod located inside of the inner tube and forming a connection passage therein, a magnet member provided inside the housing, a plunger moving by magnetic force of the magnet member, a first piston valve coupled to the outside of the housing to divide a compression chamber from a rebound chamber, and a second piston valve provided in the housing, wherein the connection passage is provided such that at least a part of the fluid flowing toward the first piston valve is bypassed to the second piston valve side by the opening and closing of the plunger.

Dependencies are inferred from the claim text.
