Patent ID: 8240439

Claim:
A vehicle damper of variable damping force, comprising: a tubular cylinder for accommodating damper oil; a piston slidably housed in the cylinder and dividing the cylinder into two chambers; a pair of disk-shaped valves for controlling flow of the damper oil between the two chambers in correspondence with sliding movements of the piston; and an electromagnetic solenoid provided in the piston for open/close-driving the valves, wherein the valves have opening/closing parts for opening and closing a plurality of ports formed in the piston, and supporting parts for supporting the opening/closing parts in such a manner as to allow the opening/closing parts to make opening and closing actions, and wherein the opening/closing parts are disposed on a semi-circular opening/closing part side of each valve and the supporting parts are disposed on a semi-circular supporting part side of each valve with the opening/closing part side being disposed on opposite sides of a straight line passing diametrically across the piston, and wherein the supporting part side of each valve of the pair of valves includes an inflow hole aligned with one of the plurality of ports, and the opening/closing part of each valve is aligned with a different port from the port aligned with the inflow hole.
