Title:
SHOCK ABSORBER
Document Type and Number:
WIPO Patent Application WO/2013/122252
Kind Code:
A1
Abstract:
Provided is a shock absorber for which a large damping force is set when electrification is impossible. A damping force control valve (10) is arranged in a bypass of a damping force generator in a shock absorber (100). The damping force control valve (10) comprises a valve element (20) that reciprocates due to a solenoid (23), a first operating fluid chamber (30) provided with a port (30a), a second operating fluid chamber (40) that communicates with a channel (21), and a coil spring (35). The valve element (20) moves further away from the port (30a) and the volume of an attenuating medium flowing in the bypass increases in correspondence to a larger electrification amount on the solenoid (23). The valve element (20) moves to a position to block the port (30a) when the solenoid (23) is not electrified since a force on the valve element (20) toward the port (30a) is provided by the coil spring (35).
