CONTINUOUS DAMPING CONTROL SHOCK ABSORBER OF DUAL SOLENOID VALVE STRUCTURE

摘要

Provided is a continuous damping control shock absorber of a dual solenoid valve structure. The continuous damping control shock absorber of the dual solenoid valve structure includes a rebound solenoid valve and a compression solenoid valve. In the continuous damping control shock absorber, a separator tube for interworking prevention is installed to form a connection chamber at a position where the rebound separator tube and the compression separator tube are connected, thereby preventing interworking of the rebound solenoid valve and the compression solenoid valve 40. A communication hole is formed in the compression separator tube to communicate with the connection chamber. The separator tube for interworking prevention is configured such that the fluid discharged from the rebound solenoid valve flows into not the low-pressure reservoir chamber but the high-pressure compression chamber during the compression stroke, thereby improving the operational independence of the rebound solenoid valve and the compression solenoid valve. Therefore, it is possible to solve the problem that the compression damping force and the rebound damping force are interworked by the opening of the passage of the rebound solenoid valve during the compression stroke, and to effectively prevent a reduction in the compression damping force.
