DAMPING FORCE VARIABLE VALVE OF SHOCK ABSORBER
First Claim
1. A damping force variable valve configured to be coupled to a shock absorber, the damping force variable valve comprising:
- a retainer including a main body having an outer peripheral region including a diameter increasing in a direction away from the shock absorber;
a spool rod formed integrally with the main body to extend from a central region of the main body, the spool rod having a hollow portion formed at a central portion thereof,a spool inserted in the hollow portion of the spool rod;
a solenoid coupled to a lower side of the retainer; and
a spool pressurizing member installed in the solenoid and configured to move in response to electrical power applied to the solenoid to pressurize the spool.

Abstract
A damping force variable valve includes a retainer including a main body connected at a central region thereof to a high pressure region of a shock absorber cylinder, the main body having an outer diameter increased outwards, and a spool rod formed integrally with the main body to extend from the central region, the spool rod having a hollow portion formed at a central portion thereof to allow a spool to be inserted in the hollow portion, a solenoid coupled to a lower side of the retainer, and a spool pressurizing installed in the solenoid and configured to move in response to electrical power applied to the solenoid to pressurize the spool.

6. An apparatus, comprising:
-
a shock absorber having a cylinder, a reservoir chamber in fluid communication with the cylinder, a high-pressure region, a low-pressure region, the cylinder having a rebound chamber in fluid communication with the high-pressure region, and a reservoir chamber in fluid communication with the low-pressure region; a damping force variable valve main body coupled to the shock absorber and including a connecting port toward a central region of the main body and in fluid communication with the high-pressure region, the main body having a distal end and a proximal end with respect to the shock absorber, the distal end having a larger diameter than the proximal end; a spool rod having a hollow central region and formed from a unitary body of material with the main body toward the central region of the main body and spaced from the connecting port; a spool movably positioned in the hollow region of the spool rod; a solenoid coupled to the main body; and a spool pressurizing plunger positioned in the solenoid and in contact with the spool, the spool pressurizing plunger configured to move in response to electrical power applied to the solenoid to pressurize the spool.
