Beschreibung
Zusammenfassung:	Provided is a frequency-sensitive shock absorber, which includes a cylinder filled with a working fluid and a piston rod having one end disposed inside the cylinder and the other end extending to the outside of the cylinder. The frequency-sensitive shock absorber includes a main piston valve assembly and an auxiliary piston valve assembly. The auxiliary piston valve assembly includes: a spool unit configured to open or close a communication passage for communicating a rebound chamber with a compression chamber while moving within a housing; and upper and lower support members configured to support the spool unit. The upper and lower support members have protrusions protruding toward the spool unit, respectively, and as the spool unit moves, the communication passage is closed when the protrusions of the upper and lower support members contact the spool unit.
