1. A frequency sensitive type shock absorber, which includes a cylinder and a piston valve partitioning the cylinder into a rebound chamber and a compression chamber, the frequency sensitive type shock absorber comprising:
an inner passage which connects a through-hole formed in a side of the piston rod to an opening formed in a lower portion thereof; a housing which is connected to a lower portion of the piston rod and in which a chamber part is formed, the housing including a bypass hole formed such that an upper portion of the chamber part is opened to connect to the opening, and a lower portion of the chamber part communicates with the compression chamber; a spool which is formed within the chamber part and is elevated by a fluid flowing into the chamber part; a pair of partition members that extends from a side of the chamber part to an outer periphery of the spool to partition the chamber part into an upper chamber and a lower chamber, and provides a restoring force to the spool; a guide member which is formed between the pair of the partition members, has a elastic force, and guides the pair of the partition members to maintain a position thereof; and a pair of elastic members which are formed in the upper chamber and the lower chamber to prevent a fluid from penetrating between the pair of the partition members and the side of the chamber part, and assist a restoration of the partition members by elasticity. |
