Abstract
An apparatus for shock absorbing may include a structure in which the working chamber may extend to the lower end of the block in which the valve or the like is disposed. The shock-absorbing apparatus may increase the stroke range of the piston performing the compression stroke and the tension stroke.
Claims20
An apparatus for shock absorbing comprising:
- a block configured to have a through-hole penetrating vertically, and a first flow path and a second flow path;
- a first tube configured to extend vertically while passing through the through-hole, and have a penetrating portion passing through both inner and outer circumferential surfaces at a portion extending below the block;
- a piston assembly configured to perform a compression stroke or a tension stroke, and have a piston valve disposed within the first tube, the piston valve dividing the first tube into a tension chamber at an upper side and a compression chamber at a lower side, and a piston rod coupled with the piston valve;
- a second tube disposed to surround a portion of the first tube extending below the block, the second tube forming a first intermediate chamber communicating the compression chamber with the first flow path between the second tube and the first tube;
- a third tube disposed to surround a portion of the first tube extending above the block, the third tube forming a second intermediate chamber communicating the tension chamber with the second flow path between the third tube and the first tube;
- and
- a reservoir in communication with the first flow path and the second flow path.
