SHOCK ABSORBER

摘要

A shock absorber includes a reservoir between a cylinder and an outer tube, in which hydraulic liquid and gas are sealed; a middle tube between the cylinder and the outer tube; a connecting pipe in the lateral wall of the middle tube, which includes a tip end extending toward the outside of the outer tube; an opening in the outer tube, allowing hydraulic liquid to flow from the outside of the outer tube into the reservoir through the outer side of the connecting pipe; and a partition member in the reservoir, which includes a partition wall that configured to regulate hydraulic liquid's upward flow from the opening in the reservoir. The partition member is made of flexible resin or rubber, provided with a fitting hole, and fitted to the connecting pipe with interference with the connecting pipe inserted through the hole.

主权项

1. A shock absorber for being installed between two relatively displaceable members, the shock absorber comprising:
a cylinder in which a hydraulic fluid is sealed; a piston inserted in the cylinder; a piston rod interconnected to the piston and extending out of the cylinder; an outer tube mounted over an outer circumferential surface of the cylinder; a reservoir formed between the cylinder and the outer tube and in which the hydraulic liquid and gas are sealed; a middle tube mounted between the cylinder and the outer tube; a connecting pipe disposed in a lateral wall of the middle tube and including a tip end extending toward the outside of the outer tube; an opening formed in the cuter tube and allowing the hydraulic liquid to flow from the outside of the outer tube into the reservoir through the outer side of the connecting pipe; and a partition member placed within the reservoir, the partition member including a partition wall that, in a state that the shock absorber is located between the two relatively displaceable members, regulates an upward flow of the hydraulic liquid from, the opening to an upper portion of the reservoir, wherein the partition member is made of flexible resin or rubber, and the partition member is provided with a fitting hole, and fitted to the connecting pipe with interference with the connecting pipe inserted through the fitting hole.
