Abstract

The invention relates to an adjustable damper. The adjustable damper mainly comprises a shell, a piston bolt, a piston plate, a piston sealing ring, a piston, a connecting bolt, a T-shaped installingbase, a through cover outer sealing ring, a through cover, a through cover inner sealing ring, a through cover bolt and the like. The head of the piston is provided with a kidney-shaped hole for installation and a circulation gate hole set of damping media, the total cross sectional area of the circulation gate hole set is determined in cooperation with a baffle, and therefore adjustment of damping coefficients is achieved. The damper can be installed on many structure and equipment through an installing hole of the T-shaped installing base and an installing hole of the shell. The adjustable damper is simple in structure, reliable in work and high in economic benefit, and adjustment of the damping coefficients can be achieved according to the actual needs.

Description

technical field [0001] The invention belongs to the technical field of dampers and relates to an adjustable damper, in particular to an adjustable damper which realizes the adjustment of the damping coefficient by adjusting the relative positions of parts on the piston assembly. Background technique [0002] Chinese patent taper hole stepless adjustable valve (CN201010583559) and a simple adjustable decompression valve (CN201010125624) are based on the combination of a cone rod and a cylindrical hole. The gap is controlled by axial movement, and multiple sets of cone rods and cylinders are set. Hole fit to achieve flow and flow direction control. Practice has found that it is not perfect in terms of stability. Contents of the invention [0003] In order to overcome the above-mentioned shortcoming of the prior art, the object of the present invention is to provide an adjustable damper, through the adjustment of the relative position of the grid and the hole, the size of th...
