Abstract

Пневматическая пружина, содержащая тонкостенный цилиндр, размещенные в нем шток с поршнем, образующим в рабочей полости цилиндра надпоршневую и подпоршневую полости, уплотнительный элемент штока, отличающаяся тем, что тонкостенный цилиндр имеет, по крайней мере, одну продольную прорезь по всей своей длине и помещен коаксиально в цилиндрическом корпусе, поршень имеет сквозной канал, соединяющий надпоршневую и подпоршневую полости, между стенками цилиндрического корпуса и тонкостенного цилиндра размещены две пневмокамеры, охватывающие снаружи тонкостенный цилиндр соответственно в областях надпоршневой и подпоршневой полости, причем пневмокамера в области надпоршневой полости соединена с надпоршневой полостью каналами, а пневмокамера в области подпоршневой полости соединена каналами с подпоршневой полостью.A pneumatic spring containing a thin-walled cylinder, a rod placed in it with a piston forming a supra-piston and sub-piston cavity in the working cavity of the cylinder, a rod sealing element, characterized in that the thin-walled cylinder has at least one longitudinal slot along its entire length and is placed coaxially in the cylindrical body, the piston has a through channel connecting the supra-piston and sub-piston cavities, two pneumatic chambers are placed between the walls of the cylindrical body and a thin-walled cylinder, covering on the outside, a thin-walled cylinder, respectively, in the areas of the supra-piston and sub-piston cavity, and the pneumatic chamber in the area of the supra-piston cavity is connected by channels, and the pneumatic chamber in the area of the sub-piston cavity is connected by channels with the sub-piston cavity.

Claims
