Abstract
Пневматическая пружина, содержащая резервуар, размещенные в нем шток с поршнем, образующим в рабочей полости резервуара надпоршневую и подпоршневую полости, уплотнительный элемент штока, поршень имеет на боковой поверхности набор кольцевых канавок, в ряде канавок размещены уплотнительные кольца, отличающаяся тем, что поршень имеет две внутренние изолированные друг от друга кольцевые выемки, каждая из которых сообщается каналами хотя бы с одной своей кольцевой канавкой на боковой поверхности поршня, в каждой такой канавке расположено эластичное поршневое кольцо и экспандер в виде газообразной фазы, сквозной канал, соединяющий надпоршневую и подпоршневую полости пневматической пружины, причем одна внутренняя кольцевая выемка поршня сообщается с надпоршневой полостью, а другая внутренняя кольцевая выемка - с подпоршневой полостью посредством двух встречных обратных клапанов.A pneumatic spring containing a reservoir, a piston rod located in it, forming a piston and a piston cavity in the working cavity of the reservoir, a rod sealing element, the piston has a set of ring grooves on the side surface, sealing rings are located in a number of grooves, characterized in that the piston has two internal annular recesses isolated from each other, each of which is connected by channels with at least one of its annular grooves on the side surface of the piston, in each such groove is located an elastic piston ring and an expander in the form of a gaseous phase, a through channel connecting the piston and piston cavities of the pneumatic spring, with one internal annular recess of the piston communicating with the piston cavity and the other internal annular recess with the piston cavity through two counter check valves.
