FIELD: machine building.SUBSTANCE: pneumatic spring comprises thin-wall cylinder (1) to accommodate rod (2) with its seal (3) and piston (4) to make head end chamber (6) and rod end chamber (7). Said cylinder (1) has lengthwise cut-out (8) made over its entire length and is fitted coaxially in body (9). Piston (4) has through channel (10). Two air chambers (11, 12) are arranged between cylinder (9) body and thin-wall cylinder (1) walls to envelop said cylinder (1) in zones of said head end chamber (6) and rod end chamber (7). Air chamber (11) is connected via channels (13) with head end chamber (6). Air chamber (12) is connected via channels (14) with rod end chamber (7).EFFECT: ruled out puncture at impact loads.2 dwg
