FIELD: transportation.
SUBSTANCE: device comprises pneumatic spring including cylinder with stem installed in it. Volume between stem and cylinder is filled with gas under pressure. With its one end pneumatic spring is fixed in aviation engine, and with its other end - in nacelle jacket fold, at that stem is arranged as hollow and is installed in cylinder so that volumes of internal cavity of hollow stem and cylinder create single volume. In open end of hollow stem, along axis, nozzle is installed, having hole diametre at the end that is considerably lower than diametre of hollow stem cavity, at that nozzle protrudes over end of hollow stem by value sufficient for preservation of filled oil level above sealing rings.
EFFECT: increased reliability, improved operation conditions and reduced weight of structure.
