Abstract

Naprężacz zawiera mieszek (1) w kształcie walca, złożony z pokryw (4), połączonych z falistą powłoką (2) i zewnętrznymi połączeniami krańcowymi (7). W mieszku (1) znajduje się gaz o ciśnieniu niższym od ciśnienia na zewnątrz, przy czym wewnątrz mieszka (1), między pokrywami (4), jest umieszczony co najmniej jeden pierścień wzmacniający (3), zamocowany do powłoki (2) w płaszczyźnie normalnej do osi mieszka (1).The tensioner comprises a bellows (1) in the form of a cylinder, consisting of covers (4) connected to a corrugated shell (2) and external end joints (7). The bellows (1) contains gas at a pressure lower than the pressure outside, where inside the bellows (1), between the covers (4), there is at least one reinforcing ring (3), attached to the coating (2) in the normal plane to the axis of the bellows (1).
