FIELD: machine building.
SUBSTANCE: set of invention relates to machine building. Proposed assembly comprises flexible wall, first end element secured via flexible wall first end and piston assembly connected with said flexible wall along its second end. Piston assembly comprises outer shell composed by thin-wall material with metal properties, Outer shell comprises sidewall, end wall extending perpendicular to sidewall along its first end and having the first through bore. Sidewall makes second bore along outer shell second end. End plate is composed by thin-wall material with metal properties. Attachment column extends in lengthwise direction between said first and second ends. Outer shell, end plate and attachment column make the piston chamber inside piston assembly. Connectors from fluid material making a tight seal are arranged between end plate and outer shell and between attachment column and end plate. Proposed method comprises the steps that follow. First end element is connected via first end of flexible wall. Attachment column and end plate are secured to each other. End plate and outer shell are interconnected while piston assembly is jointed to flexible wall second end.
EFFECT: simplified design, reduced compressed gas losses.
