Abstract (en)

[origin: WO2022152722A1] The cylinder (1) comprises a cylindrical shell (3) defining an axis (A-A) of the cylinder with two opposite end walls (5) associated with the axial ends of the cylindrical shell (3). The cylindrical shell (3) and the end walls define a pressurizable hollow inner space (7). At least one of, and preferably both, the two axial ends (3A) of the cylindrical shell (3) comprises an annular inner projection (11), which extends radially towards the axis (A-A) of the cylinder (1) and has a minimum inner diameter (D1) smaller than a maximum diameter (D2) of the respective end wall (5), and the respective end wall (5) is so mounted that a portion (5B) of the end wall (5) having the maximum diameter (D2) is arranged in an axially innermost position with respect to a portion of the annular inner projection (11) having the minimum inner diameter (D1).
