Abstract: The arrangement and the process are applied in a compressor comprising: a cylinder block (2); a movable assembly including a piston (5); and a resonant spring (11) having a first end portion (11a), affixed to the cylinder block (2) by a first fixation assembly (20), and a second end portion (11b) affixed to the movable assembly by a second fixation assembly (30). The first or the second fixation assembly (20, 30) comprises a bearing portion (21, 31) attached around one of the end portions (11a, 11b) of the resonant spring (11) and having a fixation face (21b, 31b), and a bearing receiving portion (22, 32), previously attached to the cylinder block (2) or to the movable assembly and having a junction face (22b, 32b), the fixation and junction faces (21b, 31b, 22b, 32b) being welded together, securing the resonant spring (11) to the movable assembly and to the cylinder block (2), maintaining the movable assembly concentric to the cylinder (2a) and in a predetermined axial positioning.
