Abstract: The device comprises a nut (4) floatingly housed in a seat made in a barrel (3) of partially cylindrical form and provided with a radial through-hole (10) emerging in the seat and permitting the passage, with play, of the threaded rod of a screw (6) intended to interact with the said nut for the assembly of two parts (1, 2). The bearing surfaces opposite the seat and the nut (4) are provided so as to form a pivot joint for taking up any angular offset between the axis (13) of the screw (6) and the axis (14) of the through-hole (10) of the barrel. On its periphery, the nut (4) is provided with means (23) for immobilization in rotation relative to its seat in the barrel (3). The device also comprises means (5) for retaining the nut (4) on the barrel as well as a pair of washers (7, 8) for compensating for a variation in thickness.

Abstract: In this compressor stator having a housing in one piece a circumferential groove having a radially inner part of reduced width is formed for each stage in the wall of the cavity of the housing and communicates with the exterior of the housing by way of at least one radial opening having sufficient size to provide a passage for a vane base. The vane bases are disposed in a contiguous fashion in the groove and are radially supported by said inner part of the latter. A chain surrounds all the bases and bears radially against each one thereof.
