Abstract: A mechanical spreader along a spreading axis, characterized in that it comprises a support (1) and two spreading plates (2), each spreading plate (2) comprising at least one bevel (3), and in that it also comprises a central rod (4) able to slide in said support (1) between the two spreading plates (2), said central rod (4) comprising a plurality of bevels (5) having a profile complementary to the bevels (3) of said spreading plates (2), the bevels (5) of said central rod (4) being in contact with the bevels (3) of said spreading plates (2), said spreader also comprising return means able to exert a return force on the spreading plates (2), means for pushing the central rod (4) and means for immobilizing the spreading plates (2) in planes perpendicular to said spreading axis.

Abstract: A turbocharger includes a compressor and a compressor housing (1) surrounding the compressor, a turbine and a turbine housing (2) surrounding the turbine. The compressor housing (1) includes an inlet and an outlet for the air (4) entering a combustion chamber of an engine. The turbine housing (2) includes an inlet and an outlet for the exhaust gases (5), a shaft (3) linking the turbine and the compressor, at least one bearing for supporting and guiding the rotation of the shaft (3). The turbocharger includes attachment means (6, 7a, 7b) for attaching the turbine housing (2) to the compressor housing (1). The shaft (3) includes a free portion (8) between the two housings (1, 2), the attachment means (6, 7a, 7b) being suitable for allowing the passage of a flow of air circulating along the free portion (8) and around the turbine housing (2) and compressor housing (1).
