A variable geometry compressor housing module has a housing (1) into which a diffuser plate (3), a unison ring (5) and vanes (7) supported by a backplate (9) are inserted. The backplate is fixed to the housing by a crimping process. An actuation mechanism (13) for actuating the vanes (7) is provided on an inlet side of the housing (1). Furthermore, a shroud groove is partly defined by the diffuser plate (3).
