ABSTRACT:
The machine includes a fixed disk (2) comprising a spiral wall (3), a mobile disk (4) also comprising a spiral wall (5) cooperating with that of the fixed disk, and means (11, 16, 22, 23) for driving circular translation movement of the mobile disk, the mobile disk being positioned axially by a system including a shoe (25, 32, 36) rubbing between two lateral abutments (26, 27-34, 35-39, 40), one member of the pair of members (i.e. the shoe or the lateral abutments, being attached to a fixed frame (1) and the other member of this pair of members being fastened to the mobile disk (4), characterized in that the fixed disk (2) is joined on the side opposite the mobile disk (4) to a fixed central shaft (7) joined to the frame (1) and including a discharge passage (8), the central shaft (7) being surrounded by a sealing bellows (12) connected at one end to the frame and at its other end to a connecting flange (10, 10A) the periphery of which, around the fixed disk (2), is joined to the mobile disk (4) beyond its spiral wall (5), the mobile disk (4) and the flange (10, 10A) forming a casing enclosing the fixed disk (2), the space (13) between the bellows (12) and the central shaft (7) constituting a suction passage, and in that the mobile disk axial positioning system is external of the internal volume of the casing (4-10, 10A), the member attached to the mobile disk, i.e. the shoe or the lateral abutments, being attached to the casing and projecting externally of it.
