Abstract (en)

[origin: EP0882892A1] The scroll machine comprises a fixed disc (5) with a spiral working face (6) and a mobile disc (7) with a spiral working face (8) and a drive to rotate it. It has a sealing bellows (15) connected at one end to a component (14) which rotates with the mobile disc and at the other to a fixed part of the machine, and designed to separate the fluid circuit from the mechanical drive components. The fixed disc is connected on its side opposite the mobile disc to a central fixed shaft (10) with a feed channel (11). The shaft is surrounded by the bellows, with the space between it and the shaft forming a suction duct, while a main hollow rotary shaft (19) surrounds the bellows and is supported by one or more bearings (23, 24). One end of the main shaft has an eccentric circular bore which co-operates with a drive member linked to the mobile disc, and the drive incorporates an electric motor rotor (25) which is connected to the outside of the main shaft (19), and a fixed stator (26) surrounding the rotor.
