Abstract (en)

[origin: WO9619667A1] A compressor comprising a rear side member (20) that includes a rear head (6) fixed to one end of a cam ring (1), and a movable plate (4) held by the rear head (6) to face one end of a rotor (2) and capable of moving along the axis of a driving shaft (7). When the compressor is started, the movable plate (4) is temporarily pushed to leave the rotor by the pressure of a compression chamber partitioned by vanes (14). As a result, a gap is defined between the movable plate (4) and the rotor (2), and it allows liquid to escape so that liquid compression can be avoided. As the start of the compressor (that is, when a solenoid clutch is turned on), the driving shaft (7) moves towards the rear side and the rotor (2) is pressed against the movable plate (4). However, because the movable plate (4) temporarily moves towards the side opposite to the rotor, the pressure of sliding contact between the rotor (2) and the movable plate (4) lowers, and seizure can be restricted.
