摘要： A multistage compressor (10) is driven by a rotary electric motor (20). The rotor (25) is fixed to the lower end of the rotating shaft (23) by a bolt (34) screwed into the shaft (23). To secure the rotor (24) against rotary movement relative to the shaft, a detent key (35) is provided in a groove of the rotor. The rotor is secured against axial displacement by a stepped flywheel (40) for suppressing torque fluctuations and providing stable operation of the compressor. The flywheel may be locked against rotary displacement by the same detent key (35,45A) which is used for the rotor or alternatively by shrink-fitting. The cylinder (71) space is sealed against leakage by O-ring seals arranged in chamfers (90) on the outer circumference of the cylinder liner (71).

摘要： A compression system comprises a multicylinder rotary compressor in which a sealed container (12) stores a driving element (14) and first and second rotary compression elements (32,34) driven by a rotation shaft of the driving element. The first and second rotary compression elements comprise first and second cylinders (38,40), first and second rollers (46,48) which are fitted into eccentric portions formed in the rotation shaft and which eccentrically rotate in the respective cylinders, and first and second vanes (50,52) which abut on the first and second rollers to partition the inside of each cylinder into low and high-pressure chamber sides. The first vane (50) is urged toward the first roller (46) by a spring member (74). The multicylinder rotary compressor is started in a state in which suction-side pressures of both the rotary compression elements (32,34) are applied as a back pressure of the second vane (52) and after starting the discharge-side pressures of both the rotary compression elements (32,34) are applied as the back pressure of the second vane (52), thereafter the back pressure of the second vane (52) is set to be an intermediate pressure between the suction-side and discharge-side pressures of both the rotary compression elements (32,34).
