摘要:
A scroll-type compressor has a stationary scroll frame 7 on which a discharge muffler 24 is provided so as to form a first discharge space 24a. First and second discharge passages 25, 26 are formed to extend through the stationary scroll frame 7 and a bearing 20 so as to provide communication between the first discharge space 24a and the interior of the hermetic container 1. The second communication hole opens in the interior of the hermetic container 1 through a guide member 29 at a level above the level of a lubricating oil in a lubricant reservoir 31. Since the opening of the second communication hole into the hermetic container is set by the guide member 29 at a level above the oil level in the lubricant reservoir 31, the discharge passage can be formed easily without requiring any special component which defines the passage.

A balance weight to equilibrate an inertial force due to reciprocation of an Oldham's ring is mounted so that a vibration due to an unbalanced inertial force of the Oldham's ring is transmitted in a direction perpendicular to or almost perpendicular to a connecting direction between the closed vessel and the accumulator, whereby a vibration resulting from an unbalanced inertial force of the compressor body due to the balance weight to equilibrate the inertial force on account of the reciprocation of the Oldham's ring is increased in a direction perpendicular to or almost perpendicular to the connecting direction between the closed vessel and the accumulator. The vibration, however, is reduced in the connecting direction or in a direction close to the connecting direction. As a result, vibrations of pipes connecting the closed vessel to the accumulator are reduced, and reduction of noise of the overall air conditioning system is attained.

In a sealed-type scroll compressor having a stationary scroll member and an orbiting scroll member, the stationary scroll member is fixed after rotating it in an orbiting direction of the orbiting scroll member by a predetermined angle from a phase angle position where a possible orbiting radius between both scroll members is made maximum at the temperature before driving the scroll compressor.

In a sealed electric scroll compressor, lubricating oil is collected in an oil collection pan mounted under a compression mechanism after the compression mechanism is lubricated thereby, the lubricating oil collected in the oil collection pan is discharged from a small hole at the side of the oil collection pan which is located remote from a delivery pipe for delivering a high-pressure refrigerant gas outward from a sealed container of the sealed electric compressor. The high-pressure refrigerant gas flows between the inner wall of the sealed container and a vertical cut part formed on the circumference of a stator of an electric motor.

In a scroll-type compressor, the revolving motion drive shaft 16, formed on the revolving end plate 12 at the side opposite to the revolving swirl blades 11, is fitted in an eccentric bearing eccentrically disposed inside of the main shaft of the crank shaft 6. The crank shaft 6 is connected to the rotor of the electric motor and is supported at the end portion thereof opposite to the main shaft by an upper bearing of a rolling type. Above the upper bearing, a rise preventing plate 24 for preventing the crank shaft 6 from excessively rising upwards is arranged in a fixed manner. The crank shaft 6 is so shaped as to have a stepped portion where the diameter of the shaft portion mounting the rotor 5 becomes stepwise greater than that of the shaft portion fitted in the upper bearing 21. Between the stepped portion and the inner race of the upper bearing 21 is provided an elastic member 26 which can be wave shaped. Between the rise preventing plate 24 and the end portion of the crank shaft 6 opposite to the main shaft of the crank shaft 6 a narrow clearance is maintained. By applying an elastic force of the elastic member 26 on the inner race of the upper bearing in the axial direction, abnormal noises from the bearing caused by axial vibrations and resonances of the shaft system can be prevented.

Impulsive sound of an Oldham ring is reduced and a driving noise of a scroll compressor is prevented from increasing. When a width of the key of the Oldham ring made of iron-based material is defined as t and a width of the orbiting-side key groove in the back surface of the surface plate of the orbiting scroll made of aluminum-based material and a width of the fixed-side key groove of the main bearing member made of aluminum-based material on the side of a thrust surface are defines as s, a gap d generated at s−t with respect to a key pitch L of the Oldham ring I set in a range of (6×10−5)≦d/L≦(3.5×10−4). With this, even if the key of the Oldham ring vibrates in the key groove, a collision force against the key groove is weakened, impulsive sound of the Oldham ring becomes small, and a driving noise of the scroll compressor is can be reduced.
