摘要： 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.

摘要： An outlet check valve includes an output valve seat provided at an outlet port or an outlet passage for compressed air in the vicinity of an outlet port of a compression mechanism and an outlet valve body. The valve seat and valve body are biased away from each other by a gravitational force or a spring. With this arrangement, even if a compressor is rotated at a low speed during a start-up operation, it is possible to cause stagnant liquid to undergo reverse flow into an accumulator disposed on the suction side and to store the liquid temporarily, thereby removing the liquid in the compression spaces and the suction passages and facilitating the start-up operation in a normal rotational direction. A pressure difference between the pressures upstream and downstream relative to the valve body is large when the normal rotating operation is stopped. By this pressure difference, the outlet valve body is moved to close the outlet valve seat, thereby to prevent the reverse rotation of the compression mechanism.

摘要： A swirling spiral impeller portion 13 is structured such that a pressure between the suction and discharge pressures acts on a part of the rear surface thereof. The compressor includes a means for adjusting and cooling the intermediate pressure which acts on a part of the swirling spiral impeller portion 13 by means of the lubricant oil stored in a lubricant oil reservoir 26 to which the discharge pressure in the sealed container acts. The lubricant oil supplied to the compression portion is provided under any pressure condition, and is always supplied stably. As the lubricant oil is cooled, it does not reduce the efficiency greatly.

摘要： A compressor includes a communication hole 42 through which lubrication oil in an oil reservoir 5 is supplied to a back pressure chamber 39 at least through an eccentrically driving bearing 15, and a communication bore 45 or gap through which the lubrication oil in the back pressure chamber 39 is fed into compression spaces, and a constricted resistance member 44 for regulating the oil flow rate is provided on the communication hole 42. The passage resistance can be made larger in comparison with the case where resistance is caused in a small space of a sliding portion of a bearing, and an accurate value of the passage resistance can be preset with the oil flow rate being low, thereby preventing flow of the lubrication oil to the compression operating spaces from increasing in quantity. Thus, there is provided a highly reliable scroll compressor which has a high compression efficiency, consumes power constantly, and has no risk of compression of the lubrication oil in the compression operating spaces.

摘要： 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.

摘要： The scroll gas compressor of the invention is so constructed that an enclosed container is partitioned by a fixed scroll member into a high pressure chamber and a low pressure chamber for gas-liquid separating intake refrigerant and storing it, the low pressure chamber being disposed at the lower portion and the high pressure chamber at the upper portion of enclosed container, the high pressure chamber disposing therein a drive unit related to a scroll compression mechanism and a lubricating oil sump, and the fixed scroll member serving also as part of the bottom of the lubricating oil sump, thereby providing that is small-sized, wide in an operational speed range, and superior in durability, and that prevents absorption of heat and noise propagation from the low pressure chamber serving as both the gas-liquid separation chamber and the reservoir of fluid, thereby improving the compression efficiency and lowering noise.

摘要： Bearing lubrication in a scroll compressor can be reliably effected at a sufficient flow rate independently of the flow rate of the lubricating oil supplied to the compression chambers 14 through the provision of a rotary-type displacement oil pump having a pump ring 25 which is adapted to orbit by the movement of the orbiting drive shaft 16. In addition, a lubricating oil sump and an oil intake passage communicating therewith are provided in close vicinity to the compression mechanism 2, thereby making it possible to operate the compressor without involving any backward flow of refrigerant gas in the oil feeding passage over a wide range of operating speed.

摘要： The present invention provides a low-pressure scroll compressor for use in a refrigerating system of an air conditioning apparatus or the like. Lubricating oil is intermittently supplied to a compressor unit in proportional relation to the rotating number of the motor, avoiding an excessive or insufficient supply of a lubricating oil and realizing a proper supply of the lubricating oil even in high-speed rotation of the motor. Thus the compressor is highly reliable. Further, a screening plate is provided in the suction space of a compressor, so that the lubricating oil in the coolant or cooling medium can be effectively separated from the coolant, resulting in enhancement of collecting efficiency of the lubricating oil. Moreover, the screening plate is useful to prevent a hermetic terminal from being cooled by the returning coolant. Otherwise, dew condensation would occur on the hermetic terminal, and leakage or shortcircuiting would be caused, a vital obstacle to the safety of the compressor.

摘要： A scroll compressor has a closed vessel in which a compression mechanism having orbiting and stationary scroll elements in engagement with each other is accommodated. A crankshaft is coupled with the orbiting scroll element and rotatably supported by a crank bearing. The crankshaft is rotated by an electric motor having a stator and a rotor so that the orbiting scroll element may orbit relative to the stationary scroll element. A plurality of balance weights are provided for maintaining static and dynamic balances of rotary elements including the orbiting scroll element, the crankshaft, and the rotor. The static and dynamic balances are calculated using at least a clearance between the crankshaft and the crank bearing.
