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： An electrically driven compressor has a closed vessel including upper and lower vessels, a compression mechanism disposed at the upper portion of the lower vessel to communicate, on its suction side, with the inside of the lower vessel and an electric motor disposed under the compression mechanism inside the lower vessel to electrically drive the compression mechanism. The compression mechanism includes a stationary impeller component having a stationary impeller, a rotary impeller component having a rotary impeller for engaging with the stationary impeller to define a plurality of spaces to be compressed between them, a crank shaft rotatably driving the rotary impeller component, a bearing component for supporting the crank shaft, a self-rotation restricting component for restricting the self-rotation of the rotary impeller component but allowing only its forced rotation, a thrust bearing for supporting the rotary impeller component axially biased to it, and a partition frame component interposed between the stationary impeller and bearing components. The partition frame component is interposed between the upper and lower vessels at their respective open ends so that both vessels may be completely sealed through the partition frame component by welding its entire outer periphery.

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.
摘要翻译：本发明提供一种用于空调装置等的制冷系统的低压涡旋压缩机。将润滑油以与电动机的旋转数成正比的方式间歇地供给到压缩机单元，避免润滑油供给过量或不足，并且即使在电动机的高速旋转中也能够适当地供给润滑油。因此，压缩机是高度可靠的。此外，在压缩机的吸入空间中设置有筛板，使得冷却剂或冷却介质中的润滑油能够有效地与冷却剂分离，从而提高润滑油的收集效率。此外，筛板可用于防止密封端被返回的冷却剂冷却。否则，密封端子会发生结露，会导致泄漏或短路，这是压缩机安全的重要障碍。

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： 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： 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： 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.
