A recess is provided in the wrap of a stationary scroll in the vicinity of a terminal end thereof on the side of a suction chamber, so that an orbital scroll can be prevented from collision against the stationary scroll, thereby avoiding breakage of both scroll wraps and occurrence of noises. Further, with the provision of another recess in the orbital scroll wrap in the vicinity of a terminal end thereof, the orbital scroll can be prevented from colliding against the stationary scroll, thereby preventing breakage of both scroll wraps and occurrence of noises.

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.

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 disposesd 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.
