Abstract
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.
