Lower cover assembly for a compressor with variable capacity

Abstract

The utility model relates to scroll compressor technical field especially, and it is a compressor variable volume's lower cover subassembly, the utility model discloses lower cover and support leg, support leg is divided into according to the different function: only bear the support compressor function support leg and bear the compressor function and bear the lower cover storage refrigeration oil function oil storage support leg, lower cover is divided into the bottom closed oil storage lower cover with support leg cooperation and the bucket type lower cover with oil storage support leg cooperation according to the different support leg structure, the utility model discloses technical scheme solves the prior art in order to increase the compressor refrigeration oil filling quantity, adopts the mode for increasing the overall height of compressor, can lead to the overall height of compressor too high, the gravity moves up, produces the sway in the operation process, leads to bolt loosening, equipment displacement, appears stress fatigue, increases the leakage and the fracture risk, adopts the mode for increasing the diameter of lower cover and shell, can lead to compressor overall weight increase floor space increase, causes the waste to cost and system space etc. problem.
