Problems solved by technology

[0005] However, in compressors with high and low pressure chambers, since the moving mechanism is located in the large space of the low pressure chamber, its oil supply and lubrication become difficult. At the same time, in the small space of the high pressure chamber, the separation of the discharged gas and oil also becomes necessary. The problem to be solved, besides, it is difficult to ensure the oil supply and lubrication of the sliding vane back pressur

[0027] First embodiment

[0028] See 1- figure 2 , The rotary compressor includes a compression assembly and a motor assembly arranged in a shell. The compression assembly is located at the lower part of the shell, and the motor assembly is located at the upper part of the shell. The compression assembly includes a cylinder 12, a piston and a sliding block arranged in the cylinder 12 The piece 14, the long bearing 11 and the short bearing 13 for supporting the eccentric crankshaft 15 are arranged on the cylinder 12. The internal space of the housing is divided by the short bearing 13 into a low pressure chamber 1 located at the upper part and a high pressure chamber 2 located at the lower part, short bearing An upper oil pool 4 is provided on 13.

[0029] In the low-pressure chamber 1, the oil brought in by suction is separated and accumulated in the upper oil pool 4 of the short bearing 13. The lower end of the short bearing 13, that is, the end of the boss of the short bearing ...

Example

[0035] Second embodiment

[0036] See image 3 In this embodiment, the oil guide cover 18 is eliminated, and a blind hole is provided at the lower end of the short bearing 13, and the blind hole and the eccentric bearing jointly enclose an oil storage cavity.

[0037] See the first embodiment for the remaining unmentioned parts, and will not be repeated.

Example

[0038] The third embodiment

[0039] See Figure 4 In this embodiment, the lower oil sump 5 located in the lower shell 24 is arranged on the bottom side of the shell, and the groove is a single groove instead of the annular groove as in the first embodiment.

[0040] The inner muffler 20 is provided with more than one inner spouting outlet on the side, and the inner spout is composed of an inner muffler filter 20a; the outer muffler 21 is provided with more than one outer spouting outlet on the side, the outer spout The outlet is provided with an outer muffler filter screen 21a, the inner muffler filter screen 20a and the outer muffler filter screen 21a are arranged in opposite directions; the outer muffler filter screen 21a is backed to the lower oil sump 5. The outer discharge port on the outer muffler 21 is arranged in a direction 180 degrees apart from the groove on the lower oil pool 5.

[0041] See the first embodiment for the remaining unmentioned parts, and will not be repea...

Abstract

The invention provides a rotary compressor, comprising a compression component and a motor component which are arranged in a shell, wherein the compression component is arranged at the lower part of the shell; the motor component is arranged at the upper part of the shell; the compression component comprises an air cylinder, a piston arranged in the air cylinder and a slip sheet; a long bearing and a short bearing which are used for supporting an eccentric crankshaft are arranged on the air cylinder; the short bearing is used for dividing the inner space of shell into a low-pressure cavity atthe upper part and a high-pressure cavity at the lower part; the short bearing is provided with an upper oil pool, and an oil storage cavity is arranged at the lower end of the short bearing; the oilstorage cavity is communicated with the lubricant channel of the eccentric crankshaft; one end of an oil conduit is communicated with the upper oil pool and the other end of the oil conduit is communicated with the oil storage cavity; an oil conducting cover is arranged at the lower end of the short bearing; and the oil conducting cover, the lower end of the short bearing and the eccentric crankshaft form an oil storage chamber. The rotary compressor is simple and reasonable in structure, flexible in operation, good in lubrication performance, good in oil-gas separation effect, low in oil seal amount and high in safety degree.

Description

technical field [0001] The present invention relates to a rotary compressor. Background technique [0002] R22 refrigerant has been listed as a phase-out refrigerant by the "Montreal Protocol". Europe and Japan have already begun to switch to R410A refrigerant replacement, and the United States will also ban the use of R22 in new refrigeration products in 2010. China has also accelerated the pace of R22 phase-out, which will be frozen at the average level from 2009 to 2010 in 2013, and the requirement of 10% of the baseline level must be reduced in 2015. And some major domestic brands have also begun to launch environmentally friendly air conditioners with R410A as the refrigerant. However, the GWP value of R410A is larger than that of R22, and the "Kyoto Protocol" has listed R410A as a greenhouse gas for controlled emissions. Therefore, R410A is by no means a long-term alternative. [0003] As an alternative refrigerant to HCFC, such as R22, HFC, such as R410A and R407C,...
