Example Embodiment

[0047] Example one:

[0048] Such as Figure 1 to Figure 5 As shown, a groove 28 is provided on the end surface of the lower piece 14, and the groove 28 is equivalent to opening a blind hole in the lower piece 14. The shape of the groove 28 can be square or round, preferably a square. The end surface of the groove 28 is in contact with the sealing end surface of the lower flange 15. The lower flange 15 is provided with a lower flange passage 29 for communicating with the groove 28. The diameter of the lower flange passage 29 is d, and the lower flange passage 29 can It is set as a through hole to communicate with the second outlet of the gas switching device 27; but in order to facilitate the connection, the lower end of the lower flange passage 29 is not opened and becomes a blind hole. A lower method is provided on the side wall of the lower flange passage 29 The flange bypass hole 30, the lower flange bypass hole 30 communicates with the lower flange passage 29, and is used to...

Example Embodiment

[0057] Embodiment two:

[0058] Reference Figure 6 to Figure 10 As another embodiment, the difference from Embodiment 1 is that the groove 28 is provided on the lower flange 15 and is located on an end face of the lower flange 15 and the lower cylinder 13, preferably the center line of the groove 28 and The center line of the sliding piece 14 faces each other, the lower flange passage 29 is located in the middle of the groove 28 and communicates with the groove 28. One side of the lower flange passage 29 is provided with a lower flange bypass hole 30 for communicating with gas The second outlet of the switching device 27 is connected.

[0059] In order to ensure the seal, the distance between the inner wall of the groove 28 and the outer wall of the slide plate 14 is greater than or equal to 0.5-1.2 mm, and the diameter d of the lower flange channel 29 is less than or equal to the width A of the groove 28.

[0060] When the center line of the groove 28 coincides with the center li...

Abstract

The invention discloses a volume variable rotation compressor. The compressor comprises an outer shell, a motor and a cylinder component, the motor and the cylinder component are arranged in the outer shell; wherein the motor and the cylinder component are connected through a crank shaft, the tail part of a first slip sheet is provided with an elastic part; the tail part of a second slip sheet is not provided with an elastic part; a groove is arranged on the second slip sheet, a position where is opposite to the second slip sheet on a second flange, or a position where is opposite to the second slip sheet on a middle division plate; a tunnel which is used for communicating the groove is arranged on the cylinder component; the volume variable rotation compressor also comprises a gas switching device, which switches the pressure of the groove between a high-pressure side pressure and a low-pressure side pressure. Through controlling the pressure differential to control the movement of slip sheet, reliable switch between single cylinder operation and double-cylinder operation can be achieved, and thus leakage is effectively prevented; when the slip sheet stays still, the inner cylinder and the tail part of the slip sheet groove are both in a high-pressure state so as to avoid the phenomenon of gas mixing caused by pressure difference.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a variable capacity rotary compressor. Background technique [0002] Energy conservation and environmental protection are the development trend of the air-conditioning industry. Generally, air-conditioning systems use fixed-capacity compressors. When the room temperature reaches the set temperature during operation, the compressor will start and stop repeatedly. In this way, energy is consumed on the one hand, and room temperature changes on the other. Destroying the comfort, the compressor capacity control technology is a technology between frequency conversion and constant capacity, which can achieve the purpose of changing the compressor capacity and improving performance with the change of air conditioning load. It can be combined with the frequency conversion compressor to make up for the capacity of the frequency conversion compressor Insufficient adjustment, the existing variabl...
