Embodiment 1

[0045] Embodiment one, such as figure 2 , 3 , 5a-5c, in some embodiments, the throttling mechanism 051 further includes a first elastic adjustment part 051c, the first elastic adjustment part 051c is located between the moving part 051a and the fixed part 051b, through The movement of the moving part 051a can squeeze the first elastic adjustment part 051c to change the size of the flow area of ​​the flow channel 12 between the moving part 051a and the fixed part 051b. Embodiment 1 of the present invention can squeeze the first elastic regulating part through the movement of the moving part through the cooperation form between the first elastic regulating part and the moving part and the fixed part, thereby effectively changing the area of ​​the circulation channel. Formed between the moving part and the fixed part, it realizes the effect of changing the oil intake according to the compressor rotation speed, thereby changing the oil pressure, and improving the energy efficien...

Embodiment 2

[0050] Embodiment two, such as Figure 6-7 , in some embodiments, the moving part 051a includes a first blocking part 0513 and a second blocking part 0514, an entry channel 16 is defined between the first blocking part 0513 and the second blocking part 0514, and the A helical second channel 17 is provided on the fixing part 051b, and the first blocking part 0513 and the second blocking part 0514 move integrally to adjust the communication position between the inlet channel 16 and the second channel 17, so as to Adjust the change of the channel length of the second channel 17 communicating with the inlet channel 16 , the second channel 17 forms a part of the helical section communicating with oil as the flow channel 12 . The moving part in the second embodiment of the present invention can form an entry channel between the first and second blocking parts by forming the structure, the entry channel can communicate with the second channel on the fixed part, and the entry channel ...

Embodiment 3

[0056] Embodiment three, such as Figure 8 , in some embodiments, the throttling mechanism 051 further includes a third elastic adjustment part 051e, the third elastic adjustment part 051e is filling fluid, and the filling fluid can be filled into the second channel 17, so One end of the filling fluid located in the second channel 17 is provided with a third blocking portion 051d, the third blocking portion 051d can block the filling fluid, and the third blocking portion 051d can block the filling fluid along the second channel 17. The spiral direction of the second channel 17 slides; one end of the second blocking part 0514 is in contact with the third blocking part 051d, and the filling fluid moves along the second channel 17 to drive the third blocking part 051d moves along the second channel to further drive the second blocking part 0514 to move helically. This is the preferred structural form of the third embodiment of the present invention, that is, the third elastic ad...

Abstract

The invention provides an oil way throttling device of a compressor, the compressor and an air conditioner, the oil way throttling device of the compressor comprises a main supporting seat, a first throttling channel and a throttling mechanism, the first throttling channel is arranged on the main supporting seat so that oil can flow, the throttling mechanism is arranged in the first throttling channel, and the throttling mechanism is arranged on the main supporting seat. The throttling mechanism can control the change of the throttling degree according to the rotating speed of a rotating shaft of the compressor, and then the pressure of the oil is controlled to change. The throttling capacity of the throttling mechanism is automatically adjusted through the rotating speed, the throttling capacity is weakened during high-frequency operation to avoid excessive back pressure, and the throttling capacity is enhanced during low-frequency operation to avoid energy efficiency reduction, so that the problem that the pressing force of the dynamic and static vortex plates is too large can be solved, and the problem that the movable vortex plates overturn can also be solved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to an oil passage throttling device of a compressor, a compressor and an air conditioner. Background technique [0002] The scroll compressor has the characteristics of simple structure, small size, light weight, low noise, high mechanical efficiency and stable operation. A fixed scroll and a movable scroll are installed in a high back pressure scroll compressor. The movable scroll compresses the fluid by rotating while engaging with the fixed scroll, and the fluid is compressed to act on the scroll. The force on the disk that tends to tip the orbiting scroll, causing leakage and reducing compression efficiency. In order to counteract the influence of this force, a back pressure is usually introduced on the back of the movable scroll, so that the movable scroll is pressed tightly against the static scroll. Large friction loss reduces the compression efficiency, so usually a pa...
