Embodiment 2

[0054] see Figure 3a to Figure 3c The technical solution of the second embodiment has the following differences from the technical solution of the first embodiment above: In this embodiment, the sub-channel 108 is only provided on the peripheral edge of the fixed scroll 3 .

[0055] see Figure 3a to Figure 3c , the subchannel 108 includes a first throttling groove 301 disposed on the peripheral edge of the fixed scroll 3 . The first throttling groove 301 is arranged inside the fixed scroll 3 and the radian of the first throttling groove 301 is consistent with the radian of the fixed scroll 3 . The peripheral edge of the fixed scroll 3 is a first boss 303 , and the first throttling groove 301 is arranged inside the first boss 303 . The channel 100 also includes a first introduction hole 302 provided on the fixed scroll 3 and a second introduction hole 102 provided on the bracket 1 . Wherein, the fluid flows to the back pressure chamber 9 through the exhaust chamber 6 , the...

Embodiment 3

[0058] see Figure 4a to Figure 4c , the technical solution of the third embodiment has the following differences from the technical solution of the first embodiment above: In this embodiment, the sub-channel 108 is only provided on the peripheral edge of the bracket 1 . Figure 4c The middle arrows indicate the introduction of back pressure fluid flow paths.

[0059] Such as Figure 4a to Figure 4c As shown, the sub-channel 108 includes a second throttling groove 101 disposed on the peripheral edge of the bracket 1 , the second throttling groove 101 is disposed inside the bracket 1 and the arc of the second throttling groove 101 is consistent with the arc of the bracket 1 . The peripheral edge of the bracket 1 is a second boss 103 , and the second throttling groove 101 is arranged inside the second boss 103 . The channel 100 also includes a first introduction hole 302 provided on the fixed scroll 3 and a second introduction hole 102 provided on the bracket 1 . Wherein, the...

Abstract

The invention discloses a scroll compressor, and relates to the field of compressors. The machining difficulty of the scroll compressor is reduced. The scroll compressor comprises an air exhaust cavity and a backpressure cavity; a channel for communicating the backpressure cavity with the air exhaust cavity is formed between the backpressure cavity and the air exhaust cavity, and the channel is constructed to enable the flowing direction of fluid flowing into the channel to be changed by at least one time in the channel; by the adoption of the technical scheme, the channel for communicating the backpressure cavity with the air exhaust cavity is formed between the backpressure cavity and the air exhaust cavity, the positions for machining the channel are many, space is large, and the machining difficulty of the scroll compressor can be reduced; after the fluid flows into the channel, on one hand, the fluid collides with the inner wall of the channel, energy is consumed, and therefore the fluid flowing speed is reduced, and the magnitude of the pressure of the fluid introduced into the backpressure cavity is reduced; and on the other hand, the channel of the structure can be made to be longer, and therefore the throttling effect is ensured.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a scroll compressor. Background technique [0002] In a scroll compressor, the movable scroll and the fixed scroll mesh to form several compression chambers. The pressure of each compression chamber rises during the compression process, thereby generating a gas force that separates the movable scroll from the fixed scroll. In the prior art (such as the patent documents of application publication numbers CN102308093A and US6872063), in order to suppress the separation between the movable scroll and the fixed scroll, a part of the high-pressure gas (including lubricating oil) in the compression chamber is usually throttled and depressurized. The back of the movable scroll is introduced to form a back pressure, and the movable scroll and the static scroll are pressed together. Since excessive back pressure will increase the friction and wear between the orbiting scroll and the fixed scr...
