Example Embodiment

[0053] Example two

[0054] See Figure 3a to Figure 3c The technical solution of the second embodiment is different from the technical solution of the first embodiment described above in the following: In this embodiment, the sub-channel 108 is only provided on the circumferential edge of the fixed scroll 3.

[0055] See Figure 3a to Figure 3c , The sub-channel 108 includes a first throttle groove 301 provided on the circumferential edge of the fixed scroll 3. The first throttle groove 301 is provided inside the stationary scroll 3 and the arc of the first throttle groove 301 is consistent with the arc of the stationary scroll 3. The circumferential edge of the fixed scroll 3 is a first boss 303, and the first throttle groove 301 is provided inside the first boss 303. The passage 100 further includes a first introduction hole 302 provided in the fixed scroll 3 and a second introduction hole 102 provided in the bracket 1. The fluid flows to the back pressure chamber 9 through th...

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...
