Problems solved by technology

[0006] However, for the above-mentioned scroll compressor, when the motor unit 60 stops driving, the refrigerant in the high-pressure side space (P1) flows into the compression space (S) through the discharge port 23 before the piston valve 41 closes the discharge port 23 Inside, pressure is applied in the reverse direction of the movable scroll 25 until the pressure reaches a balanced state, so the movable scroll 25 and the fixed scroll 21 collide with each other to generate noise

Embodiment Construction

[0024] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0025] like figure 2 , image 3 , Figure 4 As shown, the scroll compressor has the following structure: the inside of the box body 10 forms a closed container, and the suction pipe 13 and the exhaust pipe 11 are installed; the compression part 20 is located inside the box body 10 to inhale compressed refrigerant; the motor part 60 passes through The rotary shaft 61 provided along the vertical direction inside the casing 10 drives force to the compression unit 20 .

[0026] The compression unit 20 includes a fixed scroll 21 and a movable scroll 25 . The above-mentioned fixed scroll 21 is located inside the casing 10 and has a fixed scroll plate 12 with an involute shape; the movable scroll 25 has a movable scroll plate 27 with an involute shape corresponding to the fixed scroll plate 12, During the suction and compression process, multiple symmetri...

Abstract

An apparatus for preventing reverse rotation of movable vortex disk of vortex-type compressor has at least one pair of through holes symmetrically arranged at both sides of gas outlet for communicating the compressing space with high-pressure space. The piston cylinder in the static vortex disk has a bottom end communicated with said through hole and the piston has a channel for communicating said high-pressure space and compressing space. Its advantages are simple and compact structure, high effect and low noise caused by reverse rotation.

Description

technical field [0001] The invention relates to a device for preventing the reverse rotation of a movable scroll of a scroll compressor. In particular, it prevents the movable scroll from rotating in a vacuum state while preventing the movable scroll from reversing. Background technique [0002] The main structure of a general scroll compressor is as follows: figure 1 As shown, the scroll compressor is composed of a casing 10 and a compression part 20 and a motor part 60 inside the casing 10 . A sealed storage space is formed inside the box; the compressor 20 is disposed inside the box 10 to compress the refrigerant; the motor unit 60 provides driving force to the compression unit 20 . There is a suction pipe 13 on one side of the box body 10, and the suction pipe 13 can suck the medium from the outside. An exhaust pipe 11 is provided on the upper side of the suction pipe 13, and the exhaust pipe 11 discharges compressed refrigerant. [0003] The compression part 20 incl...
