Embodiment Construction

[0032] The following description of preferred embodiments is exemplary only and in no way restricts the invention and its application or usage. The same reference numerals are used to denote the same components in the respective drawings, and thus the configurations of the same components will not be described repeatedly.

[0033] The present applicant has noticed the above-mentioned problems, and solved the above-mentioned problems by designing the following compressor.

[0034] The following will refer to figure 1 The structure of a double-scroll scroll compressor 1 according to an embodiment of the present invention is described. Such as figure 1 As shown, compressor 1 includes a generally closed housing 10 . The housing 10 may be composed of a substantially cylindrical main body 10a, a top cover 10b provided at one end of the main body 10a, and a bottom cover 10c provided at the other end of the main body 10a. A partition 12 is provided between the top cover 10b and th...

Abstract

The invention discloses a scroll compressor. The scroll compressor comprises a fixed scroll part and a movable scroll part which are engaged; and a first air suction opening, a second air suction opening, a first exhaust opening and a second exhaust opening are limited by the fixed scroll part, a first compression path is formed between the first air suction opening and the first exhaust opening,a second compression path is formed between the second air suction opening and the second exhaust opening, the compressor further comprises a bypass channel enabling at least one of the first compression path and the second compression path to be bypassed to the air suction pressure area of the compressor, the bypass channel can selectively provide communication and communication failure, a firstbackpressure cavity and a second backpressure cavity are formed on the side, back to the movable scroll part, of the fixed scroll part, the first backpressure cavity communicates with the first compression path through a first backpressure channel, and the second backpressure cavity communicates with a second compression path through the second backpressure channel.

Description

technical field [0001] The present invention relates to a scroll compressor. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] In a scroll compressor, the fixed scroll and the movable scroll respectively have an end plate and a wrap, and the wrap of the fixed scroll and the wrap of the movable scroll mesh with each other to form a gap between the wraps. series of compression chambers. As the movable scroll revolves around the fixed scroll, the compression chamber moves from the suction port on the radially outer side to the exhaust port on the radially inner side and its volume decreases, thereby realizing the compression of the working medium. [0004] In the scroll compressor of the prior art, when there is an excessive gap (tooth tip clearance) between the tip of the wrap tooth of any scroll member and the end plate of the other scroll member, it...
