阅读说明：本技术 涡旋压缩机 (scroll compressor having a plurality of scroll members ) 是由 村上泰弘 水嶋康夫 中井亮太 于 2018-05-25 设计创作，主要内容包括：本发明提供一种涡旋压缩机。固定涡旋齿(52)包括涡卷状的固定涡卷部(57)以及具有圆弧形状的固定圆弧部(58)。可动涡旋齿(62)包括涡卷状的可动涡卷部(67)以及具有圆弧形状的可动圆弧部(68)。圆弧部侧面间隙(GA)由固定圆弧部(58)、以及可动涡卷部(67)或可动圆弧部(68)形成,或者由可动圆弧部(68)、以及固定涡卷部(57)或固定圆弧部(58)形成。涡卷部侧面间隙(GI)由固定涡卷部(57)和可动涡卷部(67)形成。圆弧部侧面间隙(GA)大于涡卷部侧面间隙(GI)。(The invention provides a scroll compressor. The fixed wrap (52) includes a spiral fixed wrap portion (57) and a fixed arc portion (58) having an arc shape. The movable spiral wrap (62) includes a spiral movable spiral wrap portion (67) and a movable arc portion (68) having an arc shape. The arc portion side Gap (GA) is formed by the fixed arc portion (58) and the movable scroll portion (67) or the movable arc portion (68), or formed by the movable arc portion (68) and the fixed scroll portion (57) or the fixed arc portion (58). The scroll side surface Gap (GI) is formed by a fixed scroll part (57) and a movable scroll part (67). The arc portion side surface Gap (GA) is larger than the scroll portion side surface Gap (GI).)

1. A scroll compressor (10) is provided with:

A fixed scroll (50) having a fixed wrap (52); and

A movable scroll (60) having a movable wrap (62),

The fixed scroll wrap (52) includes:

A spiral fixed spiral part (57); and

A fixed arc part (58) having an arc shape with a smaller curvature radius than the fixed wrap part,

The movable spiral wrap (62) includes:

A movable spiral part (67) having a spiral shape; and

A movable arcuate portion (68) having an arcuate shape with a smaller curvature radius than the movable spiral portion,

An arc portion side Gap (GA) is formed by the fixed arc portion (58) and the movable scroll portion (67) or the movable arc portion (68), or by the movable arc portion (68) and the fixed scroll portion (57) or the fixed arc portion (58),

the scroll side surface Gap (GI) is formed by the fixed scroll part (57) and the movable scroll part (67),

The arc portion side Gap (GA) is larger than the wrap portion side Gap (GI).

2. The scroll compressor of claim 1,

The ratio (GA/GI) of the arc-shaped part side Gap (GA) to the scroll part side Gap (GI) is 1.2 or more.

3. The scroll compressor of claim 1 or 2,

At least one of a ratio (TAF/TIF) of a Thickness (TAF) of the fixed arc portion to a Thickness (TIF) of the fixed wrap portion and a ratio (TAM/TIM) of a Thickness (TAM) of the movable arc portion to a Thickness (TIM) of the movable wrap portion is 1.2 or more.

4. The scroll compressor of any one of claims 1 to 3,

The side Gap (GI) of the scroll part is the larger one of the side gap of the A chamber and the side gap of the B chamber,

The A-chamber side clearance is formed by an inner line (53) of the fixed wrap and an outer line (64) of the movable wrap,

the B chamber side clearance is formed by an outer line (54) of the fixed wrap and an inner line (63) of the movable wrap.

5. The scroll compressor of any one of claims 1 to 4,

The fixed scroll further has a fixed loose part (59) adjacent to the fixed wrap at an end opposite to the fixed arc part, or,

The movable scroll further has a movable loose part (69) adjacent to the movable wrap at an end opposite to the movable arc part,

The loosening part side Gap (GL) is formed by the fixed loosening part (59) and the movable volute part (67) or the movable loosening part (69), or formed by the movable loosening part (69) and the fixed volute part (57) or the fixed loosening part (59),

The loosening part side Gap (GL) is larger than the scroll part side Gap (GI).

6. the scroll compressor of any one of claims 1 to 5,

The refrigerant is configured to be compressed, the discharge temperature of which is higher than that of R410A.
