Title

SCROLL COMPRESSOR
(FR)
COMPRESSEUR À SPIRALE
(JA)
スクロール圧縮機
Abstract:
(EN)
A scroll compressor (1) is provided with: a stationary scroll (5), a turning scroll, a suction part, a discharge part, and an electric motor. A scroll end plate surface (5f) has formed thereon, at locations on the outer side of a lap (5a), a groove part (5g) recessed with respect to the end plate surface, and a flange part (5h) protruding with respect to the groove part. When a perfect circle (Lci) to be used as a reference is drawn using, as the radius, the distance (t) between the center point (O) of the scroll where the flange part is formed and a winding-end point (5m) of an involute curve of the scroll, the flange part (5h) is an area (R1) which remains after excluding, from an area (R0, R1) that protrudes from the perfect circle, an area (R0) that is contiguous with the winding-end point. This scroll compressor (1) improves reduction in sliding loss using a simple structure and simultaneously, improves overall reduction in leakage loss of refrigerant in a compression chamber.
(FR)
L'invention concerne un compresseur à spirale (1) pourvu : d'une spirale fixe (5), d'une spirale tournante, d'une partie d'aspiration, d'une partie d'évacuation et d'un moteur électrique. Une surface de plaque d'extrémité de spirale (5f) a formé sur ce dernier, à des emplacements sur le côté extérieur d'une nappe (5a), une partie de rainure (5g) en retrait par rapport à la surface de plaque d'extrémité, et une partie de bride (5h) faisant saillie par rapport à la partie de rainure. Lorsqu'un cercle parfait (Lci) à utiliser en tant que référence est dessiné à l'aide, en tant que rayon, de la distance (t) entre le point central (O) de la spirale où la partie de bride est formée et un point d'extrémité d'enroulement (5m) d'une courbe développante de la spirale, la partie de bride (5h) est une zone (R1) qui reste après exclusion, à partir d'une zone (R0, R1) qui fait saillie depuis le cercle parfait, d'une zone (R0) qui est contiguë au point d'extrémité d'enroulement. Ce compresseur à spirale (1) améliore la réduction de la perte de coulissement à l'aide d'une structure simple et, simultanément, améliore la réduction globale de la perte de fuite de réfrigérant dans une chambre de compression.
(JA)
スクロール圧縮機(1)は、固定スクロール(5)と、旋回スクロールと、吸込部と、吐出部と、電動機とを備えている。スクロールの鏡板面(5f)には、ラップ(5a)よりも外側の位置に、鏡板面に対して凹状の溝部(5g)と、溝部に対して凸状のつば部(5h)とが形成されている。つば部(5h)は、つば部が形成されているスクロールの中心箇所(O)からそのスクロールのインボリュート曲線の巻き終わり箇所(5m)までを結ぶ距離(t)を半径とする真円(Lci)を基準とし、その真円よりも外側にはみ出しているはみ出し領域(R0,R1)のうち、巻き終わり箇所に連続する領域(R0)を除外した残りの領域(R1)である。スクロール圧縮機(1)は、簡易的な構造で摺動損失の低減性を向上させるとともに、圧縮室全体での冷媒の漏れ損失の低減性を向上させることができる。
