SCROLL COMPRESSOR

To efficiently separate mist oil contained in discharge gas while improving efficiency of a compressor by reducing heat transfer from the discharge gas to a fixed scroll.SOLUTION: A scroll compressor comprises a fixed scroll including a fixing base plate and a discharge port. A discharge cover is provided to cover an upper side of the discharge port, and the discharge cover comprises: a projection including an inclined plane and a collision surface; a flange connected to a lower part of the inclined plane; a ground which protrudes downward from a portion of the flange and is fixed to the fixing base plate; and an opening which is formed on a bottom face of the flange. When a point on a boundary line between the inclined plane and the collision surface is defined as P, a collision center of the collision surface is defined as O, a fixing point defined on the boundary line is defined as Q and a straight line connecting the point P and the collision center O is defined as OP, regarding the boundary line, sections in each of which a length of the straight line OP is increased in a monotonous manner as the point P is closer to the fixing point Q along the boundary line exist at both sides with the fixing point Q interposed therebetween.SELECTED DRAWING: Figure 1 【課題】吐出ガスから固定スクロールへの伝熱を低減して圧縮機の効率を向上しつつ、吐出ガスに含まれるミスト油を効率良く分離する。【解決手段】スクロール圧縮機は、固定台板及び吐出口を有する固定スクロールを備える。また、吐出口の上方を覆うように吐出カバーが設けられ、吐出カバーは、傾斜面及び衝突面を有する凸部と、傾斜面の下部に接続された鍔部と、鍔部の一部から下方に突出して固定台板に固定される接地部と、鍔部の下面に形成される開口部を備える。傾斜面と衝突面との境界線上の点をＰ、衝突面の衝突中心をＯ、境界線上に定めた固定点をＱとし、点Ｐと衝突中心Ｏを結ぶ直線をＯＰとしたとき、境界線は、点Ｐが境界線上に沿って固定点Ｑに近づくにつれて直線ＯＰの長さが単調に増加する区間が固定点Ｑを挟んで両側にそれぞれ存在する。【選択図】図１
