Abstract (en)
[origin: EP2703648A1] Provided is a scroll compressor which can enhance the strength of an end plate facing a through-hole in the vicinity of the base of the lap tip portion of a fixed scroll and hence provide enhanced reliability and durability. A concave curved surface S32 of a non-involute surface S3 formed between the start point P of an inner involute surface S1 constituting a lap 23B of a fixed scroll 23 and the start point Q of an outer involute surface S2 is formed in a curved surface shape having a smaller radius of curvature. The opening shape of the periphery of a through-hole 23C in a close region µ facing the concave curved surface S32 is formed with a curved surface having a smaller radius of curvature than the radius r of curvature of the concave curved surface S32, the through-hole being formed at the spiral center or the tip portion of the lap 23B of the fixed scroll 23. A distance to hole L is ensured to be as long as possible, where the distance to hole L is the length between the base of a vertex Z of the convex curved surface S32 of the non-involute surface S3 and a maximum proximity edge U of the through-hole 23C facing the base of the lap tip portion Z.
