Abstract

L'invention se rapporte à un spiral (1) comportant une lame (3) enroulée sur elle-même selon plusieurs spires (PI, PE), la spire interne (PI) étant venue de forme avec une virole (5) comportant une bande (7) s'étendant sensiblement sous forme d'un polygone. Selon l'invention, le contour externe au niveau de chaque renflement (2, 4, 8) des sommets du polygone comporte deux parois (21-22, 41-42, 81-82) s'étendant axialement sensiblement parallèlement entre elles par rapport au segment formé entre le centre (C) de la virole (5) et l'extrémité (S1, S2, S3) de dudit renflement (2, 4,8).

The invention relates to a spiral (1) comprising a blade (3) wound on itself in several turns (P I , P E ), the inner coil (P I ) being shaped with a ferrule (5) having a band (7) extending substantially in the form of a polygon. According to the invention, the outer contour at each bulge (2, 4, 8) of the vertices of the polygon comprises two walls (2 1 -2 2 , 4 1 -4 2 , 8 1 -8 2 ) extending axially substantially parallel to each other with respect to the segment formed between the center (C) of the shell (5) and the end (S 1 , S 2 , S 3 ) of said bulge (2, 4.8).
