Abstract

PURPOSE:To achieve the maximum suction gas capacity in spite of the small radius of revolution and the reduced number of turn, by forming the spiral shape of each spiral member such that it is connected linearly to a developed line or an arch. CONSTITUTION:The spiral shape of a fixed spiral member 1 or a movable spiral member 2 is constructed such that a linear line is connected to a developed line. Assuming the middle drawing is the spiral formed with the basic developed line while the lower drawing is the spiral of the invention assembling the linear line, the number of the spiral is two in both case having same movable scroll diameter, and the maximum suction gas capacity in each drawing is as shown by the slant, and when employing the linear line in the spiral and lengthening the length of the linear section in the spiral the maximum suction gas capacity can be increased without increasing the number of turn of the spiral nor the radius of the revolution.
