<p>PURPOSE:To improve volumetric efficiency by providing first and second suction ports which connect suction chambers to low pressure spaces respectively, in positions close to the outer peripheral end parts of both movable and fixed scroll blades of a fixed element and uniformly introducing a gas into said two compression chambers. CONSTITUTION:A first suction pipe 182 is provided in a position close to the outermost peripheral end part of the movable scroll blade 123 of a fixed element while a second suction pipe 183 is provided in a position close to the outermost peripheral end part of the fixed scroll blade 115 of the fixed element. Since the second suction pipe 183 is positioned at the inlet part of a second compression chamber P2, a gas which is introduced from the first suction pipe 182 to a first compression chamber P1 is sucked in at the same rate as a gas which is introduced from the second suction pipe 183 to the second compression chamber P2, compressing symmetrical positions to the same degree. That is, a gas can be uniformly introduced to both of the compression chambers P1, P2, improving volumetric efficiency.</p> |
