摘要：
A scroll type fluid machinery which is provided with: a first scroll and a second scroll which moves with respect to the first scroll, where the base of the first scroll is provided with suction bores perforating through the base from the rear surface thereof to the front surface, and open at the outer peripheral portion of the front surface of the base, so that fluid released into an internal space of the body casing passes through the suction bores, and into the suction sides of compression volumes formed between spiral members of the scrolls, whereby suction pressure in the compression volumes is maximized and volumetric efficiency is improved.
