Abstract
In a scroll air compressor as a scroll fluid machine capable of being downsized with an increased cooling effect, cooling air entering through a fixed inlet of a fixed cooling passage provided at the rear of a fixed scroll, and an orbiting inlet of an orbiting cooling passage provided at the rear of an orbiting scroll, is allowed to flow out of an fixed outlet and an orbiting outlet, respectively. Thereafter, the cooling air is guided to an outer periphery of the other end of the casing through a side duct and a guide duct, and then sucked into an inner peripheral side of a centrifugal fan to be discharged outwardly from an exhaust port provided in a fan cover.
