Abstract

A scroll fluid machine comprises a housing having a fixed scroll and an orbiting scroll revolved by a driving shaft which is driven by a motor behind the housing. A blowing fan is provided between the orbiting scroll and the motor. Rotation of the fan causes decompression in the housing to allow primary external air to be sucked from the outside into the housing through a primary sucking hole. Secondary external air is introduced from a secondary sucking hole and mixed with the primary external air of the scroll fluid machine to cool the parts of the scroll fluid machine in the housing and/or the motor.
