ABSTRACT:
A scroll fluid machine comprises fixed and orbiting scrolls. The fixed scroll has a fixed end plate having inner and outer fixed wraps and the orbiting scroll has an orbiting end plate having inner and outer wraps. Between the fixed and orbiting end plates, an annular partition wall is provided. The orbiting scroll is driven by an eccentric portion of a driving shat to form an inner compressing chamber in which the inner fixed wrap is engaged with the inner orbiting inside the annular partition wall and to form an outer compressing chamber in which the outer fixed wrap is engaged with the outer orbiting wrap between the annular partition wall and a housing. The inner compressing chamber communicates with a rear pressure chamber behind the orbiting end plate thereby preventing the orbiting end plate from being deformed or distorted.
