ル型流体機械。 A pair of fixed scrolls each having a spiral wrap erected on the end plate and an orbiting scroll are interlocked with each other and are rotatably housed in a boss protruding from the center of the outer surface of the end plate of the orbiting scroll. In a scroll type fluid machine, an eccentric pin of a rotating shaft is connected to a driven bushing, a balance weight is provided on the drive bushing, and a sub-balance weight is provided on the rotating shaft,
The rotary shaft itself is provided with the function of the sub-balance weight by providing one or more recesses in the boss portion for supporting the rotary shaft with a bearing. Scroll type fluid machine.
