Claims

[Claims for Utility Model Registration] 1. A fixed scroll that forms a first wrap in a concave space surrounded by a peripheral wall provided with a port that functions as an inlet or an outlet; and a fixed scroll that fits into the first wrap. an orbiting scroll having a possible second lap, the scroll configured to be able to change the volume of a sealed space formed between the two laps by causing the orbiting scroll to revolve around a fixed scroll without rotating on its axis. In the fluid machine, a conduit that communicates with the port is formed in an area outside the sliding surface of the concave space in which the second lap slides, and the conduit opening is connected to the second lap.
A scroll fluid machine characterized in that the scroll fluid machine is configured to be able to directly face the circumferential surface of the first wrap located inside the wrap beyond the winding end of the wrap. 2. The scroll fluid machine according to claim 1, wherein the guide path is a recess formed along the inner peripheral surface of the peripheral wall of the fixed scroll. 3. In an oil-free scroll fluid machine in which a sealing member made of a self-lubricating resin is attached on the peripheral wall joint surface that contacts the orbiting scroll, the recess does not open to the joint surface and is located below the joint surface. The scroll fluid machine according to claim 2, wherein the scroll fluid machine is formed along the inner circumferential surface of the peripheral wall.
