Claims

[Scope of utility model registration request]

a casing, a drive shaft which is rotatably supported by the casing and whose tip end extending into the casing is eccentric and serves as a crankshaft; an orbiting scroll having a wrap portion erected thereon; a fixed scroll provided on the casing and having a spiral wrap portion erected on the end plate to form a sealed space between the wrap portion of the orbiting scroll; In a scroll fluid machine comprising a suction port bored on the radially outer side of the scroll and a discharge port bored on the axial center side, there is a space between the lap side surface of the orbiting scroll and the lap side surface of the fixed scroll. A scroll fluid machine characterized in that a cylindrical body eccentric by the same amount as the eccentricity of the crankshaft is positioned outside the suction port and fitted in an air-liquid tight manner.
