Claims

[Scope of utility model registration request]

It has a casing with a bearing part on one side and a scroll fitting hole on the other side, a cylindrical part that fits into the fitting hole of the casing, a spiral wrap part erected on the end plate, and a fixing member fixed to the casing. a scroll, a drive shaft which is rotatably provided in a bearing part of the casing and has a crank at its tip; and a drive shaft which is rotatably supported by the crank and whose outer peripheral side of the end plate is connected to the scroll fitting hole of the casing and the cylindrical part of the fixed scroll. and an orbiting scroll which is sandwiched between the fixed scroll and has a spiral wrap section erected on the end plate, which forms a compression chamber while rotating while overlapping and slidingly contacting the wrap section of the fixed scroll. In the machine, the annular chamber formed by the scroll fitting hole of the casing, the cylindrical portion of the fixed scroll, and the outer peripheral end surface of the end plate of the orbiting scroll is connected to the crank chamber formed between the back side of the orbiting scroll and the casing. A scroll compressor characterized by being connected to.
