ABSTRACT:
A vane compressor capable of obtaining a two stage compression. The compressor has a front and rear rotor 6a and 6b for defining, together with a cylinder bores 43 and 44, first and second operating chambers 39 and 40, respectively. A refrigerant from a first inlet opening 28 is sucked into the first operating chamber 39 by a rotation of the front rotor 6a for obtaining a first stage compression at the first chamber 39. The refrigerant is then introduced, via an intermediate pressure chamber 36, to the second operating chamber 40 for obtaining a second stage compression at the second chamber 40, which is discharged outwardly.
