Title: Vane type compressor
Inventor: SUZUKI SHINICHI
IPC: C21D1/78
Filed: 1988-11-09
Abstract: PURPOSE:To obtain a compressor which is lightweight and possesses the superior abrasion resistance by forming a rotor and a cylinder from the Al group material and forming a boron hardened layer from a basic plate having a pearlite structure in almost all parts of the surface of a vane. CONSTITUTION:A rotor 4 and a cylinder 1 are made of Al group material, and a vane 6 is constituted of a basic plate 60 which contain carbon in 0.7wt.% or more and consists of pearlite structure in almost all the part and a boron hardened layer 61 at least on one part of the basic plate 60. When the vane 6 is installed onto the compressor, and the compressor is driven, the weight can be reduced, and the superior abrasion resistance can be obtained, since the rotor 4 and the cylinder 1 are made of Al group material, and the abrasion of the vane 6 can be prevented, since the surface of the vane 6 is formed of the boron hardened layer 61 which has the sufficient hardness in comparison with the rotor and cylinder. Then, even if the collision due to chattering is generated, the deformation of the vane 6 is prevented, since the inner hardness of the vane 6 is high, and the use for a long period is permitted.
