Abstract: PURPOSE:To facilitate the one control of air-tightness without requiring a conventional side block by providing a cylinder head, which can be fitted to both open ends of a cylinder and which flows the gas to be compressed/the compressed gas into/out from a compression chamber formed by a rotor, a vane and the cylinder. CONSTITUTION:Since cylinder heads 2, 3 are directly provided in the open ends of a rotor 4, when a driving shaft 9 is rotated, the rotor 4 and a vane 11 provided in the rotor 4 are rotated, and at the time of suction process, the gas to be compressed is supplied to a compression chamber 12 through the cylinder head 2, and at the time of compression process, the compressed gas is flowed out from the compression chamber 12 to the cylinder head 3. A cylinder head to be used at this stage has a part, which is equivalent to a conventional side block, and a compressor is finished by incorporating this cylinder block to a cylinder 1, in which the rotor 4 and the vane 11 are housed. Consequently, seal material is not necessary to facilitate the control of air-tightness.

Abstract: PROBLEM TO BE SOLVED: To make a polishing process unnecessary, and to prevent the deformatin of a sliding face of a swash plate, by performing the surface treatment by the gas nitrosulphurizing treatment, or electroless Ni-P-B plating, onto the swash plate and a projecting part which forms a part of a link mechanism mounted on the swash plate. SOLUTION: In a variable capacity swash plate compressor, a thrust flange 40 for transmitting the rotation of a shaft 5 to a swash plate 10, is fixed on a front side edge of the shaft 5, the thrust flange 40 and the swash plate 10 are connected through a link mechanism 41 in which a point part 43a of a rod is fitted in a guide groove 10f formed on a bracket (projecting part) 10e in such manner that it is relatively slidable, and the swash plate is mounted in such manner that it can be inclined to a face vertical to the shaft 5. On this occasion, the surface treatment is performed onto the swash plate 10 and the projecting part 10e by the gas nitrosulphurizing method or the electroless Ni-P-b plating method. Thereby the surface of the swash plate 10 and the projecting part 10e are hardened, and the abrasion resistance, the lubricating characteristics and the durability can be improved.

Abstract: PURPOSE: To prevent seizure without increasing weight and cost by forming a vane of a vane type compressor to rotate while rubbing an inner peripheral wall of a cam ring out of an aluminium type base material and an iron type covering part to cover a surface of its base material. CONSTITUTION: A vane 14 of a vane type compressor which is slidably inserted into a vane groove of a rotor in a cam ring and whose tip rotates while rubbing an inner peripheral wall of the cam ring by jumping out of the vane groove when the rotor rotates, is formed of an aluminium type base material 14a and an iron type covering part 14b to cover its surface. When the vane 14 is manufactured by a drawing construction method, a bar-shaped aluminium type base material 34a is inserted into an iron pipe 34b being the covering part 14b, and only the iron pipe 34b is heated to 200 to 300 deg.C or more by a heater 20, and is thermally expanded. Next, the iron pipe 34b and the base material 34a are inserted into a hole 21a of a die 21, and the iron pipe 34b is drawn out while blowing a cold blast against it.

Abstract: PROBLEM TO BE SOLVED: To prevent the deformation of a vane, caused by the difference in a coefficient of thermal expansion between a coating part and a matrix, and eliminate the preservation treatment applied to the surface of the coating part, by coating the surface of the aluminium matrix with the stainless coating part. SOLUTION: A rod-like part 34a being a material of an aluminium series matrix 14a is inserted in a stainless pipe 34b being a coating part 14b, only the stainless pipe 34b is heated up to 200 deg.C or more by a heater 20 so as to be thermally expanded, the stainless pipe 34b and the aluminium series matrix 34a are inserted in the hole 21a of a die 21, and the stainless pipe 34b is pulled out while blowing cold air. Thusly, the stainless coating part 14b is coated on the surface of the aluminium matrix 14a. Hereby, the deformation of a vane 14 can be prevented which is caused by difference in the coefficient of thermal expansion between the coating part 14b and the matrix 14a, and the preservation treatment applied to the surface of the coating part 14b can be eliminated.
