PURPOSE:To realize prevention of a jumping phenomenon of a vane by providing a corrugated spring made of superelastic alloy in the deepest part of a slit, in a vane type compressor for cooling a car or the like. CONSTITUTION:In a cylinder 11, which has an intake hole 12 and a discharge hole 13, a rotor 14 is eccentrically arranged inside so that it may approach those holes at an approaching part 15, while the plural number of radial slits 16 are formed in said rotor 14 and a corrugated spring 17 made of superelastic alloy is fitted to a holding implement 18 at the deepest part of said slit, to be inserted in said slit, and a vane 19 protrudes from and retracts in said slit. When the vane 19 retreats completely in the slit 16, the upper half of the corrugated spring 17 is largely deformed and shows its largest spring force. On the other hand, the condition of the lower half of the rotor 14 is such that the vane 19 protrudes by the biggest stroke and the spring force of the corrugated spring 17 does not work. Thus, generation of a jumping phenomenon of the vane at the time of its passing by the approaching part 15 can be prevented, and a spring with excellent durability can be designed. |
