Abstract (en)

[origin: EP1500820A1] There is provided a rotary compressor in which a coil spring is provided to press a vane against a roller, and the contact area between the vane and a vane groove is secured by a simple and inexpensive construction, whereby the compressor size is decreased while the leakage of working fluid is restrained. <??>The rotary compressor includes a closed vessel 1; a cylinder 4 having a vane groove 4a, which is located in the closed vessel 1; a shaft having an eccentric portion 5a; a roller 6 which is rotatably fitted on the eccentric portion 5a of the shaft to eccentrically rotate in the cylinder 4; a vane 7 provided in the vane groove 4a in the cylinder 4 to reciprocate in the vane groove 4a while a tip end thereof is in contact with the roller 6; and a coil spring 20 for pressing the vane 7 against the roller 6. The vane 7 is provided with a spring hole 7d on the side opposite to the side on which the vane 7 is in contact with the roller 6, and the spring hole 7d contains at least a part of the coil spring 20. <IMAGE>
