Title:
ROTARY COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2019/022415
Kind Code:
A1
Abstract:
A rotary compressor according to the present invention has vane slots, into which vanes are glidingly inserted, respectively formed on a cylinder, and has a suction port, which is formed at one side of the vane slot in a circumferential direction, for guiding fluid into at least one compression chamber, wherein the suction port is formed to be engraved in a radial direction such that an end portion of the suction port, coming in contact with the inner peripheral surface of the cylinder, forms a slot shape. Therefore, the circumferential length of the suction port is reduced such that a compression starting time can be made to be earlier, and a partition part between the suction port and the vane slot has elasticity so as to enable the vane to be restrained from coming in close contact with the vane slot.
