<p><P>PROBLEM TO BE SOLVED: To suppress degradation of efficiency of a compressor by reducing dead volume caused by installation of an injection mechanism (70), suppress increase in the size of a compression mechanism (20) and increase in cost and secure sufficient injection amount, in the rotary compressor. <P>SOLUTION: The injection mechanism (70) is installed in a middle plate (21), and an injection passage (71) is formed in the radial direction of cylinders (41, 51). The rotary compressor includes a slide mechanism (75) opening/closing injection ports (72a, 72b) communicating the injection passage (71) with cylinder chambers (25, 26) by a slide valve (73). When the injection ports (72a, 72b) are opened, the slide valve (73) retracts from the injection ports (72a, 72b) so as not to be located within the injection passage (71). <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
