<P>PROBLEM TO BE SOLVED: To provide a dust collector capable of fully suppressing variation in the regeneration degrees of a plurality of cylindrical filters arranged in a direction along the axis of an injector pipe while attaining cost reduction. <P>SOLUTION: An injection mechanism J includes a header tank 13, to which the opening end 11w side of the injector pipe 11 is connected, for storing compressed air H, and a communicating state switching means 14. The communicating state switching means 14 is switched into a communicating state between the opening end 11w of the injector pipe 11 and the inside of the header tank 13. The compressed air H stored in the header tank 13 is thereby injected into the injector pipe 11 from the opening end 11w. The inner diameter of the injector pipe 11 is constant, and at least one part in a direction along the axis in the injector pipe 11 is provided with an annular diameter reduced part R for applying resistance to the flow of the compressed air H flowing from the opening end 11w of the injector pipe 11 toward the blocked end 11s. <P>COPYRIGHT: (C)2013,JPO&INPIT |
