Title:
METHOD FOR ARRANGING CYLINDRICAL FILTER AND FILTER
Document Type and Number:
Japanese Patent JPH1190121
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To make the most of the advantage that a cylindrical filter is easily set and to effectively arrange the filter around a cylinder main body having plural through-holes. SOLUTION: The cylindrical filter 70 is provided with a metallic mesh 72 and a resin supporting frame 74 for reinforcing the mesh 72. The frame 74 is composed of a couple of annular frames 741 and 742 positioned on the periphery of the mesh 72 and five connecting frames 745 connecting the annular frames. The adjacent connecting frames 745 are circumferentially separated from each other to demarcat five exposed windows 700. The four through-holes 300 of the cylinder main body 62 are circumferentially arranged at regular intervals, and the arranging pitch of the windows 700 of the filter 70 surrounding the main body 62 is made different between the upper half and lower half. Consequently, all the four through-holes 300 are never closed by the connecting frames 745 even when the filter 70 is circumferentially moved around the main body 62.
