FILTER APPARATUS AND EXTRUDER

摘要

PROBLEM TO BE SOLVED: To provide a filter apparatus which can efficiently remove easily deformable foreign matter without causing large increase in pressure drop and to provide an extruder using the filter apparatus. SOLUTION: The filter apparatus is provided with a mesh filter 5 for filtering fluid and a holder 6 for nipping the mesh filter. The holder 6 is constituted of an introducing side holder 7 having an introducing path 7a for introducing the fluid to the mesh filter 5 and a derivation side holder 8 having a derivation path 8a for deriving the fluid after passing through the mesh filter 5. Further, the introducing path 7a and the derivation path 8a are formed at mutually shifted positions via the mesh filter 5. COPYRIGHT: (C)2006,JPO&NCIPI
