Abstract

PROBLEM TO BE SOLVED: To prevent back-flow of foreign matters to a filter part and to prevent clogging of the filter part by communicating an inlet side part of the filter part with a sucking room of an ejector and sucking and removing the collected foreign matters. SOLUTION: A foreign matters removing port 18 is provided on a place communicated with the inlet 1 and is connected to a suction room 21 of the ejector 5 via a communicative pipe 19 and a valve 20. The ejector 5 is formed by connecting a nozzle in the inside of the suction room 21 to a fluid feed pipe 6 via a pipe 22, and also connecting to a left side diffuser 23 of the suction room 21. The fluid allowed to flow in from the inlet 1 is circulated with a guide blade member 10 and foreign matters having large mass reach an annular space 9 from the outside of a passage 8 to be collected, and also foreign matters having small mass are collected with a filter 13 and the liquid flows down to the outlet 2. The foreign matters collected at the outer peripheral surface of the filter 13 and the foreign matters collected into the annular space 9 are sucked into the suction room 21 by feeding the fluid to the ejector 5 to generate a necessary suction force to the suction room 21, and remove them to the outlet.
