PURPOSE:To eliminate blinding without stopping a machine operation by removably inserting pins constituting a flow adjusting section into holes communicating the primary and secondary ports. CONSTITUTION:The primary port 9 and secondary ports 10, 10 are communicated by holes 11, 11. A pin 14 constituting a flow adjusting section is removably inserted into each hole 11. One end of it penetrates a guide hole 12 and protrudes to the outside of a main body 8 and is fitted to the moving section 15a of a solenoid 15, and the pin 14 is extracted from the hole 11 by the absorption of the solenoid 15. A filter 18 arranged at the secondary side recovers the attached objects flowing through the hole 11 when the pin 14 is extracted. Blinding is detected by a flow sensor arranged in a lubricating oil pipeline, then the solenoid 15 is operated and sludge in the oil is removed. |
