SOLENOID VALVE

摘要

Disclosed is a solenoid valve which can minimize foreign materials included in fluid of a valve which flows in a solenoid. The solenoid valve includes a solenoid, a valve operated by the solenoid, and a plate filter disposed between the solenoid and the valve. The valve includes a hollow holder having one or more chambers and ports formed therein, and a spool reciprocating upwards and downwards within the holder by the solenoid. In addition, the plate filter includes an outer ring fixed to the holder, an inner ring fixed to the spool, and a filter membrane formed between the outer ring and the inner ring. The plate filter is disposed between the solenoid and the valve so that foreign matter included in the fluid flowing into the solenoid can be minimized. When a through-hole is formed in the solenoid and a column filter is provided to the solenoid, operational resistance due to change in internal pressure of the solenoid can be reduced and heat can be discharged from the solenoid to the outside during movement of a plunger.
