PROBLEM TO BE SOLVED: To provide a solenoid valve which can reduce the man hour of dimensional control and secure the flow path area on a filter. SOLUTION: In the solenoid valve installed in the purge passage of an evaporation fuel treating apparatus, an integrated filter 70 is resin molded integrally with a valve seat 4. The integrated filter 70 is disposed between an inlet flow path 32 and an outlet flow path 38 to capture a foreign substance 99 mixed into a fluid with a mesh portion 71. Integral molding allows the contact place that requires dimension control to be reduced and the dispersion in the dimension to be controlled in less man hour. Further, since the arrangement of ribs 74a to 74d is settled, the dispersion in the flow rate is suppressed. Furthermore, since the foreign substance 99 is laterally divided by the rib 74a disposed in a position where the flow Sa of the fluid collides and is deposited, it is not relatively deposited in the mesh portion 71 region near the rib 74a. Thus, the flow path area on the filter is secured. COPYRIGHT: (C)2011,JPO&INPIT |
