SOLENOID TYPE ELECTROMAGNETIC VALVE DEVICE

摘要

Provided is a solenoid type electromagnetic valve having a high-speed responsivity and enhanced durability, thereby the valve can be protected from the erosion damage due to cavitations without losing the high-speed responsivity. The solenoid type electromagnetic valve is configured such that an attraction force arises between an attracting side face of a solenoid core power supply body and an attracted side face of an armature which is facing the attracting side face when a current is conducted through a solenoidal coil, while the attraction force is released between the attracting side face and the attracted side face when the current conducted through the solenoidal coil is cut off, wherein at least one plate member 5 of nonmagnetic material comprising nonmagnetic stainless steel, aluminum alloy or ceramic material is fitted to the attracting side face 15 of the solenoid core power supply body 101, and fluid insulation resin is filled therein, thereby the fluid insulation resin is solidified and secures the plate member 5 thereto.
