Patent ID: 8857789

Claim:
An electromagnetic solenoid valve comprising: a valve body having an end part, the valve body being configured to open and close a liquid passage; an armature plate connected to the end part of the valve body; and a solenoid core power supply body comprising a solenoidal coil integrated with a solenoid core in a solenoid case that is filled with a liquid, wherein the electromagnetic solenoid valve is configured such that an attracting side face of the solenoid core power supply body attracts an attracted side face of the armature plate when current is conducted through the solenoidal coil, while an attraction force between the attracting side face of the solenoid core power supply body and the attracted side face of the armature plate is released when the current conducted through the solenoid coil is cut off, wherein an insulation resin is disposed at a side of the attracting side face of the solenoid core power supply body and at least one plate member of nonmagnetic material is disposed at an outer side of the insulation resin so that the at least one plate member is at a facing side of the attracting side face of the solenoid core power supply body so as to bypass the insulation resin and face the armature plate, the at least one plate member having a higher softening point and a higher hardness than the insulation resin, wherein the at least one plate member of nonmagnetic material has an outermost periphery and a surface facing the attracted side face of the armature plate, the surface being a planar surface extending over an entirety of an area defined by the outermost periphery, and wherein the surface of the at least one plate member of nonmagnetic material is free from resin.
