Claims

[Scope of utility model registration request]

A valve chamber 43 is formed between a fixed core 45 and a yoke 46 that are coupled together to form a housing 44, and a movable core 51 is housed within the valve chamber 43 so as to be able to move toward and away from the fixed core 45. A return spring 52 is interposed between the fixed core 45 and the movable core 51 and exerts a spring force in a direction to move the movable core 51 away from the fixed core 45. A valve seat member 57 is provided facing the valve seat member 57, a valve body 42 that can be seated on the valve seat member 57 is fixed to the movable core 51, and a passage 55 communicating with the valve chamber 43 is bored in the other of the fixed core 45 and the yoke 46. In the provided solenoid valve, the inner surface of the valve chamber 43 and the movable core 5
A solenoid characterized in that the distance d between the outer surfaces of the valve chamber 43 and the outer surface of the movable core 51 is set to 0.05 mm to 0.2 mm, and the surface roughness of the inner surface of the valve chamber 43 and the outer surface of the movable core 51 is set to 6.3 μm or less. valve.
