<p>The control valve has a valve core and a valve seat in orifice (36a). An armature in a shell is moved forward and backward by an exciting coil. A plunger in the core selectively opens and closes the orifice by the armature operation. A relief spring (41) in the plunger pushes a closing membrane (40) to selectively open and close the orifice when an oil pressure increases above a predetermined pressure.</p> |
