Patent ID: 8186379

Claim:
An electromagnetic valve comprising: a valve unit having; an electromagnetic coil for generating magnetic field when electric current is supplied thereto; a yoke made of magnetic material and accommodating the electromagnetic coil; a stator core arranged at its one end in an inner periphery of the electromagnetic coil, the other end of the stator core being outwardly protruding from an end of the yoke; and an armature made of magnetic material and arranged in the inner periphery of the electromagnetic coil in such a manner that the armature slides in an axial direction of the electromagnetic coil, so that the armature is attracted toward the stator core when the electric current is supplied to the electromagnetic coil; a sensor attached to a protruding end of the stator core for detecting at least one of a condition of the valve unit and a condition of fluid filled in the valve unit; a magnetic flux limiting portion formed in the stator core on a side of the protruding end toward the sensor for suppressing magnetic flux flow to the sensor, wherein the magnetic flux limiting portion outwardly protrudes away from the end of the yoke toward the sensor.
