Abstract
An electromagnetic valve has an electromagnetic coil supported by a cylindrical yoke, a movable armature within a sleeve, a stator core fixed to one end of the sleeve, wherein one end of the stator core protrudes from an end of the yoke. A pressure sensor is attached to a protruding end of the stator core. A magnetic flux limiting portion is formed in the stator core at such a position which is on a side of the protruding end of the stator core toward the pressure sensor. A magnetic flux flow to the pressure sensor is limited by the magnetic flux limiting portion, so that a precise detection by the sensor can be achieved even when the sensor is arranged closer to the electromagnetic coil.
