ABSTRACT:
An electromagnetic valve of a reduced size capable of suppressing temperature rise of a coil regardless of continuous electrical energization over an extended time while preventing attracting force from lowering includes a coil cooling fluid passage (9a;8a;4a) for communicating a coil cooling fluid sump space (2a) with a controlled pressure region for allowing a fluid to flow into the coil cooling fluid sump space (2a) from the controlled pressure region. The coil cooling fluid passage includes a small-diameter communicating passage portion (9a) provided so as not to exert influence to a hydraulic pressure prevailing in the controlled pressure region.
