    摘要: An electromagnetic valve (100) which can ensure a predetermined response behavior while sustaining a desired control performance with operation noise being suppressed even after operation over an extended time includes a plunger assembly (15) having a plunger (7), a coil (2) for driving the plunger (7), a fixed core (4) disposed in a direction in which the plunger (7) is displaced for attracting the plunger assembly (15) to a retracted position upon electrical energization of the coil (2) to thereby hold the plunger at that position, a resilient member (8) disposed, being compressed, between the plunger (7) and the fixed core (4) to resiliently urge the plunger assembly (15) to an advanced position, and a spacer (9; 39) interposed between the plunger (7) and the fixed core (4). The spacer (9; 29; 39; 49) is provided with a protrusion (9a; 29a).

    摘要: 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.
