Electromagnetic valve

An electromagnetic valve comprising:

• a fixed core;
• a movable core disposed so as to advance and retreat relative to the fixed core;
• a coil which generates a magnetic field which causes the fixed core and the movable core to attract each other;
• a valve body disposed so as to move together with the movable core;
• and
• a valve seat member comprising:
• a funnel-shaped valve seat surface which closes a flow path by being brought into abutment with the valve body and
• an inlet path formed in a bottom of the valve seat surface,
• wherein fluid flows from the inlet path towards the valve body side,
• the flow path is opened and closed by retreat and advance of the valve body relative to the valve seat surface,
• the valve body comprises:
• a semi-spherical seal portion;
• and
• a stem portion which extends from the seal portion towards the movable core,
• wherein a diameter of an end portion of the seal portion at the stem portion side is larger than a diameter of an end portion of the stem portion at the seal portion side, and
• a space into which the fluid flows out is defined in an area which is located on an extended line extending from a small diameter end portion to a large diameter end portion of the valve seat surface.
