Kind Code:
A1
Abstract:
Provided is an electromagnetic valve whereby durability can be improved, size can be reduced, and fluid leakage can be eliminated. This electromagnetic valve is provided with: a core (41) that generates a magnetic attractive force when excited due to energization of a coil (33); a spring (10) that generates a pressing force in the direction opposite to that of the magnetic attractive force generated in the core (41); a plunger (7) that moves due to the magnetic attractive force and the pressing force; a first valve body (93) that opens/closes a fluid path (105) due to the movement of the plunger (7); a second valve body (94), which opens/closes the fluid path (105) due to the movement of the plunger (7), and which forms, with the first valve body (93), an interface (15); and a seal member (95), which is provided at the peripheral end of the second valve body (94), and which is formed of an elastic body. The seal member (95) has a protrusion (98) on the interface (15) side, and the first valve body (93) has a tapered section (99), on which the protrusion (98) abuts.
