Abstract
Provided is an electromagnetic valve improved in terms of the sealing property of a shut-off valve with respect to a valve seat. An electromagnetic valve according to the present invention includes: a housing (10) having an inflow hole (11) and a discharge hole (13); a valve seat (15) secured in position inside the housing (10); a shut-off valve (16) adapted to come into contact with one surface of the valve seat (15) to shut off a working fluid flowing into the housing (10) through the inflow hole (11); a pressure regulating valve (17) provided coaxially with the axis of the shut-off valve (16) and adapted to control the amount of working fluid flowing to the exterior of the housing (10) through the discharge hole (13) by adjusting the dimension of a gap between itself and the other surface of the valve seat (15); a sleeve (18) fixed to the housing (10) and adapted to guide the shut-off valve (16) in the direction of the axis; and a guide portion (23) adapted to guide the pressure regulating valve (17) in the direction of the axis, in which the valve seat (15) is integrated with the sleeve (18) and fixed to the guide portion (23).
