Abstract

Disclosed is an electromagnetic valve in which a force due to a working fluid from an inflow hole acting perpendicularly with respect to the axis of a shut-off valve is reduced to thereby reduce the sliding resistance of the shut-off valve. An electromagnetic valve according to the present invention includes: a housing () having an inflow hole (), an inner flow path (), and a discharge hole (); a valve seat () secured in position inside the housing (); a shut-off valve () adapted to abut one surface of the valve seat () to shut off the working fluid flowing into the inner flow path () through the inflow hole (); and a pressure regulating valve () provided coaxially with the shut-off valve () and adapted to control, through adjustment of the dimensions of a gap between itself and the other surface of the valve seat (), the amount of working fluid flowing to the exterior of the housing () through the discharge hole (). In the electromagnetic valve, the housing () is equipped with a whirling member for causing the working fluid having flowed into the inner flow path () through the inflow hole () to whirl in one direction.
