The subject innovation is intended to provide a direct-acting solenoid valve according to a new form to achieve the improvement of the plunger and sealing by improving the coupling structure of the valve seat that is coupled thereto.
To this end, the subject innovation is to as formed from a pipe structure opens into the upper and lower bottom valve made in addition to stars provide a fluid through the fluid inlet tube through the opening portion of the upper is provided with an orifice for outlet of fluid to the fluid outlet tube body; And, the valve seat is formed so as to cover the open upper surface of the orifice which forms the valve body for opening and closing the orifice, it is at the bottom, with moved elastically lifting with my bobbin by the electromagnetic force plunger coupled to an upper surface of the valve seat solenoid portion consisting provided with a; includes, on an upper surface of the valve seat to the engaging groove is an inner bottom surface made of a flat structure is formed concave, the lower has its bottom surface as concave coupling in the coupling groove of the valve seat of the plunger is a central the direct-acting solenoid valve is provided to increasingly characterized by forming an engaging projection formed of a round convex structure constituted by extension.
