Claims

[Claims for Utility Model Registration] (1) A sleeve in which a first port, a large-diameter guide hole communicating with the first port, a tapered part, a small-diameter seal hole, a female thread, and a second port are successively arranged. ,
A small diameter sliding guide portion at the tip, a communication path with the second port, a tapered seat contact portion, a large diameter insertion portion having an annular seal on the outer periphery that fits into the seal hole, and a male thread that fits into the female thread. and a guide poppet having one end fixed to the plug and in oil-tight sliding contact with the outer periphery of the sliding guide part, and the other end capable of contacting with the seat contact part to establish communication between the communication path and the first port. An electromagnet device including a hollow seat having a blocking seat portion, a movable iron core fixed to the sleeve and capable of driving the plug, and a spring biasing the plug in a direction away from the sliding guide portion. . A fluid control valve, wherein the internal and external threads are fixed in position by a fixing device after they are fitted. (2) The electromagnetic device includes a fixed iron core arranged so as to be able to come into contact with the plug, and a movable iron core that passes through an axial through hole provided in the fixed iron core and drives a rod that can come into contact with the plug. The fluid control valve according to item 1. (3) The electromagnet device includes a movable core disposed in contact with the plug so as to be drivable, and a fixed core disposed on the opposite side of the movable core so as to attract the movable core. Fluid control valve. (4) The fluid control valve according to claim 2 or 3, further comprising a second spring stronger than the spring that urges the movable core away from the fixed core.
