PROBLEM TO BE SOLVED: To provide a downsized solenoid valve.SOLUTION: A solenoid valve 90 includes: a coil 10; a first valve seat 26 provided at an end portion on one side in an axial A direction; a fixed iron core 11 which has a communication path 23 communicating the first valve seat 26 and an outer peripheral surface, and is excited by the coil 10; an inside cylinder portion 12 provided at an end portion on one side of the fixed iron core 11; a moving iron core 14 which has a first valve body 28 forming an inside channel 32 between an inner peripheral surface of the inside cylinder portion 12 and the first valve body 28, capable of relatively moving to the inner peripheral surface in the axial direction A, and provided at an end portion on the other side in the axial direction A so as to abut on and separate from the first valve seat 26, and a second valve body 29; an outside cylinder 13 which forms an outside channel 33 communicating to the communication path 23; and a valve body 15 which has a valve chamber V1 communicating to the inside channel 32, a second valve seat 27 on which and from which the second valve body 29 abuts and separates, a first port P1 communicating the second valve seat 27 and an outer surface, a second port P2 communicating the inside of the valve chamber V1 and the outer surface, and a third port P3 communicating the outside channel 33 and the outer surface.SELECTED DRAWING: Figure 2

    【課題】小型化された電磁弁を提供する。【解決手段】電磁弁90は、コイル10と、軸線A方向一方側の端部に設けられた第一弁座26、第一弁座26と外周面とを連通する連通路23を有し、コイル10によって励磁される固定鉄芯11と、固定鉄芯11の一方側の端部に設けられる内側筒部12と、内側筒部12の内周面との間に内側流路32を形成し、内周面に対して軸線A方向に相対移動可能であり、軸線A方向他方側の端部に設けられて第一弁座26に当接離間する第一弁体28と、第二弁体29とを有する可動鉄芯14と、連通路23に連通する外側流路33を形成する外側筒部13と、内側流路32に連通する弁室V1、第二弁体29が当接離間する第二弁座27、第二弁座27と外面とを連通する第一ポートP1、弁室V1内と外面とを連通する第二ポートP2、及び、外側流路33と外面とを連通する第三ポートP3を有する弁本体15とを備える。【選択図】図2
