PROBLEM TO BE SOLVED: To provide a solenoid valve which performs suppression of self-excited vibration with a simple structure, and which has improved alignment accuracy/controllability.SOLUTION: A solenoid valve is formed by: a plunger sucked and driven by an excited coil; a valve body disposed in series in the axial direction with the plunger and in a radially movable manner; a seat part having a valve seat which the valve body comes into contact with/is separated from; an inflow hole located on the upstream side of the valve seat; a valve chamber which is provided on the downstream side of the valve seat and in which the valve body and the valve seat are arranged; an outflow hole located on the downstream side of the valve chamber; a guide part for partitioning a first space in which the valve chamber and the valve seat are disposed and a second space in which the plunger is disposed, and for restricting the movement of the valve body in the radial direction; and a through-hole for communicating the first space and the second space.SELECTED DRAWING: Figure 2

    【課題】簡易な構成にて自励振動の抑制を行なうとともに、調心精度/制御性を向上させた電磁弁を提供することを目的とする。【解決手段】電磁弁は、励磁されたコイルによって吸引駆動されるプランジャと、プランジャと軸方向直列かつ径方向移動可能に配設される弁体と、弁体が接離する弁座を有するシート部と、弁座の上流側に位置する流入孔と、弁座の下流側に設けられて内部に弁体および弁座が配置される弁室と、弁室の下流側に位置する流出孔と、弁室を弁座が配設される第1の空間と、プランジャが配設される第2の空間とを区画し、弁体の径方向移動を規制するガイド部と、第1の空間と、第2の空間とを連通する貫通孔とによって形成される。【選択図】図2
