SAFETY VALVE

The invention relates to a safety valve which pressurizes an elastic component in a housing based an oil pressure for regulating a release pressure. The safety valve comprises the components of a plunger which is elastically supported by the elastic component and is internally provided with a main plunger flow path in a manner that oil that flows into the housing can move; an adjusting stopper which is hollow at the inner part and is arranged at one side of the housing; and a piston which is configured in a manner that the inner circumferential surface faces the outer circumferential surface of one area of the plunger. One area of the outer circumferential surface divides the inner part of the adjusting stopper into a first chamber and a second chamber, and moves through the oil pressure or the elastic component. 本发明涉及一种安全阀，其在壳体内部基于油的压力对弹性部件加压来调节释放压力，所述安全阀包括：柱塞，其被所述弹性部件弹性支撑，且以向所述壳体的内部流入的油能够移动的方式在内部形成有主柱塞流路；调节塞，其内部为中空形，且设置于所述壳体的一侧；以及活塞，其配置为内周面与所述柱塞的一区域的外周面相向，外周面的一区域将所述调节塞的内部划分为第一腔室和第二腔室，且通过油的压力或所述弹性部件移动。
