The present invention relates to a damper for a railway vehicle having a body valve with a relief valve. The damper for a railway vehicle having a body valve with a relief valve comprises: a first relief valve to which the end of an inner tube is fixed and which allows working fluid to flow in a seal stroke in a body valve mounted in a base cap coupled to a base shell; and a second relief valve which allows the working fluid to flow in a compression stroke. Therefore, the present invention maintains the durability of a vehicle body and improves riding comfort by satisfying the damping force properties required for a railway vehicle from a structure where flexible parts are formed in the first and second relief valves, respectively.

    본 발명은 이너 튜브의 단부가 고정되고 베이스 쉘과 결합된 베이스 캡에 안착되는 바디 밸브에 인장 행정시 작동 유체의 흐름을 허용하는 제1 릴리프 밸브와 압축 행정시 작동 유체의 흐름을 허용하는 제2 릴리프 밸브를 구비하되, 제1 릴리프 밸브와 제2 릴리프 밸브에 각각 가변부를 구비한 구조로부터 철도 차량에서 요구되는 감쇠력 특성을 만족시켜 차체의 내구성을 유지하고 승차감을 향상시킬 수 있도록 한 릴리프 밸브를 포함한 바디 밸브를 가지는 철도 차량용 댐퍼에 관한 것이다.
