본 발명은 철도차량용 왕복동식 연속 환기장치에 관한 것으로서, 좀더 상세하게는 열차의 철도차량에 설치되어 외부 공기를 유입하면서도 실내 압력의 변동을 방지함으로써 승객 이명감을 저감하고, 쾌적성을 향상시킬 수 있도록 하는 철도차량용 왕복동식 연속 환기장치에 관한 것이다.본 발명은 구동부와, 상기 구동부에 의해 작동하는 제1 및 제2피스톤부를 ㅍ포함하여 이루어지되, 상기 제1피스톤부의 작동 시 개폐되어 각각 실내 공기 또는 외부 공기를 순차적으로 흡기하는 제1 및 제2밸브부와, 상기 제2피스톤부의 작동 시 개폐되어 각각 실내 공기 또는 외부 공기를 순차적으로 배기하는 제3 및 제4밸브부가 더 구비되는 것을 특징으로 한다.
The present invention relates to a reciprocating-type continuous ventilation apparatus for a railway vehicle and, more specifically, to a reciprocating-type continuous ventilation apparatus for a railway vehicle, which is installed in a railway vehicle of a train to prevent indoor pressure variation while introducing outdoor air, thereby reducing the sense of tinnitus for passengers and creating a pleasant environment. The present invention comprises a driving part and first and second piston parts operated by the driving part, and further comprises first and second valve parts opened and closed in the operation of the first piston part so that each thereof can sequentially suck indoor or outdoor air and third and fourth valve parts opened and closed in the operation of the second piston part so that each thereof can sequentially exhaust the indoor or outdoor air.
