제2도는 동측면도.
도면중 주요 부분에 대한 부호의 설명
400:부압스위치장치 401:압력센서(Sensor) 431:일방향변(辯) 436:변구(辯口) 441:링(Ring) 443:스프링 500:부압발생장치.
Claims (2)
- 부압공기의 유통로중에 압력센서를 장치한 부압스위치 장치에 있어서, 압력센서보다도 부압발생장치측의 유통로에 반 부압발생장치방향으로서의 공기유통을 저지하는 일방향변을 설치한 것을 특징으로하는 부압스위치 장치.
- 청구범위 제1항에 있어서, 일방향변을 상태(常態)에서는 부압발생장치측으로부터 산단의 V링구로서 변구(辯口)를 폐색하도록 스프링의 탄력으로 힘을주어 형성한 부압스위치장치.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
