The present invention relates to a watertight chamber type electric vacuum pump and a vacuum boost brake system. The electric vacuum pump (1) applied to the vacuum boost brake system (100) of the present invention forms a water filling capacity that is greater than the water backflow capacity of an internal space of a pump housing (20) forming a vacuum pressure, and has a watertight chamber (10) connected to a discharge port (25) of the pump housing (20). Therefore, the cost and weight are reduced due to the elimination of the existing snorkeling hose device by securing watertightness for the electric vacuum pump (1) mounted in a poor watertight position. In particular, the possibility of water backflow caused by stopping the driving of a motor (30) is blocked by the water receiving capacity of the watertight chamber (10), thereby preventing damage to an internal electric circuit even under water immersion.

    본 발명의 진공 배력 브레이크 시스템(100)에 적용된 전동 진공펌프(1)는 진공 압력을 형성하는 펌프 하우징(20)이 갖는 내부공간의 물 역류 용량 보다 큰 물 충진 용량을 형성하고, 상기 펌프 하우징(20)의 배출 포트(25)에 연결된 수밀 챔버(10)를 구비함으로써 수밀 불량 위치에 장착된 전동 진공펌프(1)에 대한 수밀확보로 기존의 스노클링(Snorkling) 호스 장치 삭제에 따른 원가 및 중량 저감이 이루어지고, 특히 모터(30)의 구동 중지 발생되는 물 역류 가능성이 수밀 챔버(10)의 물 수용 용량으로 차단함으로써 수분 침수 상헝에서도 내부의 전기회로 손상을 방지하는 특징이 구현된다.
