- 밀폐된 내부 공간을 형성하고 냉매가 유입되고 토출되는 흡입관 및 토출관이 형성된 케이싱과,상기 케이싱의 내측에 고정되며 토출구가 형성된 고정스크롤과,상기 고정스크롤과 상대 선회운동하며 연속적인 압축공간을 형성하여 냉매를 압축하는 선회스크롤과,상기 토출구를 통해 압축되어 토출된 냉매가 상기 토출관을 통해 외부로 공급된 후에 역류되는 것을 방지하도록 상기 토출관에 장착된 체크밸브 조립체가 구비되어 구성되는 것을 특징으로 하는 스크롤압축기의 역류방지장치.
- 제 1항에 있어서, 상기 고정스크롤의 상단면에는 상기 토출구와 연통되고 상기 케이싱의 내부와 별도의 내부공간으로 구획되는 토출실을 갖으며 상기 토출관에 연결되고 체크밸브 조립체가 장착되는 토출실커버가 포함되어 구성되는 것을 특징으로 하는 스크롤압축기의 역류방지장치.
- 제 1항 또는 제 2항에 있어서, 상기 체크밸브 조립체는 상기 토출관의 끝단부에 그 일측이 결합되고 그 내부에 토출관의 내경보다 확장된 내경을 갖는 관통공이 형성되고 그 관통공의 타측에는 상기 관통공보다 축소된 내경을 갖는 흡입구가 형성된 밸브하우징과, 상기 밸브 하우징의 관통공에 삽입되어 슬라이딩되며 냉매의 흐름을 제어하는 역지밸브로 구성되는 것을 특징으로 하는 스크롤 압축기의 역류방지장치.
- 제 3항에 있어서, 상기 밸브하우징이 관통공에는 상기 역지밸브가 상기 밸브하우징의 관통공과 일정간격을 유지하도록 소정의 높이로 돌출 되고 길이방향으로 연장된 가이드돌기가 구비되어 구성되는 것을 특징으로 하는 스크롤 압축기의 역류방지장치.
- 제 3항에 있어서, 상기 역지밸브는 상기 흡입구의 내경보다는 크고 밸브 하우징의 내경보다는 작은 지름을 갖는 판형의 개폐부와, 상기 개폐부가 상기 밸브하우징의 관통공과 일정간격을 유지하며 슬라이딩하도록 그 외주면에 소정의 높이로 돌출 되고 상기 토출관 방향으로 연장된 다수개의 가이드부가 구비되어 구성되는 것을 특징으로 하는 스크롤 압축기의 역류방지장치.
- 제 5항에 있어서, 상기 가이드부는 상기 개폐부의 중심점을 기준으로 120도의 간격을 유지하도록 형성되는 것을 특징으로 하는 스크롤 압축기의 역류방지장치.
