제1도는 본 발명에 따른 진공체임버가 내장된 서지탱크의 부분절단 설명도이고, 제2도는 제1도의 A-A선을 기준으로 서지탱크와 진공체임버의 연결밸브의 개략적인 단면 설명도인 바, 본 발명은 서지탱크(1)의 내부에 위치한 진공체임버(2)와, 상기 진공체임버(2)의 상면에 위치하여 상기 서지탱크(1)에서 진공상태로 유도하는 진공흡입구(3)와, 상기 진공체임버(2)의 내부공간에 위치하면서 서지탱크(1)에서 진공체임버(2)로 공기의 역류를 방지하도록 상기 진공흡입구(3)에 연결되어지는 한편 체크밸브(10)를 내장하고 있는 체크밸브바디(4)와, 상기 진공체임버(2)와 상기 서지탱크(1)를 분리/밀봉하는 매개체인 스틸재질의 가스켓(5)과, 상기 서지탱크(1)내에 내설되어지는 가변흡기밸브(6)과, 상기 진공체임버(2)로부터 다이아프램 액튜에이터(7)에 연결되는 진공인출구(8)로 이루어진다.1 is a partial cutaway explanatory diagram of a surge tank incorporating a vacuum chamber according to the present invention, and FIG. 2 is a schematic cross-sectional explanatory diagram of connection valves of a surge tank and a vacuum chamber based on the AA line of FIG. According to the present invention, a vacuum chamber (2) located inside the surge tank (1), a vacuum suction port (3) located on the upper surface of the vacuum chamber (2) and guided to a vacuum state in the surge tank (1), and the vacuum A check valve which is located in the inner space of the chamber 2 and connected to the vacuum inlet 3 to prevent backflow of air from the surge tank 1 to the vacuum chamber 2 and has a check valve 10 incorporated therein. A body 4, a gasket 5 made of steel, which is a medium for separating / sealing the vacuum chamber 2 and the surge tank 1, and a variable intake valve 6 housed in the surge tank 1 ) And a vacuum connected from the vacuum chamber 2 to the diaphragm actuator 7 It consists of an outlet 8.
따라서 상기 진공체임버(2)가 서지탱크(1)의 내부에 설치되어지므로, 종래기술에서 나타난 바와 같은 별도의 진공체임버(2)가 점유되어지는 공간부피(제3도참조)를 반드시 필요로 하게 되는 문제점을 해소 할 수 있고 이로 인하여 엔진본체의 전체적인 부피를 감소시키며, 차량구조를 컴팩트(compact)화 할 수 있으면서도 상기 체크밸브(10) 역시 서지탱크(1)내의 진공체임버(2)에 위치하게 되므로 이에 대한 공간도 감소시킬 수 있다.Therefore, since the vacuum chamber 2 is installed inside the surge tank 1, it is necessary to necessarily require a space volume (see FIG. 3) in which a separate vacuum chamber 2 as shown in the prior art is occupied. It is possible to solve the problem, thereby reducing the overall volume of the engine body, while compacting the vehicle structure (compact) while the check valve 10 is also located in the vacuum chamber (2) in the surge tank (1) Therefore, the space for this can be reduced.
이상 설명한바와 같이 본 발명에 의하면, 서지탱크(1)내에 진공체임버(2)를 구비하도록 구성함에 따라, 종래 진공체임버(2)가 차지하는 별도의 공간이 폐지되어 엔진의 공간활용도를 향상함은 물론 각종 지지 브라켓이나 볼트등도 줄일 수 있고, 엔진자체를 컴팩트화 할 수 있다.As described above, according to the present invention, as the vacuum chamber 2 is provided in the surge tank 1, the separate space occupied by the conventional vacuum chamber 2 is abolished, and of course, the space utilization of the engine is improved.
