Description

차량용 가변흡기 연동습식형 에어클리너{Air Cleaner in Vehicle}Variable air intake for vehicle Air cleaner {Air Cleaner in Vehicle}

본 발명은 차량용 에어클리너에 관한 것으로, 더욱 상세하기로는 흡입된 공기량의 다소에 관계없이 가변흡기 연동밸브를 이용하여 항상 청정한 공기만을 엔진으로 공급할 수 있도록 이루어진 차량용 가변흡기 연동습식형 에어클리너에 관한것이다.The present invention relates to a vehicle air cleaner, and more particularly, to a variable intake interlocking wet type air cleaner for a vehicle configured to supply only clean air to the engine at all times by using a variable intake peristaltic valve regardless of the amount of intake air. .

일반적으로 차량용 습식형 에어클리너는 에어클리너 본체 중앙에 형성된 에어 통로로 흡입된 공기를 케이스 내부 하부쪽에 내장된 오일면에 공기를 충돌시키어 이 공기와 함께 흡입된 먼지와 같은 각종 이물질을 제거하고 이중 일부공기와 오일혼합물은 엘리먼트를 통과하면서 오일은 엘리먼트에 의하여 하부로 자유낙하하고 여과된 깨끗한 공기만이 출구쪽으로 빠져 엔진에 공급되도록 되어 있다.In general, a wet type air cleaner for a vehicle collides air sucked into the air passage formed in the center of the air cleaner main body to the oil surface built into the lower part of the case to remove various foreign substances such as dust sucked with the air, and some of them As the air and oil mixture passes through the element, the oil falls freely downwards by the element and only the filtered, clean air is drawn out of the outlet and supplied to the engine.

그러나 종래 이와 같은 습식형 에어클리너는 흡입공기량이 적은 엔진 아이들 상태 내지는 저속시에 에어통로로 흡입된 공기의 일부가 케이스 내부바닥에 있는 오일면에 부딪히지 못하여 여과되지 않은채 엘리먼트를 통과하여 출구를 통해 엔진으로 공급됨에 따라 이물질을 내포한 공기는 엔진의 피스톤밸브와 실린더에 연마재로 작용하여 부품 마모를 촉진시키게 되는 단점을 지니고 있었다.However, in the conventional wet type air cleaner, a part of the air sucked into the air passage in the engine idle state or the low speed of the intake air amount does not come into contact with the oil surface on the bottom of the case and passes through the element without being filtered. As the engine was supplied to the engine, the air containing foreign substances acted as an abrasive to the piston valve and the cylinder of the engine, which had the disadvantage of promoting component wear.

종래에도 이러한 문제를 감안하여 도 2에 도시된 바와 같이 공기 흡입통로(101)쪽으로 흡입되는 공기가 적을때 오일(104)에 부딪히는 공기량을 증가시키기 위해 오리피스(112)를 설치하여 흡입공기량을 증가시키는 방식이 제안되었으나, 이는 공기량 증가시 통기저항의 증가로 인하여 엔진출력의 저하가 발생될 뿐만 아니라 빠른 공기 유동으로 인하여 오일과 먼지의 혼합물이 엘리먼트(105)에서 분리되지 못하고 케이스(103)의 출구(102)를 빠져나가 엔진의 연소실로 흡입되는 일명 오일캐리오버 현상이 발생되어 엔진수명에 치명적으로 작용하는 문제점이 있었다.In view of such a problem in the related art, as shown in FIG. 2, when the amount of air sucked toward the air intake passage 101 is small, an orifice 112 is installed to increase the amount of air collided with the oil 104. Although the method has been proposed, it is not only that the engine output is lowered due to the increase in airflow resistance when the amount of air is increased, but also that the mixture of oil and dust is not separated from the element 105 due to the rapid air flow and the outlet of the case 103 ( An oil carryover phenomenon, which is passed through 102) and sucked into the combustion chamber of the engine, occurs, causing a fatal effect on the engine life.

이에 본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 발명된 것으로, 흡입공기량의 증가시 통기저항 증가 와 오일 캐리오버 현상을 방지하고, 흡입공기량이 적을 때에는 공기의 흐름속도를 증가시키어 엔진으로 공급되는 공기를 항상 청정된 상태로 공급하는 차량용 가변흡기 연동습식형 에어클리너를 제공함에 그 목적이 있다.Therefore, the present invention has been invented to solve the conventional problems as described above, to prevent the increase of the ventilation resistance and oil carryover phenomenon when the intake air amount is increased, increase the flow rate of air when the intake air amount is low to supply to the engine It is an object of the present invention to provide a variable intake interlocking wet type air cleaner for a vehicle that always supplies clean air.

상기와 같은 목적을 달성하는 본 발명은 공기 흡입통로와 출구를 구비하고 케이스 내부 하부에 오일이 내장되면서 이 오일과 이격되어 엘리먼트를 갖춘 습식형 에어클리너에 있어서, 상기 공기흡입 통로의 내부에 가변흡기 연동밸브가 장착되되, 이 가변흡기 연동밸브는 고정봉에 설치된 스프링에 의하여 2개의 반원추형 밸브편들이 탄지되어 있으며, 상기 고정봉이 장착되는 공기흡입통로에는 밀봉을 위해 시일재가 장착되어 있다.The present invention to achieve the above object is a wet type air cleaner having an air intake passage and an outlet, and the oil is built in the lower portion of the inside of the case and spaced apart from the oil, the variable intake inside the air intake passage The peristaltic valve is mounted, and the variable intake peristaltic valve is supported by two semi-conical valve pieces by a spring installed in the fixed rod, and a sealing material is mounted in the air suction passage in which the fixed rod is mounted.

이하 본 발명을 첨부된 예시도면에 의하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 차량용 가변흡기 연동습식형 에어클리너를 나타낸 단면도로서, 도면에 도시된 바와 같이 본 발명은 공기흡입통로(1)와 출구(2)를 구비하고 케이스(3)내부 하부쪽에 오일(4)이 내장되면서 이 오일(4)과 이격되어 엘리먼트(5)를 갖춘 습식형 에어클리너에 있어서, 상기 공기 흡입통로(1)의 내부에 가변흡기연동밸브(6)가 장착되되, 이 가변흡기연동밸브(6)는 고정봉(7)에 설치된 스프링(8)에 의하여 2개의 반원추형 밸브편(9a,9b)들이 탄지되어 이루어진 구조로 되어 있다.1 is a cross-sectional view showing a variable intake vehicle interlocking wet type air cleaner according to the present invention, as shown in the drawing, the present invention includes an air intake passage 1 and an outlet 2, and a case 3 in the lower portion of the inner side. In the wet air cleaner having the element 5 spaced apart from the oil 4 while the oil 4 is built in, the variable intake interlocking valve 6 is mounted inside the air intake passage 1. The variable intake interlock valve 6 has a structure in which two semi-conical valve pieces 9a and 9b are supported by a spring 8 provided in the fixed rod 7.

그리고 상기 반원추형 밸브편(9a,9b)들의 꼭지점 부근은 개방되어 일정한 구멍(10)이 형성되어 있으며, 상기 고정봉(7)이 끼워 장착되는 공기 흡입통로(1)에는 시일재(11)가 장착되어 밀봉상태를 유지하도록 되어 있다.In addition, near the vertices of the semi-conical valve pieces 9a and 9b are opened to form a constant hole 10, the sealing material 11 is provided in the air intake passage 1 to which the fixing rod 7 is fitted. It is mounted to maintain a sealed state.

이어 본 발명의 작용을 살펴보면 다음과 같다.Looking at the operation of the present invention as follows.

상기 케이스(3)의 공기흡입통로(1)쪽으로 흡입 공기량이 적은 엔진아이들 상태나 저속시에는 가변흡기연동밸브(6)를 폐쇄하는 고정봉(7)의 스프링(8)의 설정 토오크에 의해 2개의 반원추형 밸브편(9a,9b)이 구멍(10)만 개방된채 닫혀 있는데, 이어 공기량이 증가하여 부압이 이 스프링(8)의 설정토오크를 넘게 되면 고정봉(7)을 회전축으로 하여 이 가변흡기연동밸브(6)는 서서히 열리면서 흡입단면적이 증가하게 된다.When the engine idle state with a small amount of intake air toward the air intake passage 1 of the case 3 or at a low speed is set, the torque is set by the spring 8 of the fixed rod 7 which closes the variable intake interlock valve 6. The two semi-conical valve pieces 9a and 9b are closed with only the hole 10 open. Then, when the air volume increases and the negative pressure exceeds the set torque of the spring 8, the fixed rod 7 is used as the rotating shaft. The variable intake linked valve 6 is gradually opened while increasing the suction cross-sectional area.

그리고 흡입공기량이 적어지면 다시 스프링(8)의 설정토오크에 의해 상기 가변흡기연동밸브(6)가 닫혀져 흡입단면적이 적어지는 반복적인 작동을 연속적으로 수행한다.When the amount of intake air decreases, the variable intake interlock valve 6 is closed again by the set torque of the spring 8 to continuously perform the repetitive operation of decreasing the suction cross-sectional area.

따라서 케이스(3)의 공기흡입통로(1)도 유입되는 공기의 양에 따라 공기속도를 적절하게 조절하여 흡입된 공기가 항상 오일과 부딪혀서 엘리먼트(5)를 거쳐 출구(2)쪽으로 공급되도록 되어 있다.Therefore, the air intake passage 1 of the case 3 is also adapted to adjust the air speed appropriately according to the amount of air introduced, so that the sucked air always collides with oil and is supplied to the outlet 2 via the element 5. .

본 발명은 종래 오리피스형 에어클리너의 약점인 흡입공기량 증가시 통기저항증가 및 오일캐리오버 문제를 가변흡기 연동밸브를 사용함으로써 해결하고, 또한 정지시나 저속시에는 밸브가 적게 열려 공기속도를 증가시켜 청정효율을 좋게하여엔진 운전 전구간에서 항상 깨끗한 공기를 연소실에 공급할 수 있도록 되어 있다.The present invention solves the problem of increased airflow resistance and oil carryover problem by using a variable intake interlock valve at the time of increasing the intake air volume, which is a weak point of the conventional orifice type air cleaner. By improving the efficiency, it is possible to supply clean air to the combustion chamber all the time between engine operation.
