Description

자동차용 엔진의 오일 스트레이너Oil Strainers For Automotive Engines

본 발명은 자동차용 엔진에 관한 것이며, 보다 구체적으로는 오일 팬에 저장된 오일을 오일 펌프로 안내하는 오일 스트레이너에 관한 것이다.The present invention relates to an engine for an automobile, and more particularly to an oil strainer for guiding oil stored in an oil pan to an oil pump.

널리 알려진 바와 같이, 자동차의 엔진은 구동 중 많은 부품들이 서로 마찰된다. 이러한 부품들은 대부분 상당히 큰 하중을 받으면서 고속으로 마찰되는 경우가 많다. 이와 같이 부품들을 마찰시키는 힘은 실린더의 팽창 행정에서 얻어지는 엔진의 동력에 대하여 손실을 유발하는 힘이고, 또한 그 부품을 마모시켜 수명을 단축시키며, 엔진의 전체적인 성능을 저하시키는 원인이 된다.As is well known, the engine of a motor vehicle has many parts rubbed against each other during driving. Most of these parts are often rubbed at high speeds under considerable load. Thus, the frictional force of the parts is a force that causes a loss to the power of the engine obtained in the expansion stroke of the cylinder, and also wears the parts to shorten the life and cause the overall performance of the engine.

이를 방지하기 위해 엔진에는 윤활 장치가 설치되어 있으며, 이러한 윤활 장치는 오일을 저장하는 용기인 오일 팬과, 오일 팬에 저장된 오일을 기관의 각 운동 부분으로 압송하는 오일 펌프와, 오일 팬으로부터 오일 펌프로 오일을 유도하는 오일 스트레이너 및 오일 펌프에서 압송된 오일의 압력을 일정한 압력으로 조정하는 밸브장치인 유압 조절기로 구성되어 있다.To prevent this, the engine is equipped with a lubrication device, which includes an oil pan, which is a container for storing oil, an oil pump that pumps the oil stored in the oil pan into each moving part of the engine, and an oil pump from the oil pan. It consists of an oil strainer that induces oil into the oil and a hydraulic regulator that is a valve device that adjusts the pressure of oil pumped from the oil pump to a constant pressure.

그 중에서 오일 팬에 저장된 오일을 오일 스트레이너로 안내하는 오일 스트레이너는 도 1 및 도 2에 도시된 바와 같이, 오일 팬(1)의 일측에 형성되어 있다.Among them, an oil strainer for guiding oil stored in the oil pan to the oil strainer is formed at one side of the oil pan 1, as shown in FIGS. 1 and 2.

즉, 오일 스트레이너(3)는 오일 팬(1)의 바닥면으로부터 일측벽을 타고 실린더 블록(2)의 일측에 설치된 오일 펌프(미도시)로 이어지는 장홀이며, 그 입구는 오일 팬(1)의 바닥면으로부터 상방을 향해 개구되어 있다. 그리고, 입자가 큰 이물질이 오일 스트레이너(3)를 통해 오일 펌프로 침투하는 것을 방지하기 위한 철망 (4)이 오일 스트레이너(3)의 입구에 설치되어 있다. 이러한 오일 스트레이너(3)는 오일 팬(1)의 내부 공간에 저장된 오일을 오일 펌프로 유도하고 또 불순물을 제거하는 역할을 한다.That is, the oil strainer 3 is a long hole leading from the bottom surface of the oil pan 1 to an oil pump (not shown) installed on one side of the cylinder block 2 by the one side wall, and the inlet of the oil pan 1 It is open upward from the bottom surface. In addition, a wire mesh 4 is installed at the inlet of the oil strainer 3 to prevent foreign particles having a large particle from penetrating into the oil pump through the oil strainer 3. The oil strainer 3 serves to guide oil stored in the internal space of the oil pan 1 to the oil pump and to remove impurities.

그러나, 상기와 같은 종래의 오일 스트레이너는 그 입구가 상방을 향하고 있기 때문에, 오일 펌프의 작동에 의해 오일 팬의 오일이 오일 스트레이너로 흡입될 때 기포가 발생되어 오일의 흡입성이 불량하고 소음이 발생될 우려가 높은 문제점이 있다.However, since the inlet of the conventional oil strainer as described above is upward, bubbles are generated when the oil in the oil pan is sucked into the oil strainer by the operation of the oil pump, resulting in poor oil intake and noise. There is a high problem of concern.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 오일 팬으로 부터 오일이 흡입될 때 기포가 발생되는 것을 방지할 수 있는 자동차용 엔진의 오일 스트레이너를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, an object of the present invention is to provide an oil strainer for an automotive engine that can prevent bubbles from occurring when oil is sucked from the oil pan.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 일 실시예를 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

본 실시예를 설명함에 있어서, 종래와 동일한 구성에 대해서는 동일한 참조부호를 부여하며, 중복되는 설명은 생략하고 개선된 부분을 위주로 설명한다.In the description of the present embodiment, the same reference numerals are given to the same components as in the related art, and redundant descriptions are omitted and the description will be given based on the improved parts.

본 발명의 일 실시예에 따른 자동차용 엔진의 오일 스트레이너가 도 3 및 도 4에 도시되어 있다.An oil strainer of an automotive engine according to one embodiment of the invention is shown in FIGS. 3 and 4.

도시된 바와 같이, 본 발명의 일 실시예에 따른 오일 스트레이너(3)는 장홀부(3)와 흡입 파이프(3a)를 포함하고 있다. 그리고, 오일 팬(1)은 그 바닥면 중앙부가 오목하게 형성되어 있다.As shown, the oil strainer 3 according to the embodiment of the present invention includes a long hole 3 and a suction pipe 3a. And the oil pan 1 is formed in the recessed bottom center part.

장홀부(3)는 오일 팬(1)의 일측벽 상면으로부터 오일팬(1)의 일측벽 내부를 따라 오목부의 상측까지 대략 'ㄴ' 형상으로 형성되어 있다. 장홀부의 상단은 실린더 블록(2)의 일측에 설치된 오일 펌프(미도시)와 소통된다.The long hole 3 is formed in a substantially 'b' shape from the upper surface of one side wall of the oil pan 1 to the upper side of the concave portion along the inside of one side wall of the oil pan 1. The upper end of the long hole is in communication with an oil pump (not shown) installed on one side of the cylinder block (2).

흡입 파이프(3a)는 대략 'ㄱ'형상을 가지며, 그 상단은 장홀부(3)에 압입되고, 그 하단은 하방을 향하도록 위치된다. 또한, 입자가 큰 이물질이 흡입 파이프 (3a)와 장홀부(3)를 통해 오일 펌프로 침투하는 것을 방지하기 위한 철망(4)이 흡입 파이프(3a)의 하단에 설치된다.The suction pipe 3a has an approximately 'a' shape, the upper end of which is pressed into the long hole 3, and the lower end thereof is positioned downward. In addition, a wire mesh 4 is installed at the lower end of the suction pipe 3a to prevent foreign particles having large particles from penetrating into the oil pump through the suction pipe 3a and the long hole 3.

오일 팬(1)의 오목부에 저장된 오일은 철망(4)이 설치된 흡입 파이프(3a)의 하단을 통해 흡입 파이프(3a)로 흡입된 다음 장홀부(3)를 따라 오일 펌프로 안내된다.The oil stored in the recess of the oil pan 1 is sucked into the suction pipe 3a through the lower end of the suction pipe 3a on which the wire mesh 4 is installed and then guided to the oil pump along the long hole 3.

상기된 바와 같은 본 발명은, 오일 스트레이너의 주입구가 하방을 향하므로 기포의 발생이 억제되어 오일의 흡입성이 크게 향상되고 소음이 저감되는 동시에 엔진의 성능이 향상되는 장점이 있다.According to the present invention as described above, since the inlet of the oil strainer is directed downward, the generation of bubbles is suppressed, so that the oil intake is greatly improved, the noise is reduced, and the performance of the engine is improved.
