자동차용 오일펌프Automotive oil pump

본 고안은 자동차 윤활계통의 오일펌프에 관한 것으로서, 특히 오일펌프의 오일배출구에 기포수집부를 형성하여, 엔진으로 공급되는 오일의 기포함유량을 현저히 격감시킬 수 있게 한 자동차용 오일펌프에 관한 것이다.The present invention relates to an oil pump of an automotive lubrication system, and more particularly, to an automobile oil pump that forms a bubble collecting portion at an oil outlet of an oil pump, thereby significantly reducing the air-containing flow rate of oil supplied to an engine.

일반적으로 자동차 윤활계통의 오일펌프는 첨부도면 제2도에 도시한 바와 같이 오일스크린(11)으로 통하는 오일흡입구(12)와, 압송부(13)를 거쳐 오일필터(14)로 통하는 오일배출구(15)를 포함하고 있다.Generally, the oil pump of the automotive lubrication system has an oil inlet 12 connected to the oil screen 11 and an oil outlet 14 through the pressure feeder 13 as shown in FIG. 15) is included.

그러나, 이와 같은 기존의 욀펌프에서는 오일속에 함유되어 있는 기포를 효과적으로 제거할 수 있는 수단이 마련되어 있지 않아 기포를 함유한 오일이 그대로 공급되어 윤활성을 해치게 되는 문제점을 안고 있었다.However, such a conventional shock pump does not have a means for effectively removing the bubbles contained in the oil has had a problem that the oil containing the bubble is supplied as it is to impair the lubricity.

따라서, 본 고안은 이와 같은 점을 감안하여 안출한 것으로서, 오일펌프의 압송부와 배출부 사이에 기포수집부를 형성하여 오일펌프에서 배출되는 오일의 기포함유량을 현저히 줄일 수 있게 함으로써, 엔진오일의 윤활성능을 기대할 수 있게 한 자동차용 오일펌프를 제공하는데 그 목적이 있는 것이다.Therefore, the present invention has been devised in view of such a point, and by forming a bubble collecting portion between the pump portion and the discharge portion of the oil pump, it is possible to significantly reduce the air-containing flow rate of the oil discharged from the oil pump, thereby lubricating the engine oil The aim is to provide automotive oil pumps that enable performance to be expected.

본 고안은 자동차용 오일펌프(14)에 있어서, 상기 오일필터(14)의 압송부(13)와 오일배출구(15) 사이에는 소정의 체적을 갖는 기포수집부(16)가 형성되고, 상기 기포수집부(16)의 바닥면에는 압송부(13)와 통하는 입구 바로 뒷쪽에 오일의 흐름을 윗쪽으로 유도할 수 있는 돌출부(19)가 형성되고, 수포수집부(16)의 중심부에는 기포유도관(17)이 직립 설치되며, 상기 기포유도관(17)은 펌프의 외곽셸 바닥두께를 관통하면서 그 저부의 릴리프밸브(18)와 연통 연통되는 것을 특징으로 한다.In the present invention, in the automotive oil pump 14, a bubble collecting portion 16 having a predetermined volume is formed between the pressure feeding portion 13 and the oil discharge port 15 of the oil filter 14, the bubble At the bottom of the collecting portion 16, a projection 19 is formed at the rear of the inlet communicating with the pressure feeding portion 13 to induce the flow of oil upward, and at the center of the blister collecting portion 16, a bubble induction pipe is formed. (17) is installed upright, the bubble guide pipe 17 is characterized in that in communication with the bottom of the relief valve 18 of the bottom while passing through the outer shell bottom thickness of the pump.

특히, 상기 기포유도관(17)의 상단부는 돌출부(19)에 의해 기포수집부(16)의 천정부에 모여진 기포들이 기포유도관(17)의 상단 입구를 통하여 릴리프밸브(18)로 보내질 수 있도록 기포수집부(16)의 천정부에 근접되도록 설치되는 것을 특징으로 한다.In particular, the upper end of the bubble induction pipe 17 so that bubbles collected at the ceiling of the bubble collecting part 16 by the protrusion 19 can be sent to the relief valve 18 through the upper inlet of the bubble induction pipe 17. Characterized in that installed near the ceiling of the bubble collecting unit (16).

이를 좀 더 상세히 설명하면 다음과 같다.This will be described in more detail as follows.

첨부도면 제1도는 본 고안의 오일펌프를 나타내는 단면도이다.1 is a cross-sectional view showing an oil pump of the present invention.

여기서, 도면부호 11은 오일팬 내부에 위치되는 오일스크린이고, 12는 상기 오일스크린(11)으로부터 연통되는 오일흡입구를 나타낸다.Here, reference numeral 11 denotes an oil screen positioned inside the oil pan, and 12 denotes an oil suction port communicating from the oil screen 11.

오일팬 내부의 오일이 상기 오일흡입구(12)를 통하여 펌프내부, 즉 압송부(13)로 강제 흡입되고, 상기 압송부(13)의 로터운동에 따라 이때 흡입된 오일이 오일배출구(15)를 통하여 펌프측의 오일필터(14)로 보내질 수 있게 된다.The oil inside the oil pan is forced into the pump through the oil suction port 12, that is, the pressure feeding part 13, and the oil sucked at this time according to the rotor movement of the pressure feeding part 13 opens the oil discharge hole 15. It can be sent to the oil filter 14 on the pump side.

특히, 도면부호 16은 기포수집부를 나타낸다.In particular, reference numeral 16 denotes a bubble collecting portion.

상기 기포수집부(16)는 압송부(13)와 오일배출구(15)의 직선구간의 소정의 위치에서 윗쪽으로 일정체적 확장 성형되는 공간부를 의미한다.The bubble collecting portion 16 refers to a space portion which is formed to be expanded in a constant volume upward at a predetermined position of a straight section of the pressure feeding portion 13 and the oil discharge port 15.

따라서, 압송부(13)에서 오일배출구(15)로 보내지는 오일은 기포수집부(16)내에 일시 저장되었다가 오일배출구(15)로 보내질 수 있게 된다.Therefore, the oil sent from the pumping unit 13 to the oil outlet 15 may be temporarily stored in the bubble collecting unit 16 and then sent to the oil outlet 15.

이때, 상기 기포수집부(16) 내에 일시 저장되는 오일은 그 속에 함유되어 있는 기포가 윗쪽으로 상승될 수 있게 되고, 이렇게 상승되어 있는 기포들은 후술하는 기포유도관(17)에 의해 오일펌프의 내압을 제어하는 릴리프밸브(18)로 보내질 수 있게 된다.At this time, the oil temporarily stored in the bubble collecting unit 16 is the bubbles contained therein can be raised upward, the bubbles are raised so that the internal pressure of the oil pump by the bubble induction pipe 17 to be described later It can be sent to the relief valve 18 to control.

이를 위하여 상기 기포수집부(16)의 체적 중심부에는 기포유도관(17)이 직립 설치되고, 이때의 기포유도관(17)은 펌프의 외곽셸 바닥두께를 관통하면서 그 저부의 릴리프밸브(18)와 연통되게 된다.To this end, the bubble induction pipe 17 is installed upright in the volume center of the bubble collecting unit 16, the bubble induction pipe 17 at this time passes through the outer shell bottom thickness of the pump while the relief valve 18 at the bottom thereof Will be communicated with.

이렇게 상기 기포유도관(17)을 통하여 릴리프밸브(18)에 유도된 기포는 오일팬으로 회수되어질 수 있게 된다.Thus, the bubbles guided to the relief valve 18 through the bubble guide pipe 17 can be recovered to the oil pan.

또한, 상기 기포수집부(16)의 바닥면에는 압송부(13)와 통하는 입구 바로 뒷쪽에 오일의 흐름을 윗쪽으로 유도할 수 있는 돌출부(19)가 형성되어 있다.In addition, the bottom surface of the bubble collecting portion 16 is formed with a protrusion 19 that can direct the flow of oil upwards just behind the inlet communicating with the pressure feeding portion 13.

이에 따라, 압송부(13)에서 기포수집부(16)로 유입되는 오일은 뒷쪽으로 상승흐름을 탈 수 있게되고, 이와 함께 오일내에 함유된 기포도 윗쪽으로 상승되어 기포수집부(16)의 천정부 근방에 모여질 수 있게되며, 이렇게 특정부위에 모여진 기포들은 그곳에 위치되는 기포유도관(17)의 상단 입구를 통하여 릴리프밸브(18)로 보내질 수 있게된다.Accordingly, the oil flowing into the bubble collecting unit 16 from the pumping unit 13 is able to ride the upward flow to the rear, and together with the bubble contained in the oil is also raised upward, the ceiling of the bubble collecting unit 16 It can be collected in the vicinity, and the bubbles collected at a specific portion can be sent to the relief valve 18 through the upper inlet of the bubble guide pipe 17 located there.

이상에서와 같이 본 고안은 오일펌프의 내부에 효과적으로 기포를 수집할 수있는 기포수집부를 형성하고, 이곳을 이용하여 오일속에 함유된 기포를 대부분 수집 가능하게 함으로써, 오일이 갖는 윤활기능을 한층 향상시킬 수 있는 장점이 있는 것이다.As described above, the present invention forms an air bubble collecting part that can effectively collect air bubbles in the oil pump, and by using the air bubbles in the oil can be collected, thereby improving the lubrication function of the oil. There is an advantage that can be.
