본 고안은 이물질 유출방지 구조를 갖는 오일펌프에 관한 것으로서, 특히 오일펌프의 토출측에 스트레이너를 설치하여 이물질이 유출되는 것이 방지되는 이물질 유출방지 구조를 갖는 오일펌프에 관한 것이다.The present invention relates to an oil pump having a foreign substance leakage preventing structure, and more particularly, to an oil pump having a foreign substance leakage preventing structure that prevents foreign substances from leaking by installing a strainer on the discharge side of the oil pump.

자동차는 운전자가 차량의 운동을 제어할 수 있도록 조향장치가 설치되어 있는데, 현재에는 조향장치를 운전자가 손쉽게 제어할 수 있도록 조력하는 파워스티어링 장치가 일반화되어 설치되어 있다. 이 장치는 오일을 압축하여 그 압축된 오일을 사용하여 조향장치를 사용하게 된다.The vehicle is equipped with a steering device for the driver to control the movement of the vehicle, and now a power steering device for assisting the driver to easily control the steering device is installed in general. The unit compresses the oil and uses the compressed oil to use the steering system.

오일을 압축하는 파워스티어링 펌프로서는 베인펌프가 널리 사용되는데, 베인 펌프는 회전자에 일정 각 마다 방사형으로 외면이 개방된 다수개의 슬롯이 형성되고 그 각각의 슬롯에 베인이 설치되고, 그 회전자가 캠 링과 같이 내부가 원형과 타원형으로 형성된 부재 내부에서 회전동력을 전달받아 회전됨으로써 회전자의 베인이 원심력에 의해 원형과 타원형의 캠 링 내부에 접하면서 회전되어 인접하는 베인 사이의 부피 변화에 의해 오일이 압축되는 원리를 이용한다.As a power steering pump for compressing oil, a vane pump is widely used. A vane pump has a plurality of slots in which the outer surface is radially opened at a predetermined angle in the rotor, and vanes are installed in each of the slots. The rotor vane is rotated while contacting the inside of the circular and elliptical cam rings by centrifugal force, and the oil is changed by the volume change between adjacent vanes. This principle uses compression.

파워스티어링 오일은 오일펌프로 흡입 파이프를 통하여 유입된 다음 압축되어 기어박스쪽으로 보내진다.The power steering oil enters the suction pump through the oil pump and is then compressed and sent to the gearbox.

그러나, 종래의 오일펌프는 이물질이 오일펌프에 유입된 다음 기어 박스로 유입되어 작동불능 및 핸들 무거움의 원인이 되는 문제점이 있다.However, the conventional oil pump has a problem that foreign matters are introduced into the oil pump and then into the gearbox causing inoperability and handle weight.

본 고안은 상기한 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 토출측 커넥터에 스트레이너를 설치하여 기어박스로 유입될 수 있는 이물질을 미연에 차단하는 이물질 유출방지 구조를 갖는 오일펌프를 제공하는데 그 목적이 있다.The present invention has been made in order to solve the above problems of the prior art, by providing a strainer in the discharge-side connector to provide an oil pump having a foreign material leakage prevention structure to block the foreign matter that can be introduced into the gear box in advance. There is this.

본 고안에 의한 이물질 유출방지 구조를 갖는 오일펌프는 파워스티어링 오일이 유입된 다음 압축된 후 토출되는 구조를 갖는 오일펌프에 있어서, 상기 오일핌프의 오일이 토출되는 토출측에는 이물질이 걸러지는 스트레이너가 설치된 것을 특징으로 한다.Oil pump having a foreign material leakage prevention structure according to the present invention is an oil pump having a structure in which the power steering oil is introduced and then compressed and discharged, the strainer for filtering foreign matter is installed on the discharge side of the oil pump is discharged It is characterized by.

여기서, 상기 오일펌프의 토출측에는 커넥터가 조립되고, 커넥터의 중앙에는 원통형 통로가 형성되되, 상기 통로의 직경은 입구측으로부터 일정거리까지 증가된 다음 출구 끝까지 일정한 직경을 유지하도록 형성되고 직경이 일정하게 유지되기 시작한 곳에 상기 스트레이너가 설치되며 상기 스트레이너가 빠지지 않도록 단턱이 형성된 것을 특징으로 한다.Here, a connector is assembled at the discharge side of the oil pump, and a cylindrical passage is formed at the center of the connector. The diameter of the passage is increased to a certain distance from the inlet side and is formed to maintain a constant diameter until the end of the outlet and the diameter is constant. Wherein the strainer is installed in the starting position is characterized in that the step is formed so that the strainer does not fall out.

또, 상기 스트레이너는 링 형상의 지지대와 상기 지지대 사이에 끼워진 금속망으로 이루어진 것을 특징으로 한다.In addition, the strainer is characterized by consisting of a metal mesh sandwiched between the ring-shaped support and the support.

이하, 본 고안의 실시 예를 참조된 도면을 참조하여 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

우선 참조된 도면, 도 1은 본 고안에 의한 오일펌프의 투상 정면도, 도 2는 본 고안에 의한 오일펌프의 일부구성요소인 스트레이너의 정면도, 측면도, 그리고 측면도의 부분 확대도면, 도 3은 본 고안에 의한 오일펌프의 일부구성요소인 커넥 터의 단면도이다.1 is a perspective front view of an oil pump according to the present invention, FIG. 2 is a front view, a side view, and a partially enlarged view of a strainer which is a part of an oil pump according to the present invention, and FIG. Sectional drawing of the connector which is a part of the oil pump according to the present invention.

본 고안에 의한 이물질 유출방지 구조를 갖는 오일펌프(1)는 도 1 내지 도 3에 도시된 바와 같이 오일펌프(1) 본체의 일측에는 파워스티어링 오일이 유입되는 흡입 파이프(2)가 설치되어 있고, 다른 일측에는 압축된 오일이 토출되는 토출구가 형성되어 있으며, 토출구쪽에 커넥터(3)가 오일펌프(1) 본체에 조립되어 있다.Oil pump (1) having a foreign material leakage prevention structure according to the present invention is installed on one side of the main body of the oil pump (1) as shown in Fig. On the other side, a discharge port through which the compressed oil is discharged is formed, and the connector 3 is assembled to the oil pump 1 main body at the discharge port.

상기 커넥터(3)는 그 중앙에 원통형 통로(3a)가 형성되되, 상기 통로(3a)의 직경은 입구측으로부터 일정거리까지 증가된 다음 출구 끝까지 일정한 직경을 유지하도록 형성되고 직경이 일정하게 유지되기 시작한 곳에 스트레이너(5)가 설치되며 상기 스트레이너(5)가 빠지지 않도록 단턱(3b)이 형성되어 있다. 토출되는 오일은 상대부품인 아이볼트(4)와 고압호스(7)를 통하여 외부로 토출된다.The connector 3 has a cylindrical passage 3a formed at the center thereof, the diameter of the passage 3a is increased to a certain distance from the inlet side and is formed to maintain a constant diameter until the end of the outlet and the diameter is kept constant. The strainer 5 is installed at the beginning and the step 3b is formed so that the strainer 5 does not fall out. The discharged oil is discharged to the outside through the eye bolt 4 and the high pressure hose 7 which are counterparts.

도 2를 참고하면, 스트레이너(5)는 고리 형상의 지지대(5a)와 그 사이에 끼워진 금속망(5b)으로 이루어진다.Referring to FIG. 2, the strainer 5 consists of an annular support 5a and a metal mesh 5b sandwiched therebetween.

도 3을 참고하면, 스트레이너(5)는 커넥터(3)의 통로(3a) 직경이 일정하게 유지하기 시작하는 곳에 설치되되, 단턱(3b)에 걸려 빠지지 않도록 되어 있다. 물론 단턱(3b)은 오일의 흐름에 대하여 스트레이너(5)를 지지하도록 스트레이너(5) 후방에 형성되어 있다.Referring to FIG. 3, the strainer 5 is installed where the diameter of the passage 3a of the connector 3 starts to remain constant, but is not caught by the step 3b. Of course, the step 3b is formed behind the strainer 5 so as to support the strainer 5 with respect to the flow of oil.

이러한 스트레이너(5)는 독립적으로 분리되어 있기 때문에 주기적 교환 및 세척 후 재부착이 가능한 구조이다.Since the strainers 5 are independently separated, the strainer 5 can be reattached after periodic exchange and cleaning.

이와 같이, 본 고안에 의한 이물질 유출방지 구조를 갖는 오일펌프는 펌프 내부의 이물질이 스트레이너에 의해 걸러지기 때문에 기어박스의 작동불량을 미연에 방지하는 효과를 제공한다.As such, the oil pump having the foreign matter leakage preventing structure according to the present invention provides an effect of preventing the malfunction of the gearbox because the foreign matter inside the pump is filtered by the strainer.

또한, 본 고안에 의한 오일펌프는 스트레이너가 탈부착이 가능한 조립형이기 때문에 세척 후 재사용이 가능할 뿐만 아니라 새것으로도 용이하게 교체할 수 있다.In addition, the oil pump according to the present invention can be easily replaced by a new one as well as being reused after cleaning because the strainer is detachable and assembled.

본 고안은 상기 실시 예에 한정되지 않고 본 고안의 기술적 요지를 벗어나지 않는 범위 내에서 당해 기술분야의 통상의 지식을 가진 자에 의해 다양하게 변형 실시될 수 있다.The present invention is not limited to the above embodiments and may be variously modified and implemented by those skilled in the art without departing from the technical gist of the present invention.
