Abstract

PURPOSE: A drain valve of an engine lubricating oil filter is provided to allow easily removing a replacement type element. CONSTITUTION: A mounting part(30) and a protrusive part(40) are coupled in a sealing seat(20) so that oil moves along a drain pipe(80). A secondary spring(51) is coupled between the mounting part and a stopper extending to a lower side of the protrusive part. A primary spring(50) is coupled to a protrusion and the sealing seat on an outside of the stopper of the protrusive part. Elastic tension of the primary spring is weaker than the secondary spring so that the primary spring is pushed ahead of the secondary spring while the protrusive part simultaneously pushes the primary spring and the secondary spring. A replacement type element(70) is lifted by the primary spring and the secondary spring. A drain valve is forcibly inserted to an inlet of the drain pipe in a case. The drain valve is closed when the replacement type element is inserted. When a cover of the case is opened, the protrusive part is pushed by elastic force of the primary spring and the secondary spring. The protrusive part pushes a lower cap of the replacement type element to protrude.

Description

차량용 엔진 오일 여과기 드레인 밸브{Drain valve for engine lubricating oil filter}Drain valve for engine lubricating oil filter

본 발명은 차량의 엔진 내부를 순환하면서 윤활 및 냉각 작용을 행하는 엔진오일의 여과기에서 엘리멘트가 제거될 시에 오일이 자동적으로 배출될 수 있도록 하는 차량용 오일 여과기 드레인 밸브에 관한 것이다.The present invention relates to an oil strainer drain valve for a vehicle that allows oil to be automatically discharged when an element is removed from a strainer of engine oil that performs lubrication and cooling while circulating inside an engine of a vehicle.

종래의 엔진오일 여과기의 드레인 밸브의 경우, 오일 유입구과 여과된 오일이 나가는 오일 유출구를 갖는 케이스와 케이스 내부에 수용된 엘리멘트, 케이스에 나사 체결되는 뚜껑으로 구성되어 있다.The drain valve of a conventional engine oil filter consists of a case having an oil inlet and an oil outlet through which the filtered oil exits, an element housed inside the case, and a lid screwed to the case.

상기의 케이스는 알루미늄 재질로 다이캐스팅 제작되며, 오일 유출구와 오일 갤러리를 연결하는 유출통로 및 오일 유입구와 오일 펌프를 연결하는 유입통로를 갖는 접속구 몸체와, 상기 유입통로의 유입단에 설치되며, 오일의 역류방지를 위한 역류방지 밸브와 엘리멘트를 장시간 사용하여 여과재에 이물질이 일정치 이상 끼이게 되면, 여과재의 오일 여과성능이 하락하면서 오일 유입구의 오일 유입량에 비해 오일 유출구로의 오일 배출량이 현저히 감소되는 것을 방지하기 위한 릴리프 밸브로 구성되고, 특히, 엘리멘트 교환형 차량 오일 여과기일 경우에는 엘리멘트 교환 시에 오일이 케이스 내에 오일 그대로 유지한 체로 있기 때문에, 엘리멘트와 더불어 오일의 많은 양이 그대로 묻어서 나오며, 그럼으로 오일의 낭비를 발생하고, 엘리멘트 삽입 시에도 오일이 케이스에서 넘쳐, 교환작업시에 비효율적이며, 오일의 낭비가 심하고, 작업자에게도 불편하였음으로, 케이스 내에 오일이 배출 될 수 있는 연결관과 드레인 밸브를 장착하여, 엘리멘트를 삽입 시에는 상부 캡의 한 부분이 드레인 밸브를 가압하여, 드레인 입구를 막고, 엘리멘트 제거 시에는 드레인 밸브가 열려 오일이 오일 탱크로 빠져나가게 되는 구조를 이룬다.The case is made of aluminum die-casting, the connection body having an outlet passage connecting the oil outlet and the oil gallery and the inlet passage connecting the oil inlet and the oil pump, and is installed at the inlet end of the inlet passage, If foreign substances are caught in the filter media by using the non-return valve and the element to prevent the backflow for a long time, the oil filtration performance of the filter media is reduced and the oil discharge to the oil outlet is significantly reduced compared to the oil inlet of the oil inlet. It is composed of a relief valve to prevent, especially in the case of an element exchange type vehicle oil filter, since the oil remains in the case when the element is changed, the large amount of oil is buried together with the element. Generates waste of oil, Edo oil overflowed from the case, it was inefficient during replacement work, wasted oil and was inconvenient for the operator, so it was equipped with a connection pipe and a drain valve to discharge oil in the case. A portion of the pressurizes the drain valve to block the drain inlet, and upon removal of the element, the drain valve opens to allow oil to flow out into the oil tank.

그러나 종래의 드레인 밸브의 경우에서는 돌출부의 이동거리를 재한하는 스톱퍼와 실링시트의 이동거리를 제한하는 스톱퍼의 두가로 이루어져 있어, 그 기능이 복잡하고, 일차스프링과 이차스프링의 경우 엘리멘트가 삽입 시에 일차 스프링이 눌려져서, 스톱퍼에 닿은 후, 이차 스프링이 눌려지고, 케이스의 두껑이 열릴 경우에는 이차스프링 만이 엘리멘트를 밀어내는 역활을 함으로, 스프링의 탄성력이 엘리멘트에 완전히 전달되자 못함으로, 자동으로 엘리멘트가 빠지는데, 취약한 면이 발생하는 문제점이 있었다.However, in the case of the conventional drain valve, the stopper restricts the moving distance of the protrusion and the stopper limiting the moving distance of the sealing seat, and its function is complicated. In the case of the primary spring and the secondary spring, the element is inserted at the time of insertion. When the primary spring is pressed, touches the stopper, the secondary spring is pressed, and when the lid of the case is opened, only the secondary spring plays the role of pushing the element. There is a problem that occurs, the weak side occurs.

따라서, 상기 문제점을 해결하기 위한 본 발명은 교환형 엘리멘트(70)가 삽입 될 시에는 일차 스프링(50)과 이차 스프링(51)이 동시에 눌려져, 실링시트(20)에 안착부(30)가 접하여 오일이 배출되는 드레인 입구(23)가 막혀야 하며, 케이스의 두껑이 열릴 경우, 삽입되어 있는 교환형 엘리멘트(70)를 자동으로 밀어내기 위해, 일차 스프링(50)과 이차 스프링(51)의 탄성력이 동시에 교환형 엘리멘트(70)에 발휘되어 엘리멘트(70)가 자동으로 위로 밀려 올라가는 동시에 오일이 드레인 관(80)를 통하여 오일이 배출되는 작용을 하는 차량용 오일 여과기용 드레인 밸브를 제공함에 있다.Therefore, the present invention for solving the above problems when the exchangeable element 70 is inserted, the primary spring 50 and the secondary spring 51 is pressed at the same time, the seating portion 30 in contact with the sealing sheet 20 The drain inlet 23 through which the oil is discharged should be blocked, and when the lid of the case is opened, the elastic force of the primary spring 50 and the secondary spring 51 to automatically push out the inserted interchangeable element 70. At the same time to be exerted on the exchangeable element 70, the element 70 is automatically pushed up and at the same time the oil is discharged through the drain pipe 80 to provide a drain valve for an oil filter for a vehicle.

상기 목적 달성을 위한 본 발명의 특징은,Features of the present invention for achieving the above object,

실링시트(20)내에 안착부(30)와 돌출부(40)가 체결되어 오일이 드레인 관(80)에 따라 움직이게 되며, 안착부(30)와 돌출부(40) 아래측으로 뻗어 있는 스톱퍼(41)사이에 이차 스프링(51)이 체결되고, 돌출부(40)의 스톱퍼 바깥 측면에 돌출 턱(42)과 실링시트(20)에 일차 스프링(50)이 체결되는 구조를 이룬다. 그리고 일차스프링(50)의 탄성 장력을 이차스프링(51)보다 약하게 하여, 돌출부(40)가 두 스프링을 동시에 누르나, 실제로는 일차스프링(50)이 이차스프링(51)보다 먼저 눌려지게 하였으며, 케이스의 두껑이 열릴 경우에는 일차스프링(50)과 이차스프링(51)의 탄성력이 동시에 엘리멘트(70)에 가해져 교환형 엘리멘트(70)가 외부에서 주는 다른 힘의 작용이 없이도 스프링의 장력 만큼은 자동으로 밀려오라가는 것을 특징으로 한다.The seating portion 30 and the protrusion 40 are fastened in the sealing sheet 20 so that the oil moves along the drain pipe 80, and between the seating portion 30 and the stopper 41 extending below the protrusion 40. The secondary spring 51 is fastened to, and the primary spring 50 is fastened to the protrusion jaw 42 and the sealing seat 20 on the outer side of the stopper of the protrusion 40. Then, the elastic tension of the primary spring 50 is weaker than the secondary spring 51, so that the protrusions 40 simultaneously press the two springs, but in fact the primary spring 50 is pressed before the secondary spring 51, When the lid of the case is opened, the elastic force of the primary spring 50 and the secondary spring 51 is applied to the element 70 at the same time, so that the tension of the spring is automatically maintained without the action of other forces exerted by the exchangeable element 70 from the outside. It is characterized by a push.
