Description

연료 공급 루트{fuel supply routine}Fuel supply routine

본 발명은 연료공급루트 장치에 관한 것으로 연료압력 조절기와 리저버를 조합하여 연료탱크까지의 연료 리턴루트의 삭제가 가능하도록 하는 것이다.The present invention relates to a fuel supply route device to combine the fuel pressure regulator and the reservoir so that the fuel return route to the fuel tank can be deleted.

종래의 연료공급 루트는 연료펌프에 의해 연료 파이프 및 호스를 지나 딜리버리 파이프로 공급되고 각 인젝터로 분배되어지는데 압력 조절기는 흡입 매니폴드(intake manifold) 압력보다 항상 일정 압력 이상으로 유지하고 남은 연료는 연료 탱크로 되돌려 보내짐으로써 레이 아웃 측면상 각각의 파이프에 대한 루트를 설정해야 하므로 난해하다는 점과 하나의 루트에 비하여 비용이 상승되고 파이프 파손등으로 연료가 누설되는 가능성이 상승되는 문제가 발생되어 왔다.Conventional fuel supply routes are fed by fuel pumps to the delivery pipes through the fuel pipes and hoses and distributed to each injector. The pressure regulator is always kept above a certain pressure above the intake manifold pressure and the remaining fuel is fueled. As it is sent back to the tank, it is difficult to set the route for each pipe on the layout side, and it has been difficult, and the cost increases and the possibility of fuel leakage due to pipe breakage increases compared to one route. .

통상의 연료장치는 연료탱크에서 연료여과기를 통하여 연료펌프로 유입된다.Conventional fuel apparatus is introduced into the fuel pump through the fuel filter in the fuel tank.

연료펌프는 기계식 연료펌프, 전기식 연료펌프, 연료 진공조합식 펌프 등으로 나뉘며 기계식 연료 펌프는 두 개의 체크 밸브가 있는 펌프실에서 내유성이 있는 다이아프램(diaphram), 막스프링과 아래로 잡아 당기는 풀로드(pull rod), 로커암(rocker arm)으로 다이아프램의 상하운동에 따라 펌프실의 체적을 변화시켜 펌프 작용을 하게 되어 있으며 이는 캠축의 편심구동 캠에 의해 이뤄진다.Fuel pumps are divided into mechanical fuel pumps, electric fuel pumps, and fuel vacuum combination pumps. Mechanical fuel pumps are oil resistant diaphrams, membrane springs and pull-down pull rods in a pump room with two check valves. The pull rod and rocker arm change the volume of the pump chamber according to the up and down movement of the diaphragm to act as a pump. This is achieved by the cam shaft's eccentric drive cam.

구동캠이 회전하는 피봇 핀을 중심으로 하여 로커암이 밑으로 내려가 펌프실의 체적이 커지기 때문에 입구 밸브를 통하여 펌프실에 들어온다.The drive cam enters the pump chamber through the inlet valve because the rocker arm is lowered around the pivoting pin which rotates and the volume of the pump chamber is increased.

구동캠이 더 회전되어 로커암이 본래의 위치로 돌아가는 다이아프램이 다이아프램 스프링에 돌려지며 연료가 출구 밸브를 거쳐 배출된다.The drive cam is further rotated so that the diaphragm, where the rocker arm returns to its original position, is turned on the diaphragm spring and fuel is discharged via the outlet valve.

이 작동을 반복하여 연료를 기화기에 연속적으로 압송하여 기화기의 뜨개실의 유문이 규정의 높이가 되어 뜨개 밸브가 닫히면 연료로 흐르지 못한다.This operation is repeated to continuously feed fuel to the carburetor, so that the flow gate of the carcass of the carburetor is at the height specified and cannot flow into the fuel when the knitting valve is closed.

따라서 연료의 배출 압력도 다이아프램 스프링의 장력에 의해 조정이 된다.Therefore, the discharge pressure of the fuel is also adjusted by the tension of the diaphragm spring.

따라서 본 발명은 상기한 문제점을 해결하기 위하여 안출한 것으로 연료 압력 조절기와 리저버를 조합하여 연료 탱크까지의 연료 리턴 루터를 삭제함으로써 연료 파이프 장착 공정을 단순화하고 연료 리턴 파이프 및 고정용 브라켓트류, 호스, 조인트 등을 감소하는 것을 목적으로 한다.Therefore, the present invention has been made in order to solve the above-mentioned problems by simplifying the fuel pipe mounting process by eliminating the fuel return router to the fuel tank by combining the fuel pressure regulator and the reservoir, and the fuel return pipe and fixing brackets, hoses, The purpose is to reduce joints and the like.

따라서 연료 압력 조절기(1)는 흡입 매니홀드(8) 압력보다 항상 일정 압력이상으로 유지하고 남은 연료는 연료탱크(6)로 되돌려 보낸다.Therefore, the fuel pressure regulator 1 is always kept above a certain pressure than the intake manifold 8 pressure and the remaining fuel is returned to the fuel tank 6.

이를 위하여 본 발명은 델리버리 파이프(16) 연료 압력이 일정치 이상일 경우, 이 압력에 의해 밸브(15)가 닫혀 연료 공급이 되지 않고 리저버(14)에서 머무르게 되고 델리버리 파이프(15) 연료 압력이 일정치 이하일 경우 스프링(17) 탄성력에 의해 밸브(15)가 열리고 연료가 공급된다.To this end, in the present invention, when the delivery pressure of the delivery pipe 16 is greater than or equal to a predetermined value, the valve 15 is closed due to this pressure, thereby remaining in the reservoir 14 without being supplied with fuel, and the delivery pressure of the delivery pipe 15 is increased. When the predetermined value or less, the valve 15 is opened by the spring 17 elastic force and the fuel is supplied.

이상에서 설명된 본 발명의 구성에 의거하여, 상기한 연료 공급 루트는 연료 압력 조절기와 리저버(14)를 조합하여 연료탱크(12)까지의 연료 리턴 루트를 삭제시킨다.Based on the configuration of the present invention described above, the fuel supply route eliminates the fuel return route to the fuel tank 12 by combining the fuel pressure regulator and the reservoir 14.
