More specifically, the height of the shaft is adjusted by adjusting the thickness of the height adjusting washer assembled to the timing rod. The present invention relates to a fuel injection pump for a diesel internal combustion engine that is simpler in structure and easier to adjust in an initial position by changing the initial position of the control sleeve.

분사시기 가변기구를 구비한 종래의 연료분사펌프는 도 3내지 도 4의 도시와 같이 펌프본체(1)에 플런져 배럴(3)이 고정되고, 이에 플런져(4)가 캠(10)에 따라 왕복 운동을 하게 된다.In the conventional fuel injection pump having a variable injection timing mechanism, the plunger barrel 3 is fixed to the pump body 1 as shown in FIGS. 3 to 4, and the plunger 4 is connected to the cam 10. I will reciprocate.

상기 플런져(4)에는 연료체류실(18)로 통하는 연료흡입배출구멍(24)이 형성되어 있으며, 그 상부에는 제어슬리브(17)가 슬라이딩 되도록 구성되어 있다.The plunger 4 is provided with a fuel suction discharge hole 24 which leads to the fuel retention chamber 18, and is configured such that the control sleeve 17 slides thereon.

제어슬리브(17)에 대하여 타이밍로드(29)가 직교하여 설치되고, 타이밍로드(29)의 직경방향에 관통하는 창부(32)가 상기 제어슬리브(17)에 대향하여 형성되어 있고, 이에 원반상의 본체부(34)가 창부(32)에 형성된 계단부(35)와 슬라이딩 되도록 형성된 접촉샤프트(33)가 삽입되어 있다.The timing rod 29 is orthogonal to the control sleeve 17, and a window portion 32 penetrating in the radial direction of the timing rod 29 is formed to face the control sleeve 17. The contact shaft 33 formed so that the main body 34 slides with the step part 35 formed in the window part 32 is inserted.

또한 접촉샤프트(33)는 본체부(34)와 일체로 접촉핀부(36)를 가지고 있고, 이 접촉핀부(36)는 본체부(34)에 대하여 편심으로 설치되는 동시에 창부(32)로부터 제어슬리브(17) 측으로 돌출하여 제어슬리브(17)의 접촉홈(22)에 끼워진다.In addition, the contact shaft 33 has a contact pin portion 36 integrally with the main body portion 34, which is provided eccentrically with respect to the main body portion 34, and at the same time the control sleeve from the window portion 32. It protrudes to the side (17) and is fitted in the contact groove 22 of the control sleeve 17.

또, 접촉샤프트(33)의 접촉핀부(36)의 반대측에는 조정로드(37)가 본체부(34)와 일체로 되어 있고, 이 조정로드(37)는 압입나사(38)에 형성된 중심구멍(39)을 통하게 되며, 압입나사(38)는 상기 창부(32)에 나사결합하여 와셔(40)를 거쳐서 접촉샤프트(33)의 본체부(34)를 누른다.On the opposite side of the contact pin portion 36 of the contact shaft 33, an adjusting rod 37 is integrated with the main body portion 34, and the adjusting rod 37 has a center hole formed in the press-fit screw 38. 39, the press-fit screw 38 is screwed to the window portion 32 to press the main body portion 34 of the contact shaft 33 via the washer 40.

그리하여 상기 제어슬리브(17)와 타이밍로드(29)가 분사시기 가변기구를 구성하고 있고, 타이밍로드(29)가 회전하면 제어슬리브(17)가 상하방향으로 이동하므로서 제어슬리브(17)와 상기 플런져(4)와의 상하방향의 상대위치가 변하여 분사시기를 조절할 수 있는 것이다.Thus, the control sleeve 17 and the timing rod 29 constitute a variable injection timing mechanism. When the timing rod 29 rotates, the control sleeve 17 and the control sleeve 17 move in the vertical direction. The relative position in the up and down direction with the launcher 4 is changed to control the injection timing.

그러나 상기와 같은 구성의 종래 디젤내연기관용 연료분사펌프는 타이밍로드에 창부와 계단부가 복잡하게 가공되어 있고, 접촉샤프트와 압입나사의 조립공정이 까다로워 제작비용이 많이 소요될 뿐만 아니라, 제어슬리브의 초기위치 조절이 까다로운 문제점이 있었다.However, the conventional fuel injection pump for diesel internal combustion engines having the above-described configuration has complicated processing on the window rod and the stepped portion of the timing rod, and the manufacturing process of the contact shaft and the press-fit screw is complicated, which makes the manufacturing cost expensive, and the initial position of the control sleeve Problems were difficult to control.

본 발명은 상기와 같은 문제점을 해결하기 위하여 분사시기 가변기구를 구비한 연료분사펌프의 타이밍로드의 일측에, 접촉핀부를 구비하고 하측에 높이 조정용 와셔의 두께에 의하여 상하로 조정이 가능한 티자형 샤프트를 설치하여, 티자형 샤프트의 접촉핀부가 제어슬리브의 축방향 위치를 결정하도록 하여 분사시기의 변화가 가능하도록 하므로서 조립시 제어슬리브와 타이밍로드의 연결이 용이함은 물론, 제어슬리브의 초기위치 조절이 용이한 디젤내연기관용 연료분사펌프를 제공코저 한 것이다.The present invention is to solve the problems as described above, one side of the timing rod of the fuel injection pump having a variable injection timing mechanism, provided with a contact pin portion, the lower side can be adjusted up and down by the thickness of the height adjustment washer By installing the contact pins of the T-shaft shaft to determine the axial position of the control sleeve so that the injection timing can be changed, and the control sleeve and timing rod can be easily connected during assembly.

도 1 내지 도 2는 본 발명 디젤내연기관용 연료분사펌프의 전체단면도와, 타이밍 로드와 제어슬리브를 나타낸 분리 사시도로써, 열형의 연료분사펌프는 펌프 본체(1)에 엔진의 기통수에 대응하는 종방향 구멍(2)이 있고, 이 종방향 구멍(2) 내에서 플런져 배럴(3)이 압입되고, 플런져배럴(3) 내에서 플런져(4)가 습동하도록 되어 있다.1 to 2 are separated cross-sectional views of the fuel injection pump for a diesel internal combustion engine of the present invention, showing a timing rod and a control sleeve, wherein the thermal fuel injection pump has a type corresponding to the number of cylinders of the engine in the pump main body 1; There is a directional hole 2, the plunger barrel 3 is press-fitted in the longitudinal hole 2, and the plunger 4 slides in the plunger barrel 3.

플런져(4)의 상단과 델리버리밸브(6)는 펌프 본체(1)에 고정된 밸브 하우징(5)안으로 삽입되고, 델리버리밸브(6)와 플런져(4)의 사이에 연료압력실(7)이 형성되고, 델리버리밸브(6)의 상부에는 연료출구(8)가 구성되어 있다.The upper end of the plunger 4 and the delivery valve 6 are inserted into the valve housing 5 fixed to the pump body 1 and between the delivery valve 6 and the plunger 4 the fuel pressure chamber. (7) is formed, and the fuel outlet 8 is comprised in the delivery valve 6 upper part.

또한, 플런져(4)의 하단은 타페트(11)를 통하여 캠축(9)에 형성된 캠(10)에 연결되고, 캠축(9)은 엔진과 연결되어 회전하며 스프링(12)과 함께 플런져(4)를 캠(10)의 형상에 따라 상하 방향으로 왕복운동하게 된다.In addition, the lower end of the plunger 4 is connected to the cam 10 formed on the camshaft 9 through the tappet 11, the camshaft 9 is connected to the engine and rotates, and the plunger together with the spring 12. (4) is reciprocated in the vertical direction in accordance with the shape of the cam (10).

그리고 상기 플런져(4)에는 중심에 축방향으로 연료구멍(25)과 반경방향으로는 연료흡입배출구멍(24)이 형성되어 연료체류실(18)과 통하게 되어 있고, 연료체류실(18)은 펌프본체(1)에 형성된 횡방향 구멍(19)을 거쳐 연료입구(20)와 통하게 되어 있다. 또한, 플런져(4)의 외면에는 경사홈(26)과 세로홈(27)이 형성되어 있으며 연료흡입배출구멍(24)과 홈으로 연결되어 있다.The plunger 4 has a fuel hole 25 in the axial direction and a fuel suction discharge hole 24 in the radial direction at the center thereof to communicate with the fuel retention chamber 18. Is communicated with the fuel inlet 20 via a lateral hole 19 formed in the pump body 1. In addition, the outer surface of the plunger 4 is formed with an inclined groove 26 and the longitudinal groove 27 is connected to the fuel suction discharge hole 24 and the groove.

그리고, 플런져(4)에는 평탄부(13)가 형성되어 있으며 분사량 조절용 슬리브(14)에 끼워지고, 이 슬리브(14)의 상부에 있는 돌출핀(15)이 분사량 조절용 랙크(16)에 삽입되므로, 분사량 조절용 랙크(16)의 움직임에 의해 플런져(4)를 회전 시킬 수 있다.Then, the plunger 4 has a flat portion 13 formed therein, and is fitted in the injection volume adjusting sleeve 14, and the protruding pin 15 on the upper portion of the sleeve 14 is inserted into the injection volume adjusting rack 16. Therefore, the plunger 4 can be rotated by the movement of the injection amount adjusting rack 16.

제어슬리브(17)는 상기 플런져 배럴(3)내에 형성된 연료체류실(18)에 위치하여 플런져(4)의 외경과 슬라이딩되고, 반경방향에 관통구멍(28), 축방향에 안내홈(21)과 가로방향에 접촉홈부(22)가 설치되어 있고, 안내홈(21)은 플런져 배럴(3)에 압입된 안내핀(23)에 끼워져 축방향으로 운동하도록 하고, 접촉홈부(22)는 티자향 샤프트(44)의 접촉핀부(36)를 통하여 타이밍로드(29)와 연결된다.The control sleeve 17 is located in the fuel retention chamber 18 formed in the plunger barrel 3 and slides with the outer diameter of the plunger 4, the through hole 28 in the radial direction, and the guide groove in the axial direction. 21 and a contact groove 22 is provided in the transverse direction, the guide groove 21 is fitted to the guide pin 23 pressed into the plunger barrel 3 to move in the axial direction, the contact groove 22 Is connected to the timing rod 29 through the contact pin portion 36 of the tee-shaft shaft 44.

이와 같은 구성의 본 발명 디젤내연기관용 연료분사펌프의 작용을 보면, 플런져(4)가 하사점으로부터 상승시에는 상기의 연료흡입배출구멍(24)이 연료체류실(18)에 열려 있고, 연료압력실(7)은 연료구멍(25)과 연료흡입배출구멍(24)을 거쳐 연료체류실(18)로 통하고 있으므로, 연료압력실(7)내의 연료의 압력은 상승하지 않고 델리베리밸브(6)가 닫혀 있게 된다.When the plunger 4 rises from the bottom dead center, the fuel suction discharge hole 24 is opened in the fuel retention chamber 18 when the plunger 4 rises from the bottom dead center. Since the chamber 7 communicates with the fuel retention chamber 18 via the fuel hole 25 and the fuel suction discharge hole 24, the pressure of the fuel in the fuel pressure chamber 7 does not increase, and the delivery valve 6 ) Will be closed.

이 상태로 부터 플런져(4)가 더욱 상승하여 연료흡입배출구멍(24)이 제어슬리브(17)의 밑면보다 높게 위치하면 연료흡입배출구멍(24)이 제어슬리브(17)의 내면에 의해 막히게 되므로 연료압력실(7)내의 압력이 상승하여 델리베리밸브(6)가 열리고 연료가 분사 된다.From this state, if the plunger 4 rises further and the fuel suction discharge hole 24 is positioned higher than the bottom of the control sleeve 17, the fuel suction discharge hole 24 is blocked by the inner surface of the control sleeve 17. Therefore, the pressure in the fuel pressure chamber 7 rises, the delivery valve 6 opens, and the fuel is injected.

이와 같이 플런져(4)가 하사점으로 부터 연료흡입배출구멍(24)을 막아서 연료가 분사될 때까지의 플런져(4)의 변위가 분사개시전 행정(프리 스트로크)이다.In this way, the displacement of the plunger 4 until the plunger 4 blocks the fuel intake discharge hole 24 from the bottom dead center and the fuel is injected is a stroke before the start of injection (free stroke).

그리고 더욱 플런져(4)가 상승하여 경사홈(26)이 제어슬리브(17)의 관통구멍(28)과 만나면 연료압력실(7)내의 연료가 연료구멍(25), 연료흡입배출구멍(24), 세로홈(27), 경사홈(26) 및 관통구멍(28)의 경로를 거쳐 연료체류실(18)로 빠져 나오게 되어 연료압력실(7)내의 연료압력은 하강하고 델리베리밸브(6)는 닫히게 되므로 연료분사가 종료된다. 이와 같이 분사개시로부터 분사종료까지의 플런져(4)의 변위가 유효행정(유효 스트로크)이다.Further, when the plunger 4 is raised so that the inclined groove 26 meets the through hole 28 of the control sleeve 17, the fuel in the fuel pressure chamber 7 is fuel hole 25 and fuel suction discharge hole 24. ), The longitudinal grooves 27, the inclined grooves 26, and the through-holes 28 pass through the fuel retention chamber 18 so that the fuel pressure in the fuel pressure chamber 7 drops and the delivery valve 6 ) Is closed, so the fuel injection ends. In this way, the displacement of the plunger 4 from the start of injection to the end of injection is an effective stroke (effective stroke).

이 유효행정은 전기한 분사량 조절용 랙크(16)로 플런져(4)를 회전시키므로서 조절되고, 분사개시전 행정은 타이밍로드(29)로 제어슬리브(17)를 상하로 움직이므로서 조절이 가능하다.This effective stroke is adjusted by rotating the plunger 4 with the rack 16 for adjusting the injection amount, and the stroke before starting the injection can be adjusted by moving the control sleeve 17 up and down with the timing rod 29. .

타이밍로드(29)는 횡방향 구멍(19)에 삽입되어 펌프본체(1)에서 회전하도록 되어 있고, 타이밍로드(29)의 직경방향에 안내홈부(46)가 있고, 이 안내홈부(46)에 높이조정 와셔(43)와 그 위에 티자형 샤프트(44)가 삽입되어 있다.The timing rod 29 is inserted into the lateral hole 19 so as to rotate in the pump body 1, and the guide groove 46 is provided in the radial direction of the timing rod 29, and the guide groove 46 The height adjusting washer 43 and the tee-shaped shaft 44 are inserted thereon.

티자형 샤프트(44)는 접촉핀부(36)와 나사부(45)를 가지며, 나사부(45)는 타이밍로드(29)의 안내홈부(46)의 구멍을 통과하여 스프링와셔(42)를 거쳐 너트(41)와 나사결합을 하며, 접촉핀부(36)는 제어슬리브(17)의 접촉홈(22)에 끼워지게 된다. 이때, 타이밀로드(29)가 회전하면 제어슬리브(17)가 상하방향으로 움직이므로 이 제어슬리브(17)와 플런져(4)와의 상하 방향으로 상대위치가 변하게 된다.Tee-shaped shaft 44 has a contact pin portion 36 and a threaded portion 45, the threaded portion 45 passes through the hole of the guide groove 46 of the timing rod 29 through the spring washer 42 through the nut ( 41 is screwed, and the contact pin portion 36 is fitted into the contact groove 22 of the control sleeve 17. At this time, when the tie mill rod 29 rotates, the control sleeve 17 moves in the up and down direction, so that the relative position of the control sleeve 17 and the plunger 4 changes in the up and down direction.

그러므로 플런져(4)의 유효행정은 변하지 않았지만 분사개시 및 분사종료의 타이밍이 변화되는 것이다.Therefore, although the effective stroke of the plunger 4 has not changed, the timing of the start of injection and the end of injection is changed.

이와 같이 분사시기 가변기구를 조립할 때에 각 기통마다 분사타이밍을 조정할 필요가 있다면, 위에서 설명한 바와 같이 타이밍로드(29)에 높이조정 와셔(43)와 티자형 샤프트(44)가 조립되므로, 높이조정 와셔(43)의 두께만 변경하면 티자형 샤프트(44)와 일체로 된 접촉핀부(36)의 상하 방향으로 위치가 변하여 제어슬리브(17)의 위치를 용이하게 조정할 수 있는 것이다.If the injection timing needs to be adjusted for each cylinder when assembling the injection timing variable mechanism as described above, the height adjustment washer 43 and the tee-shaft 44 are assembled to the timing rod 29 as described above. If only the thickness of 43 is changed, the position changes in the vertical direction of the contact pin portion 36 integrated with the tee-shaft 44 so that the position of the control sleeve 17 can be easily adjusted.

이와 같이 본 발명은 분사시기 가변기구를 구비한 연료분사펌프의 타이밍로드의 일측에, 접촉핀부를 구비하고 하측에 높이 조정용 와셔의 두께에 의하여 상하로 조정이 가능한 티자형 샤프트를 설치하여, 티자형 샤프트의 접촉핀이 제어슬리브의 축방향 위치를 결정하도록 하여 분사시기의 변화가 가능하도록 하므로서 조립시 제어슬리브와 타이밍로드의 연결이 용이함은 물론, 제어슬리브의 초기위치 조절이 용이하여 제작원가를 절감 시킬 수 있는 효과가 있는 것이다.As described above, the present invention provides a tee type shaft having a contact pin portion at one side of a timing rod of a fuel injection pump having a variable injection timing mechanism and a tee type shaft which can be adjusted up and down by the thickness of the height adjusting washer at the lower side. The contact pin of the shaft determines the axial position of the control sleeve, which enables the injection timing to be changed, making it easy to connect the control sleeve and the timing rod when assembling, and the initial position of the control sleeve can be easily adjusted to reduce manufacturing costs. There is an effect that can be made.
