Abstract

The pressure regulator is for fuel injection system of a spark ignition engine. The regulator is regulated for pressure at which fuel is delivered to the fuel injectors, this pressure being constantly referenced to a predetermined value for the purpose of maintaining the correct air/fuel mix-ture-ratio for all conditions of use of the engines. The regulator comprises an arrangement of various mechanical components which divide the flow of fuel delivered by a supply pump into two parts. One part of this flow is supplied to the injectors which take up the quantity required by the operating conditions of the engine. The remaining part is returned to the motor vehicle tank.

Description

점화제어 내연기관의 분사시스템용 압력 조정기Pressure regulator for injection system of ignition control internal combustion engine

제1도는 본 발명에 따른 조정기의 대칭축을 보지하는 면의 부분 단면도.1 is a partial cross-sectional view of a face holding the axis of symmetry of a regulator according to the invention.

제2도는 제1도의 조정기의 일부를 형성하는 밸브부재의 부분단면도.2 is a partial cross-sectional view of the valve member forming part of the regulator of FIG.

본 발명은 압력조정기에 관한 것으로, 특히 1978. 7. 2자 이탈리아 공화국 특허출원 제3325A/78호의 주요부를 형성하는 것의 기능적 부재를 갖는 점화제어 내연기관의 분사시스템용 압력조정기에 관한 것이다.The present invention relates to a pressure regulator, and more particularly, to a pressure regulator for an injection system of an ignition control internal combustion engine having a functional member for forming a major part of the Patent Application No. 3325A / 78 of July 2, 1978.

상기 특허출원에 기재된 조정기의 특징은 그 중심이 그것을 한정하며 탱크에의 귀환관의 입구를 제어하는 표면 내에 보지된 반구(hemisphere)에 의해 구성된 밸브를 사용하는 것이다. 이 밸브는 다이어프램과 일체인 지지부내에 형성된 공동의 벽과 접촉 유지되도록 탄성력이 작용되므로 밸브의 이동은 지지부의 이동과 동일하다.A feature of the regulator described in the patent application is the use of a valve constituted by a hemisphere held in the surface whose center defines it and controls the inlet of the return tube to the tank. Since the valve is applied with an elastic force to keep in contact with the wall of the cavity formed in the support integral with the diaphragm, the movement of the valve is the same as the movement of the support.

이 압력 조정기는 그전에 특허출원된 것과 달리 신규성이 있고 독창적이고 기술적으로 유효한 형상의 구조를 제안한다. 그러나, 상기 기술은 대량 생산의 경우에 해결하기 힘든 구조 및 조립상의 문제점을 내재한다.This pressure regulator offers a novel, original and technically effective construction of the structure, which has not been previously patented. However, this technique introduces structural and assembly problems that are difficult to solve in case of mass production.

본 발명의 목적은 상기 특허출원에서 제기된 대량 생산에서 발생하는 구조 및 조립상의 문제점을 밸브에 의해 해결할 수 있는 점화제어 내연기관의 분사시스템용 압력조정기를 제공하는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a pressure regulator for an injection system of an ignition control internal combustion engine that can solve the structure and assembly problems arising in the mass production filed in the patent application by means of a valve.

이하 첨부도면에 의해 본 발명은 상세히 설명한다.Hereinafter, the present invention will be described in detail by the accompanying drawings.

제1도에 도시된 조정기는 다이어프램(2)에 의해 2개의 비-연통 챔버(non-communicating chamber)로 내부가 구분된 금속 케이싱(1)에 구성된다. 챔버(2)는 다이어프램(2)에 추가하여 하우징(30)에 의해 한정된다. 챔버(4)는 상기 다이어프램(2)에 추가하여 하우징(40)에 의해 한정된다.The regulator shown in FIG. 1 is constructed in a metal casing 1 which is internally divided into two non-communicating chambers by a diaphragm 2. The chamber 2 is defined by the housing 30 in addition to the diaphragm 2. The chamber 4 is defined by the housing 40 in addition to the diaphragm 2.

상기 두 하우징 (3)(4)의 연부(31)(41)는 다이어프램(2)을 지지하며, 링(9)에 의해 함께 클램프 되고, 그 일부(90)(92)는 각기 연부(31)(41)의 원추대부(32)(45)상에 놓인다.The edges 31, 41 of the two housings 3, 4 support the diaphragm 2 and are clamped together by a ring 9, a portion 90, 92 of which is respectively edge 31. It lies on the cone 32, 45 of (41).

챔버(3)는 관(10)위에 설치된 도시하지 않은 제1관에 의해 입구 매니폴드 (intake manifold)에 연결된다. 따라서, 입구 매니폴드의 기준압력은 챔버(3) 내에 설정된다.The chamber 3 is connected to an intake manifold by a first tube, not shown, installed on the tube 10. Thus, the reference pressure of the inlet manifold is set in the chamber 3.

챔버(4)는 관(11)의 양방에 설치된 도시하지 않은 제2관에 의해 연료 공급펌프에 연결되고, 관(12)의 상방에 설치된 도시하지 않은 제3관에 의해 분사 시스템의 분사기에 연결되며, 또한 접속관(5)의 상방에 설치된 도시하지 않은 제4관에 의해 차량연료탱크에 연결된다.The chamber 4 is connected to the fuel supply pump by a second pipe (not shown) installed on both sides of the pipe 11 and connected to the injector of the injection system by a third pipe (not shown) installed above the pipe 12. It is also connected to the vehicle fuel tank by a fourth pipe (not shown) installed above the connection pipe (5).

만약 좀더 간단하게 구성하고져 하면 상기 입구접속기(11)(12)들을 하나로 줄일수도 있다. 접속관(5)은 하우징(40)의 하부에 구비된 관통 보어(44) 내에 삽입된 부분(50)을 갖는다. 관통보어(44)의 정부에 그리고 동일 축상에는 평면도로 다각형이며, 회전을 방지하기 위해 관(5)의 육각헤드를 보지하는 시이트(46)가 있다.If the configuration is simpler, the inlet connectors 11 and 12 can be reduced to one. The connection pipe 5 has a portion 50 inserted into the through bore 44 provided in the lower portion of the housing 40. At the top of the through bore 44 and on the same axis there is a sheet 46 which is polygonal in plan view and which holds the hexagonal head of the tube 5 to prevent rotation.

원추대 표면(43)은 관통보어(44)를 시이트(46)에 연결한다. 상기 관(5)의 일부를 형성하는 원추대 표면(52)은 그속에 배치된다. 이러한 커플링은 챔버(4)의 외부를 향해서 양호한 연료 시일을 제공하며, 이 시일은 관(5)의 나사부(53)상에 배치된 니트의 조임 효과에의해 향상된다. 관(5)은 또한 밸브시이트를 구성하는 부재(6)가 삽입되는 곳으로 원추구획부(54)를 구성한다.The cone surface 43 connects the through bore 44 to the sheet 46. Conical surface 52 forming part of the tube 5 is disposed therein. This coupling provides a good fuel seal towards the outside of the chamber 4, which is enhanced by the tightening effect of the nits disposed on the threaded portion 53 of the tube 5. The pipe 5 also constitutes a conical compartment 54 where the member 6 constituting the valve seat is inserted.

평탄한 밸브 시이트(61) 및 원형림(circular rim)에 의해 한정된 평탄면(62)은 부재(6)의 가장주요한 부분이다. 관(5)에 의해 구성된 부재(6)는 출구 노즐을 구성하며, 제2챔버(4) 내로 신장한다. 평탄한 시이트(61)는 밸브(7)의 평탄면에 의해 제어된다. 스프링(63)은 밸브(7)상에 구비된 유사한 표면(73) 및 원형림표면(62)사이에 배치된다. 스프링(63)은 밸브(7)의 구형 부분이 켑(20)에 의해 다이어프램(2)과 결합된 지지부(8)내에 구비된 구획부(80)의 원추면(81)과 접촉하게 한다.The flat surface 62 defined by the flat valve seat 61 and the circular rim is the most important part of the member 6. The member 6 constituted by the tube 5 constitutes an outlet nozzle and extends into the second chamber 4. The flat sheet 61 is controlled by the flat surface of the valve 7. The spring 63 is disposed between the similar surface 73 and the circular rim surface 62 provided on the valve 7. The spring 63 causes the spherical portion of the valve 7 to contact the conical surface 81 of the partition 80 provided in the support 8 coupled with the diaphragm 2 by a fin 20.

제어스프링(21)의 하단부는 켑(20)상에 작용하며, 그 타단부는 스프링 지지 켑(22)에 의해 지지된다. 이 스프링 지지켑은 하우징(30)의 정부상의 돌기부(33)를 횡단하는 나사보어(32) 내로 삽입된 육각구멍붙이 나사(13)의 원추점(14)을 내장하는 중앙보어(23)를 갖는다. 나사(13)를 조정함으로써 스프링(21)은 한정치로 예비 하중을 걸수 있다. 나사보어는 상향으로 넓어져서 팽창켑(15)을 보지하는 원통형 구획부(34)가 되어 미숙련공에 의한 나사(13)의 조정을 방지한다.The lower end of the control spring 21 acts on the jaw 20, the other end of which is supported by a spring support jaw 22. This spring support has a central bore 23 incorporating the conical point 14 of the hexagon socket head screw 13 inserted into the screw bore 32 traversing the top projection 33 of the housing 30. . By adjusting the screw 13, the spring 21 can be preloaded to a limited value. The screw bore widens upward to become a cylindrical partition 34 which holds the inflation fins 15 to prevent adjustment of the screw 13 by unskilled holes.

제2도는 제1도의 구획부(80) 내에 배치된 밸브(7)를 상세히 나타낸 것이다. 상기 밸브(7)는 보올 및 소켓 이음을 형성하기 위해 구획부(80)의 원추 대부(81)와 접촉하는 구형부(72)와 과도한 연료를 위한 유출부를 한정하는 평탄한 시이트(61)를 향하는 평면(75)과, 그 위에 스프링(63)의 상단부가 놓이는 원형림 형상의평면(73)과, 표면(73)과 표면(75)을 함께 연결하며 그위로 조정기 일체의 조립에 선행하는 단계중 스프링(63)이 수개소 터언(turn)하는 원통형 표면부(74)와, 상기 평면(75)에 수직되게 구비된 데드보어(76)(dead bore)와, 평면(75)과 대향하는 밸브(7)의 2구역 내에 배치된 평면(71) 상방으로 신장하는 원통형스텝(70)으로 구성된다.2 shows in detail the valve 7 arranged in the compartment 80 of FIG. 1. The valve 7 faces the flat sheet 61 which defines a spherical portion 72 in contact with the conical portion 81 of the partition 80 and an outlet for excess fuel to form a bowl and socket joint. A spring in the stage preceding the assembly of the regulator integral thereon with the 75 and the circular rim-shaped plane 73 on which the upper end of the spring 63 is placed, and the surface 73 and the surface 75 connected together. Cylindrical surface portion 74 in which 63 turns, a dead bore 76 provided perpendicular to the plane 75, and a valve 7 facing the plane 75. It is composed of a cylindrical step 70 extending above the plane 71 disposed in the two zones.

상기 밸브(7)는 스템(70)과 데드보어(76)의 대칭축과 일치하는 대칭축 A-A를 갖는다. 구면대(spherical sector)의 중심(C)은 평면(75)에 평행인 면 내 또는 평면(75) 내에 보지되지만 하향으로 배치된다.The valve 7 has an axis of symmetry A-A coinciding with the axis of symmetry of the stem 70 and the dead bore 76. The center C of the spherical sector is retained in the plane parallel to the plane 75 or in the plane 75 but arranged downward.

이것과 직접 관련되지는 않더라도 평면(75) 내에 밸브(7)의 회전중심(C)을 배치하는 것의 중요성을 도시하기 위해 압력조정기의 작동이 간단히 서술될 것이다. 기관 작동중 관(12)에 의해 제어 챔버(4)에 연결된 분사연료 공급관 내의 압력과 그 속에 분사기가 배치된 입구 매니폴드 내의 압력의 차이는 기관의 모든작동상태에 대하여 일정하게 유지되어야 한다. 이러한 목적을 달성하기 위해서 조정기는 노즐(6)의 시이트(61) 및 표면(75) 사이에 한정된 배출 면적을 변화시킨다. 매니폴드 압력이 증가한다고 가정하면 상기 압력차를 일정하게 유지하기 위해 전술한 바와 같이 매니폴드 내의 압력이 설정되는 챔버(3)를 향하는 측상의 다이어프램(2) 상에 작용하는 압력증가에 기인한 추력에 의해 평면(75)은 노즐(61)에 접근한다. 탱크로 귀환하기 위한 단면의 감소는 챔버(4) 내의 압력이 챔버(3) 내의 압력증가와 동일한 값만큼 증가하게 하여, 입구 매니폴드와 분사연료 공급관 사이의 압력차를 일정하게 유지한다. 매니폴드 압력이 강하하면 조정기는 유사한 기구에 의해 노즐(61)로부터 평면(75)을 발취함으로써 분사기 공급압력을 필요에 따라 조정한다.Although not directly related to this, the operation of the pressure regulator will be briefly described to show the importance of placing the center of rotation C of the valve 7 in the plane 75. The difference between the pressure in the injection fuel supply pipe connected to the control chamber 4 by the pipe 12 during the engine operation and the pressure in the inlet manifold with the injector disposed therein must be kept constant for all operating conditions of the engine. To achieve this goal, the regulator changes the discharge area defined between the sheet 61 and the surface 75 of the nozzle 6. Assuming that the manifold pressure increases, the thrust due to the pressure increase acting on the diaphragm 2 on the side towards the chamber 3 in which the pressure in the manifold is set, as described above, to keep the pressure difference constant. The plane 75 thereby approaches the nozzle 61. The reduction of the cross section for returning to the tank causes the pressure in the chamber 4 to increase by the same value as the pressure increase in the chamber 3, thereby maintaining a constant pressure difference between the inlet manifold and the injection fuel supply pipe. When the manifold pressure drops, the regulator adjusts the injector supply pressure as necessary by extracting the plane 75 from the nozzle 61 by a similar mechanism.

특허출원 제3325A/78호에 기재된 것에 비하여 본 발명의 구조는 후술하는 바와 같이 제조가 보다 용이해지며, 밸브(7)의 자기 안정 특성이 증가하므로, 밸브상의 폐쇄력의 작용점을 평면(75)에 의해 한정된 제어면보다 훨씬 하방으로 변위시킬 수 있고, 밸브(7)의 원형림 상에 놓인 스프링(63)에 의한 개방력을 평면(75)보다 훨씬 상방으로 변위시킬 수 있다.Compared to that described in Patent Application No. 3325A / 78, the structure of the present invention is easier to manufacture as described below, and the self-stable characteristics of the valve 7 are increased, so that the action point of the closing force on the valve is flat (75) It is possible to displace much lower than the control surface defined by, and the opening force by the spring 63 lying on the circular rim of the valve 7 can be displaced far above the plane 75.

본 발명은 특히 생산 및 조립 문제를 해결한다. 밸브(7)는 적당한 재료의 원통형 바아로부터 시작하는 자동 공작기계의 가공에 의해 생산될 수 있다. 각종 방법으로 밸브(7)를 대량 생산할 수 있는데 간단히 하기 위해서 2가지 방법만 기술하겠다.The present invention particularly addresses the problem of production and assembly. The valve 7 can be produced by the machining of an automatic machine tool starting from a cylindrical bar of suitable material. The valve 7 can be mass-produced in various ways. For simplicity, only two methods will be described.

제1방법은 자동선반 상의 성형 공구를 사용하는 것이다. 이 공구의 형상은 바아가 회전축 A-A에 대해 회전할때 보어(76)를 제외하고 밸브(7)를 발생하는 모양에 상응한다. 상기 보어(76)는 드릴 비트에 의해 형성된다.The first method is to use a molding tool on an automatic lathe. The shape of this tool corresponds to the shape that generates the valve 7 except for the bore 76 when the bar rotates about the axis of rotation A-A. The bore 76 is formed by a drill bit.

제2방법은 밸브(7)를 완전히 한정하기 위해 횡공급에 의해 진행하는 프로그램된 선반을 사용하는 것이다. 밸브(7)의 대칭축을 한정하는 스템(70)의 목적을 위해 평면(75)의 조도는 조정기의 정확한 작동을 위해 아주 낮게 유지되어야 한다. 아주 낮은 조도의 표면을 얻기 위해서 밸브(7)를 한정한 후 평면(75)을 래핑 가공하여야 한다. 이 가공은 단일 고정구에 의해 보지될 수 있는 가장 많은 부재에 대해 행해질 수 있다.The second method is to use a programmed lathe running by lateral feed to fully define the valve 7. For the purpose of the stem 70 defining the axis of symmetry of the valve 7 the roughness of the plane 75 must be kept very low for correct operation of the regulator. To obtain a very low roughness surface, the valve 7 must be confined and then the plane 75 must be wrapped. This machining can be done for the largest number of members that can be held by a single fixture.

이 고정구는 그 속에 다수의 보어가 구비되며, 각각이 판면에 수직되게 대칭축을 유지하기 위해 밸브(7)의 스템(70)을 내장할 수 있는 금속판으로 구성된다. 따라서, 평면(75)은 판면에 평행이며 외향하고, 평면(71)은 판면과 접촉한다.The fastener is provided with a plurality of bores therein, each consisting of a metal plate capable of embedding the stem 70 of the valve 7 to maintain an axis of symmetry perpendicular to the plate surface. Therefore, the plane 75 is parallel to the plate surface and outward, and the plane 71 is in contact with the plate surface.

각 보어 내로 그들의 스템(70)을 삽입함으로써 이 판상에 설치된 밸브(7)로 래핑공구는 평면(75) 전체에 걸쳐 구동되고, 견고히 배치된다. 밸브(7)에 대한 제2도에 도시한 형상의 선택은 자동기계에 의한 조정기(1)의 조립을 가능하게 한다. 이것은 보어(75)가 조립의 1단계중 적당한 자동 기계고정구에 의해 밸브(7)가 지지될 수 있게 하기 때문이다.By inserting their stems 70 into each bore, the wrapping tool is driven and firmly placed throughout the plane 75 with the valve 7 installed on this plate. The selection of the shape shown in FIG. 2 for the valve 7 enables the assembly of the regulator 1 by an automatic machine. This is because the bore 75 allows the valve 7 to be supported by a suitable automatic mechanical fixture during one stage of assembly.

이 고정구는 이것을 케이싱(40)에 동축으로 유지하므로 하우징(40)과 지지부재(8) 사이의 동축도(coaxialiey)를 발견할 수 있게 하며, 그 원추대 공동(81)은 밸브(7)의 구면(72)에 의해 지지된다. 따라서 다이어프램(2)은 하우징(40)의 연부(41)에 대해 똑바로 위치하게 된다.This fixture holds it coaxially with the casing 40 so that a coaxialie between the housing 40 and the support member 8 can be found, the cone cavity 81 being the spherical surface of the valve 7. Supported by 72. Thus, the diaphragm 2 is positioned upright with respect to the edge 41 of the housing 40.

스프링(21)의 세팅과 조립을 포함하는 계속되는 동작과 링(9)에 의한 하우징(30)의 조립과 클램핑은 간단한 방법으로 즉시 수행될 수 있다.Continued operation, including the setting and assembly of the spring 21 and the assembly and clamping of the housing 30 by the ring 9 can be performed immediately in a simple manner.
