Description
본 발명은 자동차 연료공급계통의 레귤레이터에 관한 것으로서, 특히 레귤레이터의 구성을 개선하여 정밀한 연료압력조절 및 동작중에 발생되는 소음을 저감시키는데 그 목적이 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a regulator of an automotive fuel supply system, and more particularly, to improve the configuration of a regulator and to reduce noise generated during precise fuel pressure regulation and operation.
연료공급계통에서 레귤레이터는 연료가 충진된 연료분배관 내부의 연료충진압력을 일정하게 유지시키는 압력조절장치로 도 1과 같이 연료를 분사하는 인젝터(1)가 구성된 연료분배관(2)의 일단에 구성되어 연료유입구(3)를 통해 연료분배관(2) 내부로 유입된 연료의 충진압력을 조절하고 과도하게 충진된 연료는 연료탱크(미도시)로 귀송시킨다.In the fuel supply system, the regulator is a pressure control device for maintaining a constant fuel filling pressure inside the fuel distribution pipe filled with fuel, and is connected to one end of the fuel distribution pipe 2 including the injector 1 for injecting fuel as shown in FIG. 1. It is configured to adjust the filling pressure of the fuel introduced into the fuel distribution pipe (2) through the fuel inlet (3), and overfilled fuel is sent back to the fuel tank (not shown).
이와 같은 레귤레이터(4)의 구성은 도 2와 같이 연료분배관(2) 내부로 연료가 유입되는 유입구(5)와, 상기 유입구(5)를 통해 유입된 연료의 과다한 충진압력으로 밀려 올려가도록 진동판(6)이 고정된 진동막(7)과, 상기 진동막(7)을 가압하는 탄성부재(8)와, 상기 탄성부재(8)로 가압되는 진동막(7)이 충진연료의 압력으로 밀려올라감에 따라 개방되어 연료탱크로 연료가 귀송되는 배출로(9)가 구성된다.The configuration of the regulator 4 is a diaphragm so as to be pushed up by the excessive inlet filling pressure of the fuel introduced through the inlet port 5, the fuel flows into the fuel distribution pipe 2, as shown in FIG. The vibrating membrane 7 to which the 6 is fixed, the elastic member 8 for pressing the vibrating membrane 7, and the vibrating membrane 7 for pressing the elastic member 8 are pushed by the pressure of the filling fuel. The discharge path 9 is configured to open as it is raised and to return fuel to the fuel tank.
이와 같이 구성되어 연료탱크로부터 연료가 펌핑되어 연료유입구(3)를 통해 연료분배관(2) 내부로 유입되고, 유입된 연료의 충진압력이 과도한 경우 레귤레이터(4)에서 연료의 충진압력을 조절하여 연료탱크로 귀송한다.In this way, the fuel is pumped from the fuel tank and introduced into the fuel distribution pipe 2 through the fuel inlet 3, and when the filling pressure of the introduced fuel is excessive, the regulator 4 controls the filling pressure of the fuel. Return to the fuel tank.
이때, 레귤레이터(4) 내부는 레귤레이터(4)의 유입구(5)를 통해 유입된 연료가 연료분배관(2) 내부의 충진압력값을 고려한 탄성부재(8)의 탄성력으로 가압되고 있는 진동판(6) 및 진동막(7)을 밀어올리고, 연료의 충진압력이 과도하게 상승됨이 따라 진동판(6) 및 진동막(7)이 더욱 밀려올라가 배출로(9)를 개방하여 과충진된 연료를 연료탱크로 귀송하여 연료분배관(2) 내부에 충진된 연료의 충진압력을 조절한다.At this time, the inside of the regulator 4 is a diaphragm 6 in which fuel introduced through the inlet 5 of the regulator 4 is pressed by the elastic force of the elastic member 8 in consideration of the filling pressure value in the fuel distribution pipe 2. ) And the vibrating membrane 7 is pushed up, and as the filling pressure of the fuel is excessively increased, the diaphragm 6 and the vibrating membrane 7 are pushed further, and the discharge passage 9 is opened to release the overfilled fuel tank. Return to the to control the filling pressure of the fuel filled in the fuel distribution pipe (2).
그러나, 이와 같이 구조의 레귤레이터(4)는 연료탱크로부터 펌핑되어 공급되는 연료의 공급압력에 따라 진동판(6) 및 진동막(7)이 상/하 동작중에 레귤레이터(4)의 내부에서 소음을 유발하고 진동판(6) 및 진동막(7)이 전체적인 일자형태로 제작되어 설치됨에 따라 상/하동작이 원할하지 못하여 연료의 충진압력을 정밀하게 조절하지 못하는 문제점이 있다.However, the regulator 4 of this structure causes noise inside the regulator 4 during the up / down operation of the diaphragm 6 and the diaphragm 7 according to the supply pressure of the fuel pumped from the fuel tank. As the diaphragm 6 and the diaphragm 7 are manufactured and installed in the form of an overall straight line, there is a problem in that the up / down operation is not desired and the filling pressure of the fuel cannot be precisely controlled.
본 발명은 상기한 문제점을 감안한 것으로, 레귤레이터에서 연료의 충진압력이 조절된 후 연료분배관으로 연료가 유입되도록 하면서, 레귤레이터 내부에 구성된 진동막의 소음발생을 저감하도록 진동막을 드로잉하여 신축성이 용이한 구조로 개선하고, 엔진이 정지된 후 엔진의 과열열량을 전달받아 연료분배관 내부의 압력이 상승함에 따라 레귤레이터로 역유입되는 연료를 연료탱크를 귀송하도록 탄성부재의 탄성력을 받는 이동편으로 구성된 레귤레이터를 구성하는데 있다.The present invention has been made in view of the above-described problems, and the structure is easy to stretch by drawing the vibration membrane to reduce the noise generation of the vibration membrane configured inside the regulator while the fuel is introduced into the fuel distribution pipe after the filling pressure of the fuel in the regulator is adjusted. After the engine is stopped, the regulator consists of a moving piece receiving elastic force of the elastic member to return fuel back to the fuel tank as the pressure inside the fuel distribution pipe is increased by receiving the superheated heat of the engine. It is in composition.

도 3 및 도 4와 같이 연료분배관(101)에 구성되어 연료분배관(101) 내부로 충진되는 연료의 충진압력을 조절하는 레귤레이터(102)에 있어서, 레귤레이터(102)는 외부케이스인 제 1하우징(103) 및 제 2 하우징(104)과, 상기 제 1,2 하우징(103,104)의 사이에 구성되어 연료의 충진압력으로 상/하 움직이는 진동막(105)과, 상기 진동막(105)에 탄성력을 제공하는 제 1 탄성부재(106)와, 연료공급관(107)과 연결되어 연료를 유입하는 연결구(108)와, 상기 연결구(108)의 일단을 밀봉하는 밀봉체(109)와, 상기 연결구(108)의 내부에서 연료분배관(101)에 유입된 연료의 역유입으로 상/하 움직이는 이동편(110)과, 상기 이동편(110)에 탄성력을 제공하는 제 2 탄성부재(120)와, 상기 제 2 하우징(104) 및 상기 연결구(108)에 결합되어 연료의 누설을 방지하는 오링(130)으로 구성한다.In the regulator 102, which is configured in the fuel distribution pipe 101 and adjusts the filling pressure of the fuel charged into the fuel distribution pipe 101 as shown in FIGS. 3 and 4, the regulator 102 is the first case which is an outer case. Between the housing 103 and the second housing 104, and the first and second housings 103 and 104, the vibrating membrane 105 to move up and down at the filling pressure of the fuel, and the vibrating membrane 105 A first elastic member 106 providing an elastic force, a connector 108 connected with the fuel supply pipe 107 to introduce fuel, a seal 109 sealing one end of the connector 108, and the connector A moving piece 110 moving up and down by reverse flow of fuel introduced into the fuel distribution pipe 101 inside the 108, and a second elastic member 120 providing an elastic force to the moving piece 110. The O-ring 130 is coupled to the second housing 104 and the connector 108 to prevent leakage of fuel.
미설명 부호 140은 제 2 하우징(104)에 결합되어 레귤레이터(102)를 통과한 연료를 연료분배관(101) 내부로 유입하는 캡이다.Reference numeral 140 denotes a cap coupled to the second housing 104 to introduce fuel passing through the regulator 102 into the fuel distribution pipe 101.
이와 같이 구성한 본 발명의 레귤레이터(102)는 연결구(108)에 연결된 연료공급관(107)을 따라 연료탱크로부터 연료가 펌핑되어 레귤레이터(102) 내부로 유입되고, 레귤레이터(102) 내부로 유입된 연료는 연결구(108)와 이동편(110) 사이의 틈을 빠져나오며 밀봉체(109)와 이동편(110)의 사이공간으로 유입되어 제 1 탄성부재(106)의 탄성력으로 가압되는 진동막(105)을 밀어올린다.In the regulator 102 of the present invention configured as described above, the fuel is pumped from the fuel tank along the fuel supply pipe 107 connected to the connector 108 to be introduced into the regulator 102, and the fuel introduced into the regulator 102 is Vibrating membrane 105 that exits the gap between the connector 108 and the moving piece 110 and flows into the space between the sealing member 109 and the moving piece 110 and is pressed by the elastic force of the first elastic member 106. Push it up.
이때, 연료의 충진압력으로 상/하 이동하는 진동막(105)은 유연한 곡선으로 드로잉하여 일체형으로 제작함으로서, 연료의 충진압력에 따라 원할하게 상/하 동작하며 발생되는 소음이 저감된다.At this time, the vibrating membrane 105 that moves up / down by the filling pressure of the fuel is drawn in a flexible curve and manufactured integrally, so that the noise generated by the up / down operation smoothly according to the filling pressure of the fuel is reduced.
이후, 진동막(105)을 가압하는 제 1 탄성부재(106)의 복원력과 평행을 이룰때까지 진동막이 상승하며 연료를 연료분배관(101)으로 유입시키고, 연료분배관(101)에 충진된 연료가 각실린더로 공급되어 소모되면 연료분배관(101) 내부의 압력이 떨어져 제 1 탄성부재(106)의 탄성력을 받고 있는 진동막(105)이 하강하며 연료의 유입이 차단된다.Subsequently, the vibrating membrane rises until the vibrating membrane is parallel with the restoring force of the first elastic member 106 that presses the vibrating membrane 105, injects fuel into the fuel distribution pipe 101, and the fuel filled in the fuel distribution pipe 101. Is supplied to each cylinder and consumed, the pressure inside the fuel distribution pipe 101 drops and the vibrating membrane 105 under the elastic force of the first elastic member 106 descends and the inflow of fuel is blocked.
그리고, 공급되는 연료의 충진압력이 높아짐에 따라 진동막(105)이 다시 밀려올라가며 연료를 연료분배관(101) 내부로 유입한다.Then, as the filling pressure of the supplied fuel is increased, the vibrating membrane 105 is pushed back and the fuel is introduced into the fuel distribution pipe 101.
한편, 엔진이 정지된후 연료분배관(101)의 내부에 충진된 연료가 엔진의 과열열량을 전달받아 연료분배관(101) 내부의 압력이 상승되면 연료분배관(101)에 충진된 연료가 레귤레이터(102)로 역유입 된다.On the other hand, if the fuel filled in the fuel distribution pipe 101 after the engine is stopped receives the superheated heat of the engine and the pressure inside the fuel distribution pipe 101 is increased, the fuel filled in the fuel distribution pipe 101 Back flow into the regulator (102).
레귤레리터(102)로 역유입된 연료는 진동막(105)을 밀어올린후 제 2 탄성부(120)로 가압되는 이동편(110)을 밀어내며 연결구(108)와 이동편(110)의 틈을 통해 연료탱크로 귀송된다.The fuel flowed back into the regulator 102 pushes up the vibrating membrane 105 and then pushes the moving piece 110 pressurized by the second elastic part 120 to connect the connector 108 and the moving piece 110. It is sent back to the fuel tank through the gap.
이상에서 설명한 바와 같이 본 발명의 레귤레이터는 드로잉된 일체형의 진동막을 구성함으로서, 진동막의 상/하 동작을 원할하게 하며 발생되는 소음을 저감하고, 엔진정지후 엔진의 과열열량을 전달받아 압력이 상승된 연료를 레귤레이터에서 조절하여 연료탱크를 귀송하도록 한 발명이다.As described above, the regulator of the present invention constitutes an integrated vibrating membrane, thereby smoothing up / down operation of the diaphragm, reducing noise generated, and receiving an overheated heat amount of the engine after stopping the engine. The invention is to control the fuel in the regulator to return the fuel tank.
