종래의 연료공급장치는 도 1과 같이 연료가 주입된 연료통(1) 내부의 격통(2)에 구성된 연료펌프(3)와, 상기 펌프(3)에서 펌핑된 연료가 송출관(4)을 따라 압송되며 연료에 혼합된 이물질을 여과하는 여과필터(5)와, 상기 여과필터(5)에서 여과되어 엔진(6)의 각실린더(미도시)로 공급되기 전에 송출된 연료가 충진되는 연료분배관(7)과, 상기 연료분배관(7)에 충진되는 연료의 충진압력을 조절하는 충진압력조절장치(8)와, 상기 충진압력조절장치(8)의 조절에 따라 연료분배관(7)으로 충진되는 연료가 과도하면 연료통(1)으로 귀송시키는 바이패스배브(9)가 구성된다.The conventional fuel supply apparatus has a fuel pump 3 configured in the barrel 2 inside the fuel container 1 into which fuel is injected as shown in FIG. 1, and the fuel pumped from the pump 3 follows the discharge pipe 4. Filtration filter 5 for filtering the foreign matter mixed with the fuel and fuel, and a fuel distribution pipe filled with the fuel sent out before being filtered by the filtration filter 5 and supplied to each cylinder (not shown) of the engine 6 (7), the filling pressure adjusting device (8) for adjusting the filling pressure of the fuel filled in the fuel distribution pipe (7), and the fuel distribution pipe (7) in accordance with the control of the filling pressure control device (8) When the fuel to be filled is excessive, a bypass barb 9 configured to return to the fuel container 1 is configured.

이와 같이 구성된 종래의 연료공급장치는 연료통(1)에 주입된 연료를 연료펌프(3)에서 펌핑하여 송출관(4)을 따라 압송하고, 압송과정에서 송출관(4)상에 구성된 여과필터(5)에서 연료에 혼합된 이물질이 여과되어 연료분배관(7)에 충진된다.In the conventional fuel supply device configured as described above, the fuel injected into the fuel container 1 is pumped by the fuel pump 3 to be pumped along the delivery pipe 4, and the filtration filter configured on the delivery pipe 4 in the transporting process ( In 5), foreign matter mixed with the fuel is filtered and filled in the fuel distribution pipe (7).

한편, 연료분배관(7)에 충진되는 연료는 엔진(6)의 각실린더로 공급되기 전에 충진압력조절장치(8)에서 압력이 조절되고, 과도하게 연료가 충진되면 충진압력조절장치(8)에서 이를 차단하여 연료펌프(3)에서 연속적으로 펌핑되어 공급되는 연료를 바이패스밸브(9)를 통해 연료통(1)으로 되돌려 보내는 싸이클로 순환되며 엔진(6)으로 연료를 공급한다.On the other hand, the fuel charged in the fuel distribution pipe (7) is adjusted in the pressure in the filling pressure regulating device (8) before being supplied to each cylinder of the engine (6), the filling pressure regulating device (8) if excessive fuel is filled Blocking this from the fuel pump 3 is continuously pumped from the fuel pump 3 is supplied to the engine (6) is circulated to the cycle to send back to the fuel container (1) through the bypass valve (9).
