PROBLEM TO BE SOLVED: To obtain a high pressure fuel supplying device which can reduce pulsative pressure of the fuel without increasing the size, and attain improvement of durability. SOLUTION: This high pressure supplying device 200 has followings. A high pressure fuel pump 6 which pressurizes fuel supplied from a low pressure fuel suctioning passage 3 and discharges it to a high pressure fuel discharging passage 7 as high pressure fuel. A high pressure damper 8 which is arranged on the high pressure fuel discharging passage 7 for absorbing pulsative motion of the high pressure fuel. A high pressure regulator 10 which is arranged on a branch passage 9 branched from a branch portion 18 of the high pressure fuel discharging passage 7, for adjusting the pressure of the high pressure fuel from the high pressure damper 8 to a specified pressure. An orifice 60 which is arranged on the high pressure fuel discharging passage 7 on the downstream side of the branch portion 18, for absorbing pulsative motion of the high pressure fuel. |
