Document Type and Number:
WIPO Patent Application WO/2017/199466
Kind Code:
A1
Abstract:
Provided is a fuel distribution device 1 comprising: a fuel distribution pipe 3 that distributes and supplies fuel to a plurality of fuel injection devices 2; fuel piping 4 connected to the fuel distribution pipe 3; and a connection member 5 that connects the fuel distribution pipe 3 and the fuel piping 4. The fuel distribution pipe 3 comprises a seat section 21, on the outer peripheral surface of which a first convexly curved surface 24 that decreases in diameter in a convexly curved surface shape towards the tip on the fuel piping 4 side is formed. The fuel piping 4 comprises a seal section 27, on the inner peripheral surface of which a second concavely curved surface 28 that increases in diameter in a concavely curved surface shape towards the tip on the fuel distribution pipe 3 side and with which the first convexly curved surface 24 is in contact is formed and on the outer peripheral surface of which a second convexly curved surface 29 corresponding to the second concavely curved surface 28 is formed. The connection member 5 presses a seal section 27 against the seat section 21 from the side opposite the fuel distribution pipe 3. The radius of curvature SR2 of the second concavely curved surface 28 is greater than the radius of curvature SR1 of the first convexly curved surface 24.
