Document Type and Number:
Japanese Patent JP2009236006
Kind Code:
A
Abstract:

To obtain a fuel supply device which can control noise at the discharge of surplus fuel from a pressure regulator while realizing miniaturization.

The fuel supply device includes a flange, a fuel pump, a high-pressure filter, and the pressure regulator. The high-pressure filter is internally provided to the first space which is formed by a filter case and a filter cover. The filter case is integrally molded with the flange, and the pump holder retaining the fuel pump and the pressure regulator is inserted and attached to the filter cover. A return channel which enables the fuel filtered by the high-pressure filter to reach the pressure regulator is formed in the second space formed by the flange and the filter cover. Then the axes of the return channel on the flange side and the filter-cover side are not brought into agreement with each other. Furthermore, a partitioning plate which is parallel with the axis of the return channel is provided on the flange side of the second space.
