Abstract:
The pump housing includes a pair of sliding surfaces clamping the outer and inner gears from both their sides to allow both the gears to slide on the sliding surfaces, a suction port part suctioning fuel from outside into inside of the gear accommodation chamber, and a discharge port part discharging fuel from inside into outside of the gear accommodation chamber. At least one of the suction port part and the discharge port part includes an elongated groove that is depressed from the corresponding sliding surface and extends along a circumferential direction of the pump housing in a region opposed to the pump chambers, opening bores that open on the elongated groove from outside of the gear accommodation chamber, and ribs each of which is arranged between the corresponding adjacent two opening bores. The opening bores and the ribs are arranged alternately along an extending direction of the elongated groove.

Claim (Index 1):
A fuel pump comprising:\n an outer gear that includes a plurality of internal teeth; an inner gear that includes a plurality of external teeth and is eccentric relative to the outer gear in an eccentric direction to be engaged with the outer gear; and a pump housing that defines a gear accommodation chamber, which rotatably accommodates the outer gear and the inner gear, wherein: the outer gear and the inner gear expand and contract volumes of a plurality of pump chambers formed between both the gears, and rotate to suction fuel into the gear accommodation chamber and then discharge fuel from the gear accommodation chamber; the pump housing includes:\n a pair of sliding surfaces that clamp the outer gear and the inner gear from both their sides to allow both the gears to slide on the pair of sliding surfaces; \n a suction port part that suctions fuel from outside into inside of the gear accommodation chamber; and \n a discharge port part that discharges fuel from the inside into the outside of the gear accommodation chamber; \n at least one of the suction port part and the discharge port part includes:\n an elongated groove that is depressed from a corresponding one of the pair of sliding surfaces and extends along a circumferential direction of the pump housing in a region opposed to the plurality of pump chambers; \n a plurality of opening bores that open on the elongated groove from the outside of the gear accommodation chamber; and \n a plurality of ribs each of which is arranged between corresponding adjacent two of the plurality of opening bores; and \n the plurality of opening bores and the plurality of ribs are arranged alternately along an extending direction of the elongated groove.
