<P>PROBLEM TO BE SOLVED: To provide a fuel feeder capable of being mounted even in a high-temperature atmosphere by reducing the number of components of the fuel feeder and setting a surplus fuel passage in the fuel feeder. <P>SOLUTION: This fuel feeder includes: a body including an intake port, an ejection port, and a discharge port; an intake filter arranged in the intake port; a cylinder arranged in the body; a piston slidably fitted to the cylinder; a swash plate; motor for rotating the swash plate; and a pressure regulating device incorporated in the cylinder; and is structured to return a part of a surplus fuel ejected from the pressure regulating device to an intake side on the downstream side of the intake filter. In the fuel feeder, a passage for returning a part of the surplus fuel ejected from the pressure regulating device to the intake side on the downstream side of the intake filter is formed with an annular part formed between a nearly cylindrical bush fitted to the cylinder and the motor, and the body, and a returning flow rate is adjusted by an annular clearance amount of the annular part. <P>COPYRIGHT: (C)2013,JPO&INPIT |
