Abstract (en)

[origin: WO0046497A1] A high-pressure fuel pump (24), a high-pressure fuel filter (26) and a fuel pressure regulator (34) are housed, shut off from the atmospheric air, in a case (40) which is corrosion-resisting and rust-resisting against damage from salt water. A position above the oil surface of an oil tank (10) communicates with the atmospheric air via an atmospheric communication pipe (74). A fuel check valve (76) is installed at the portion of the pipe (74) which is closer to the fuel tank (10), and an air check valve (78) at the portion of the pipe which is closer to the atmosphere. A second breathing pipe (82) communicating with the inside of the case (40) is allowed to communicate between the fuel check valve (76) position and the air check valve (78) position on the pipe (74). Therefore, the inside of the case (40) does not communicate directly with the atmosphere, but communicates only with the pipe (74) communicating with the atmosphere (on the downstream side of an air cleaner in an engine intake path (75)) and the fuel tank (10), thereby preventing the rusting of high-pressure fuel parts, such as the high-pressure fuel pump (24), the high-pressure fuel filter (26) and the fuel pressure regulator (34) due to shut off atmosphere.
