Title:
FUEL LUBRICATION DEVICE FOR INJECTION PUMP
Document Type and Number:
Japanese Patent JP2010090797
Kind Code:
A
Abstract:

To provide a fuel lubrication device for an injection pump enabling the installation lengths of large-diameter pipes to be reduced and the drive power of a feed pump to be minimized.

In this fuel lubrication device for an injection pump, the fuel in a fuel tank 1 is fed, through a fuel feed passage 2, to an accumulating fuel injection device 8 with a common rail 6 and an injector 7 through the feed pump 3 and the injection pump 5 formed of a high-pressure pump 4. The fuel at the outlet of the feed pump 3 is taken out through a flow control valve 10 to lubricate the sliding parts 3a, 4a of the feed pump 3 and the high-pressure pump 4. A circulation flow passage 17 for returning the fuel to a fuel feed flow passage 2 at the inlet of the feed pump 3 after lubricating the sliding parts 3a, 4a of the feed pump 3 and the high-pressure pump 4 is provided to form a fuel circulation loop 18.
