    摘要： A pump for low-viscosity fuel comprises a pump shaft 6 installed in a pump housing 2, 3, 4 and divided into a drive-side shaft 6A and a driven-side shaft 6B, a partition 12 provided between the drive-side shaft and the driven-side shaft of the pump shaft to prevent leakage of fuel from the housing, and a magnetic coupling 13 for transferring torque from the drive-side shaft to the driven-side shaft of the pump shaft through the partition, the magnetic coupling being disposed such that a first clearance C1, D1 between the magnetic coupling and the partition is larger than a second clearance C2, D2 between the magnetic coupling and the pump housing. When wobble occurs in the pump shaft owing to wear of the sliding contact portions thereof, the magnetic coupling makes contact with the pump housing before contacting the partition, thereby enabling the rotation of the pump shaft to be stopped before fuel leakage occurs.

    摘要： A radial piston pump for low-viscosity fuel according to a first aspect of the invention comprises a pump housing, which is constituted of as few as two structural bodies (from among a drive-side housing member 2A, a fixed cylinder 81 and a cover 4), and a leaf valve member 82 which is formed with intake valves 87 for opening and closing intake side passages 27 and discharge valves 88 for opening and closing discharge side passages 28 and is sandwiched between two structural bodies (fixed cylinder 81 and cover 4). The first aspect of the invention reduces the number of components constituting the pump housing, enables highly precise overall axial alignment, prevents wobbling of a pump shaft 9 of the pump, increases performance and reliability and reduces cost. A radial piston pump for low-viscosity fuel according to a second aspect of the invention comprises a leaf valve member 205 formed in one and the same plane thereof with overflow ports communicating with an overflow passage 59 in the pump housing, intake valves 87 communicating with intake side passages 27 and discharge valves 88 communicating with discharge side passages 28. The third aspect of the invention provides a method for assembling the radial piston pump for low-viscosity fuel according to the second aspect of the invention.

    摘要： A fuel injection device for a diesel engine or the like confines the fuel injection pressure to a predetermined range. Fuel is fed under pressure from a fuel supply source to a high pressure chamber to develop a pressure therein. An injection nozzle is mounted on a nozzle holder and has a nozzle hole for injection fuel in response to the pressure in the high pressure chamber. The nozzle holder has thereinside a low pressure chamber which communicates to the outside. An injection rate control valve is mounted in the nozzle holder for delivering fuel to the low pressure chamber on the elevation of the fuel pressure communicated to the high pressure chamber beyond a predetermined value.

    摘要： Three way valves forming a fuel cut-off valve are arranged across respective injection pipes connected to injection nozzles associated with preselected cylinders of the engine. In a first valve position, the three way valves connect the injection pump body or bodies of the fuel injection pump to the respective injection pipes, and in a second valve position, they connect the injection pump body or bodies to a lower pressure zone in the pump. Preferably, the fuel cut-off valve is pneumatically operated for high speed valve position changing action.
