  • Publication number: 20060169251
    Abstract: A fuel filter is located downstream of a feed pump to filter fuel discharged from the feed pump. An orifice is located between the fuel filter and a suction quantity control valve to restrict a flow rate of the fuel passing through the fuel filter. A positive pressure of the feed pump is applied to the fuel filter, and a passing pressure at the fuel filter increases. Even if viscosity of the fuel increases and the fuel becomes wax-like at low temperature, clogging of the fuel filter or an insufficient flow rate can be inhibited. The orifice restricts the flow rate of the fuel passing through the fuel filter. Accordingly, an increase in size of the fuel filter can be prevented even if the fuel filter is located downstream of the feed pump.

  • Patent number: 6848429
    Abstract: In a fuel injection pump, a helical gear is attached to an end of a camshaft and rotatable with the camshaft. The camshaft is biased in one axial direction thereof by a driving force that the helical gear receives from an engine crankshaft. A disk is provided in a position of the camshaft extending forward from a cam to the direction in which the camshaft is biased. An axial movement of the disk is restricted via a washer by an end of a bearing cover. The disk is formed in the same axis to a portion of the camshaft that is held by a journal bearing. An outer diameter of the disk is larger than that of the cam. An area where the disk and the washer are in sliding contact with each other is relatively large and the sliding regions thereof are constant so that hammer noises are prevented and frictional wear thereof are limited.

  • Patent number: 6817838
    Abstract: In a fuel injection pump, a casing fixed to a housing has a pump room and a filter room mostly separated from but partly communicating with the pump room. A feed pump is constituted by the pump room where a feed pump mechanism is connected to an axial end of the drive shaft. A filter element is accommodated in the filter room. A casing cover easily attachable and detachable to the casing has a fuel inlet port through which fuel is sucked to the filter room and, then, flows via the filter element into the pump room where the fuel is pressurized according to rotation of the drive shaft. Accordingly, foreign material contained in fuel is eliminated before entering the pump room. Further, fuel flow area of the fuel element is larger than that of the fuel inlet port, resulting in less pressure loss of fuel passing through the filter element even if mesh size of filter element is smaller.

  • Publication number: 20040213689
    Abstract: A rotation-to-linear motion transforming mechanism equipped with a safeguard is provided. The mechanism includes an eccentric cam coupled to a torque input shaft, a cam ring placed in contact of an inner wall thereof with the eccentric cam, and a plunger placed to be movable linearly following rotation of the cam ring. The safeguard is provided in the cam ring which is responsive to application of an excessive torque to the cam ring to break the cam ring, thereby interrupting transmission of torque to the plunger from the torque input shaft. This avoids breakage of the plunger or the whole of the rotation-to-linear motion transforming mechanism. A fuel injection pump equipped with such a safeguard is also provided.

  • Publication number: 20040208753
    Abstract: A low-pressure fuel supplying system (5), a fuel supply control system (6) and a high-pressure fuel discharging system (3) are independently provided as separate pieces, and the low-pressure fuel supplying system (5), the fuel supply control system (7) and the high-pressure fuel discharging system (3) are connected by a fuel pipe. As the high-pressure fuel discharging system (3) is small, relative to a fuel injection pump, it is easier to provide a space for mounting the high-pressure fuel discharging system (3) in the vicinity of the engine. On the other hand, as the low-pressure fuel supplying system (5) and the fuel supply control system (7) have no restriction regarding mounting position, they can be mounted in any empty space in an engine room. Accordingly, the high-pressure fuel supplying apparatus has enhanced mountability on a vehicle.
