  • Publication number: 20050106049
    Abstract: A fuel supply pump with a large fuel discharge amount and a tappet structure body, which are suitably used for an accumulated pressure-type fuel injection device that mechanically amplifies pressure, is provided. A fuel supply pump has a tappet structural body and a spring sheet, wherein a penetration portion for allowing passage of a lubricant or a fuel for lubrication therethrough by coordinating the tappet structure and the spring sheet is provided between a spring-holding chamber for holding a spring to be used for pulling up a plunger and a cam chamber for housing a cam to be used for moving the plunger up and down.

  • Publication number: 20050106035
    Abstract: A high flow rate fuel valve suitable for an accumulator fuel injection device by which a large amount of fuel is amplified using a piston and used and a fuel supply pump using the high flow rate fuel valve are provided. For this purpose, in a fuel supply pump with a fuel inlet valve and fuel outlet valve, the fuel inlet valve has a valve main body, a valve body received in the valve main body, an inlet chamber provided inside the valve main body, inlet holes, a seat portion where the valve body and part of valve main body are in contact with each other. The inlet holes are arranged in a non-radial pattern relative to the inlet chamber.

  • Patent number: 6771600
    Abstract: A packet insertion interval control system includes a counting unit (32), having a first bit field for managing an insertion interval of a management packet required to be cyclically inserted and a second bit field for specifying a logic path for forwarding the management packet, for executing such a counting operation as to periodically cycle the first bit field and the second bit field, and a control unit (31) for executing control for specifying, when a count value indicated by the first bit field of the counting unit is a predetermined value, the logic path for forwarding the management packet on the basis of a count value indicated by the second bit field of the counting unit, and for inserting the management packet into the specified logic path. With this architecture, it is feasible to restrain an increase in quantity of the hardware and flexibly correspond to changes in the number of connections (number of channels) and the cell insertion interval (packet insertion interval) per communication system.
