Abstract (en)
[origin: WO2004040121A1] A fuel supply pump with a large fuel discharge amount and a tappet structure body that are suitably used for a accumulated pressure-type fuel injection device that mechanically intensifies pressure. In a tappet structure body with a pass-through hole and a fuel supply pump with a spring seat, a penetration portion through which a lubricant or a fuel for lubrication passes is provided by cooperation of the tappet structure body and the spring seat. The penetration portion is provided between a spring-holding chamber for holding a spring used when a plunger is pulled down and a cam chamber for receiving a cam for lifting/lowering the plunger.
