摘要： A fuel supply apparatus capable of reducing the abrasion of a driving cam and a tappet without increasing the dimensions and weight of the apparatus. This fuel supply apparatus is provided with a tappet which has a pressure receiving surface contacting the driving cam of an engine. The tappet is provided at the part of a outer surface thereof which is in the vicinity of an outer circumference of the pressure receiving surface with a groove adapted to prevent the local concentration of stress on the tappet and having a V-shaped, semicircular or U-shaped cross section.

摘要： A variable delivery type fuel supply apparatus capable of suppressing variation of fuel pressure within a delivery pipe and hence variation of fuel quantity injected through fuel injection valves and simplifying a control method therefor. The apparatus includes an oil relief passage (6) provided between the suction port of a fuel pump (4) and a pressurizing chamber (4e) across a suction valve (4a) of the fuel pump (4), an electromagnetic valve (7) disposed in the oil relief passage (6) and opened for a predetermined time during a discharge stroke of the fuel pump (4) for thereby controlling a discharge quantity of the fuel pump (4), and a control unit (108) for controlling the timing at which the electromagnetic valve (7) is opened. The control unit (108) is so designed as to control open/close operations of the electromagnetic valve (7) such that a time point for starting electrical energization of the electromagnetic valve (7) is fixedly set at a predetermined time point relative to the suction/discharge stroke of the fuel pump (4) while allowing the time point for terminating the electrical energization to be variable, to thereby control the discharge quantity of the fuel pump (4).

摘要： An electromagnetic valve is constructed such that lengths of sealing portions, formed by a housing 8 and a spool valve 7 respectively between an input port 8a and a feed-back chamber 11 and between the feed-back chamber 11 and a core 4, are unchanged upon movement of the spool valve; and aligning grooves 15a and 15b are respectively formed between the input port 8a and the feed-back chamber 11 and between the feed-back chamber 11 and the core 4, whereby a smooth and stable pressure is constantly obtainable in response to an applied current even though a supplied pressure is high.
