摘要： An electronically controlled fuel injection device includes a plunger pump, a circulation passage which circulates fuel that has been pressurized in the initial stage of a pressure-feeding stroke, a valve body which blocks the circulation passage in the later stage of the pressure-feeding stroke, an inlet orifice nozzle which allows the passage of fuel whose pressure has been increased in the later stage of the pressure-feeding stroke, an outlet orifice nozzle which is used to circulate some of the fuel that has passed through the inlet orifice nozzle back into the fuel tank, an injection nozzle which injects an amount of fuel equal to the difference between the fuel that has passed through the inlet orifice nozzle and the fuel that has passed through the outlet orifice nozzle, and a control arrangement for controlling the plunger pump in response to the cycle of the engine.

摘要： An electronically controlled fuel injection device includes a plunger pump constituted by a cylinder, a plunger is slidably mounted within the cylinder to form a pressure chamber, and a solenoid coil for driving the plunger. At a lower section of a body that encases the plunger pump, an intake section is coupled to the pressure chamber to cause intake of fuel into the pressure chamber upon operation of the plunger. At an upper section of the body, a return section is arranged to return surplus fuel to a fuel tank. A circulation passage branches off from the intake section and is provided between the cylinder and the solenoid coil for guiding a portion of the fuel toward the return section. With this arrangement, penetration of vapor into the fuel injection device is suppressed, and an inexpensive and highly durable electronically controlled fuel injection device is provided.

摘要： An internal combustion engine fuel supply system includes a fuel discharge apparatus having a vapor removal system. The fuel discharge apparatus includes an apparatus body, a fuel chamber defined in the body, a fuel inlet connected to a fuel tank, a fuel supply path partially defined by the fuel inlet and connecting the fuel chamber to the fuel tank, a fuel discharge outlet, a fuel return outlet for return of excess fuel to the fuel tank, and a reflux path connecting the fuel supply path to the fuel return outlet. A vapor blocking member is provided in the fuel supply path at a bifurcation point at which the reflux path branches from the fuel supply path. The reflux path is arranged such that vapor blocked by the vapor blocking member rises from the bifurcation point and through the reflux path to the fuel return outlet due to self-buoyancy of the vapor.

摘要： In a fuel injection system, a fuel tank is disposed below an electronically controlled fuel injection apparatus. A fuel reservoir chamber for supplying fuel from the fuel tank is disposed above the electronically controlled fuel injection apparatus, and the fuel stored in the fuel reservoir chamber is supplied to the electronically controlled fuel injection apparatus via a fuel supply passage. The fuel reservoir chamber and the fuel tank are connected by a first fuel return passage through which vapor is ejected and fuel in the fuel reservoir chamber overflows. A second fuel return passage for returning surplus fuel from the electronically controlled fuel injection apparatus is connected to either of the fuel reservoir chamber and the first fuel return passage at the position above the connecting position at which the fuel reservoir chamber connects with the first fuel return passage.

摘要： [Problem] To reduce the size, lower the cost and increase and flatten the thrust of an electromagnetic actuator in which a plunger moves reciprocally.[Solution] The electromagnetic actuator comprises a yoke 130, a coil 180 arranged around the yoke, an armature 120 slidably arranged inside the yoke and integrally formed with a plunger 110, and a return spring 150 for returning the armature to a rest position, wherein the yoke 130 has, in a predetermined position on the axial direction L, a thickness-reduced annular gap groove 133 over part of an outer peripheral face 131, the thickness-reduced portion having a trapezoidal cross section widening outwards. Such a constitution allows shortening the magnetic path, allows increasing and flattening the electromagnetic force (thrust) generated for the displacement of the armature, allows increasing the acceleration (responsiveness) of the armature, and allows, for instance, reducing the parts count, simplifying assembly operations, and achieving cost reductions, while requiring no high-precision control of assembly positions.
