摘要： A fuel injection system includes a pressure chamber. The pressure chamber has a displaceable piston (24), which can be subjected to pressure via a low-pressure-side pressure booster chamber, for compressing the fuel in a high-pressure-side pressure booster chamber to be delivered to an injector. The stroke of the piston (24) is controllable essentially by the pressure in a differential chamber of the pressure chamber and is used to vary the fuel pressure delivered to the injector. Means (24, 25) for enlarging the cross section of the outlet cross section out of the differential chamber of the pressure chamber are provided. The fuel pressure during the injection can be varied. A pressure increase can be achieved with simple means.

摘要： An object of the present invention is to provide an accumulator fuel injection system comprising a pressure increasing unit 7 and a pressure increasing common rail 6, in which leaked fuel is recirculated from a high pressure side to a low pressure side, and which is capable of reducing the amount of fuel that must be delivered under pressure by a low pressure pump 3. The focus of the present invention is to return high pressure leaked fuel to between the low pressure pump 3 and a high pressure pump 5. The accumulator fuel injection system of the present invention comprises the low pressure pump 3 for delivering fuel under pressure from a fuel tank 2, the high pressure pump 5 for changing the fuel from the low pressure pump 3 into high pressure fuel, an accumulator (common rail) 6 for accumulating the high pressure fuel from the high pressure pump 5 at a predetermined pressure, an injector 8 which is connected to the accumulator 6 for injecting the high pressure fuel, and the pressure increasing unit 7 which is provided between the injector 8 and the accumulator 6 for further increasing the pressure of the high pressure fuel. Leaked fuel from the pressure increasing unit 7 may be recirculated to the downstream side of the low pressure pump 3 through a unit leakage passage 17.

摘要： A fuel injection system for internal combustion engines, has a distributor tube and a high-pressure pump which is driven as a function of engine rpm and serves to generate the fuel pressure and fuel throughput required in the distributor tube in the applicable operating state of the engine, and also has a fuel metering unit, which is assigned to the high-pressure pump and is based on an electromagnetically actuated regulating valve. The fuel metering unit is disposed in the high-pressure pump, and the outlet of the regulating value discharges into the low-pressure region of the high-pressure pump. The inlet of the regulating valve communicates with the compression side of a prefeed pump. The regulating valve has a valve piston, which is actuated—into the opening position—by a compression spring and which is actuatable counter to the spring force—into the closing position—by an armature bolt of the electromagnet. Valve piston has at least one and preferably more radial control openings, which are in operative communication with the intake side of the high-pressure pump.

摘要： The invention relates to a control unit for an injection system for fuel, having a control part movable between a valve seat and a stop face of a bore in the housing. A high-pressure line discharges into a bore that penetrates the housing and receives the control part. A control face of the control part opposite the valve seat acts in the higher rpm range as a throttle element for filling a pump chamber in the housing.

摘要： In a flow amount control device which control flow amount of fuel to be supplied to a high pressure fuel pump, an opening, which communicates with a port for passing fuel to the high pressure fuel pump, is composed of a first rectangular opening, a second rectangular opening whose circumferential length is larger than that of the first opening, and a third trapezoidal opening bridging between the first and second openings. The port communicates with the first opening, when engine speed is low, and, as the engine speed increases, with the third and second openings. Accordingly, the flow amount of fuel to be discharged from the high pressure fuel pump varies non-linearly and a change of the flow amount thereof is small in engine low speed region.
