摘要： Each of the pump cylinders disposed in a line, of the fuel injection pump is surrounded in the vicinity of an overflow opening controlled by control edges of the pump piston by a partial suction chamber embodied as a hollow space. Each of these partial suction chambers is supplied with fuel, beginning at an inflow conduit via a throttled inflow opening and the fuel is carried away again via a return-flow opening into a return-flow conduit common to all the pump cylinders. Because of the crosswise flushing of each individual partial suction chamber the fuel temperature in these partial suction chambers is kept at least virtually constant, in order that identical fuel quantities will be supplied to the individual pump cylinders.

摘要： A control device for Diesel engines is proposed in which a rapid shutoff of the engine can be effected by evacuating the suction chamber of the injection pump. The control device includes a supply pump and a reversal valve, which in a stop position connects the suction chamber with the intake side of the supply pump and connects the compression side of the supply pump with the fuel tank. A check valve is provided in the supply line between the supply pump and the fuel filter which, when closed, is vacuum-tight; this check valve is disposed to open toward the filter, counter to the force of a valve closing spring. Another check valve, comprising an overflow valve determining the suction chamber pressure, is provided in an overflow line leading from the suction chamber to the fuel tank; this overflow valve is also vacuum-tight when closed. When the reversal valve is actuated by an electromagnet, a similar key-actuated shutoff to that known in gasoline engines can also be effected in Diesel engines. The circuitry of this embodiment also enables an involuntary "rolling start" to be blocked, and allows for a fail-safe shutoff of the engine in case of a malfunction in the governor shutoff device.

摘要： A fuel injection pump for internal combustion engines having a plurality of pump elements disposed in a row, the onset and end of supply of each being effected by means of a respective control slide that is axially displaceable on the pump piston and by the control of relief conduits for the pump work chamber. The control slides are actuated via a rotary shaft; upon rotation of the rotary shaft, the control slides are axially displaced via driver arms secured on the rotary shaft. To adjust the axial position of the individual control slides relative to one another, the driver arms are permanently deformed in the axial direction of the control slides.

摘要： A fuel injection pump for internal combustion engines having at least one pump element comprising a housing, a cylinder liner in the housing, a pump piston operative in the cylinder liner, a recess in the cylinder liner having a radial entrance, for a control slide which controls injection onset during axial displacement on the pump piston. In the vicinity of the entrance to the recess which discharges into the pump work chamber, an apron is disposed on the control slide or on the cylinder liner, in order to cover a portion of a radial three-dimensional gap present between the control slide and the cylinder liner. By this means, the diverted fuel stream that is reflected by the side walls can be interrupted and reflected at least one additional time, so as thereby to reduce its kinetic energy.

摘要： A fuel injector having a piezoelectric actuator. A needle valve is mounted in the injector body and has an opening hydraulic surface substantially surrounded by a high-pressure fuel line in fluid communication with a high-pressure fuel chamber. A control piston partly defines a piston control chamber, which is in fluid communication with the opening hydraulic surface and the high-pressure fuel chamber. The piezoelectric actuator is activated between an off position and an on position for positioning a control valve into an open position or a closed position. A high-pressure fuel condition is maintained in the piston control chamber by fuel supplied from the high-pressure fuel chamber and independent of any actuation of the control valve. In a low pressure fuel condition, a force on the opening hydraulic surface of the needle valve member is greater than the downward force on the closing hydraulic surface thereby opening the needle valve member for producing an injection event.
