Definitions

  • a fuel injection device for an air-compressing, self-igniting internal combustion engine is known (DE-OS 29 03 482), in which an electromagnetically actuable control valve is provided within the injection pump housing to control the injection times, which controls the suction channel of the injection pump on the one hand and an outflow channel with a on the other High pressure channel of the injection pump connects.
  • the control valve has a valve body designed as a piston slide, which is provided with a valve seat, a high-pressure chamber and a low-pressure chamber being provided on both sides of the valve seat in the piston slide.
  • the housing space of the control valve is preferably sealed pressure-tight outside the high-pressure side connections and has a high-pressure side and a low-pressure side housing space chamber which are assigned to the end faces of the spool, the high-pressure side and the low-pressure side housing space chamber by at least one line, which is preferably provided by a line inside the spool Hole is made, are connected to each other.
  • a fuel injection device in cross section.
  • the fuel injection device is provided in the usual way with a fuel injection pump 1, which consists of a pump housing 2, a pump element 3 designed as a pump piston, which can be moved in a known manner via a cam 4 and a spring-loaded tappet 5 in a pump chamber 6, an intake duct 7 and a high-pressure duct 8.
  • the fuel is supplied to the pump work chamber 6 of the fuel injection pump 1 via a suction channel 7 from a fuel feed pump, not shown, and is conveyed to a fuel injection nozzle 10 via a high-pressure channel 8 during the stroke of the pump piston 3 through the high-pressure channel 8.
  • the high-pressure channel 8 is controlled by an electromagnetic control valve 11, which has a valve body designed as a piston slide 12 and loaded by a compression spring 13, which is operatively connected in the opening direction to an electromagnetic actuating device 14. Via the electromagnetic control valve 11, the high-pressure channel 8 is in the open position of the control valve 11 with, for example, a fuel tank leading outflow channel 15 connectable, so that by opening or closing the electromagnetic control valve 11 in the high pressure phase of the fuel injection pump 1, the start of injection or the end of injection of the fuel injector 10 can be regulated.
  • the opening movement of the piston slide 12 is limited by a spacer 27, which, like the compression spring 13, is arranged in the high-pressure-side housing space chamber 20, the spacer 27, the compression spring 13 and the electromagnetic actuating device 14 in order to generate a resulting pressure closing force on the end faces of the Piston slide 12 are provided or the end faces of the piston slide 12 are designed such that the end face area of the piston slide 12 exposed to the high-pressure side chamber pressure is larger than the end face area of the piston slide 12 which is exposed to the low pressure side chamber pressure.
  • the pump piston 3 has a longitudinal groove 42 in its outer surface, which is in flow connection with the pump work chamber 6 and can be brought into alignment with the suction channel 7 by rotating the pump piston 3.
  • a mechanical control device (not shown in more detail) is provided, which works with generally known means, for example centrifugal weights etc., as a function of the speed and, at a predeterminable maximum speed of the internal combustion engine, releases the connection between the pump work chamber 6 and the intake duct 7 for the purpose of controlling fuel . This measure serves as an additional safety device.
  • the first switching coil 29 with the associated armature 31 and the iron core 30 and the second switching coil 34 with the associated armature parts 35a and 35b and the second iron core 36 are assigned to the low-pressure-side housing space chamber 21 and provided with corresponding sealing elements 24, the inner armature part 35a of the second switching coil 34 acts directly on the spool 12 and the armature 31 of the first Switching coil 29 is in direct operative connection with the inner armature part 35a of the second switching coil 34.
  • the switching coil 29 and the switching coil 34 are controlled as a function of the control times of the electromagnetic control valve 11 determined by the electrically operating control device.
  • the first switching coil 29 is energized and the second switching coil 34 is de-energized during the closed position of the spool 12, so that the spring element 32 is maximally pretensioned and the outer armature part 35b bears against the stop element 38 and there is a preliminary stroke distance between the inner armature part 35a and armature 33 .
  • the closing movement of the piston slide 12 is initiated by switching off the second switching coil 34, so that the compression spring 13 brings the piston slide 12 into the closed position, although in this case advantageously only the armature parts 35a and 35b need to be carried along.
  • This inventive design of the electromagnetic actuating device 14 advantageously makes it possible to keep the magnetic actuating forces to be applied and thus the construction volume claimed low due to the predominant holding function of the first switching coil 29 and the second switching coil 34.
  • a sensor device 40 In the area of movement of the low-pressure end face of the piston valve 17, a sensor device 40 is provided, which - not shown in detail - has a permanent magnet, pole shoes and an induction coil and, depending on the piston valve movement or an air gap between the piston valve face and the inner one Anchor generates 35a a pulse-shaped signal in the M eßwert Norways worn as Schierzeittician- or the control valve opening time signal can be evaluated and can be taken into account when driving the switching coils 29 and 34 to prevent magnetic transmission errors corresponding, although the local arrangement of the sensor device shown 40 is not mandatory, but also preferably the one or a second sensor device 40 between the armature 31 and the outer and inner armature parts 35a and 35b can be provided according to the invention.
  • Fig. 4 is of similar design as the embodiment according to FIG. 3, but the first switch coil 29, the iron core 30 and the armature chaltspule 31 of nie uman professionen housing space chamber 21 and the second S 34 and the armature inner member 35, the armature outer member 35b and the iron core 36 are assigned to the housing chamber 20 on the high-pressure side, again suitable sealing elements 24 being provided for the pressure-tight sealing of the housing chambers 20, 21.
  • the armature 31 of the first switching coil 29 is in direct operative connection with the spool 12 and the inner armature part 35a is attached directly to the spool.
  • the spacing element 33 is designed in this embodiment such that in the closed position of the spool 12, the armature 31 can be moved by an excitation of the first switching coil 29 into an axial distance from the spool 12 is.
  • the iron core 36 has a shoulder 36a designed as a spacer element, which interacts with the inner anchor parts 35a.
  • a fastening member 49 is screwed onto the thread of the connection bore 48, which is in operative connection with the pressing elements 47 and connects the holding element 52 pressure-tightly to the fuel injection pump 1 and thus to the pump chamber 6 via these pressing elements 47.
  • a receptacle 51 for the pressure valve 9 is provided facing away from the fuel injection pump and is designed in an analogous manner to the receiving bore 48 of the fuel injection pump 1. It should be noted that the bore 43 of the holding element 52 is made with a slight oversize, in order to avoid any deformation or tensioning of the sealing gaps 28a and 28b on the low-pressure and high-pressure side resulting from the fastening of the pressure valve 9 in the receiving space 51.
