  • Injection injectors of the type described above are often used in common rail injection systems.
  • Injectors for common rail systems for injecting high viscosity fuels into the combustion chamber of internal combustion engines are known in various forms. In the case of heavy oil, heating up to 150 ° C is required to achieve the necessary injection viscosity. With a high proportion of abrasive solids and a high temperature naturally increases the Veschl employ and thus affects the reliability.
  • an injector for a common rail injection system has different parts, which are usually held together by a nozzle retaining nut.
  • the actual injector nozzle contains a nozzle needle, which is guided axially displaceably in the nozzle body of the injector nozzle and has a plurality of open spaces through which fuel can flow from the nozzle antechamber to the needle tip.
  • the nozzle needle itself carries a collar on which a compression spring is supported, and dives into a control room, which can be acted upon with fuel under pressure.
  • An inlet channel can be connected to this control chamber via an inlet throttle and an outlet channel via an outlet throttle, wherein the respective pressure built up in the control chamber together with the force of the compression spring holds the nozzle needle in the closed position.
  • the pressure in the control chamber can be controlled by a control valve, which is usually operated by an electromagnet.
  • a control valve which is usually operated by an electromagnet.
  • an opening of the solenoid valve can cause a flow of fuel through a throttle, so that a decrease in the hydraulic holding force leads to the immersed into the control chamber end face of the nozzle needle for opening the nozzle needle. In this way, the fuel can pass through the injection openings in the combustion chamber of the engine in the sequence.
  • an inlet throttle is usually also provided, wherein the opening speed of the nozzle needle is determined by the flow difference between the inlet and outlet throttle.

  • a heating of the valve for example, before the engine start, possible.
  • the flushing quantity is supplied to the control valve in the region of the valve seat of the valve member.
  • the purge quantity diverted between the feed pump and the high-pressure pump mixes directly at the input of the control valve with the fuel coming from the supply or discharge channel, so that essentially the entire control valve is traversed by the already cooled fuel.
  • the armature chamber of the control valve is flown through by the flushing quantity, so that in particular the part of the solenoid valve subject to a strong thermal load can be efficiently cooled.
  • the control of the cooling power is carried out in a particularly preferred manner in that the diverted between the prefeed pump and the high-pressure pump purge amount, preferably by means of a throttle or a purge valve, is regulated.
  • the regulation can advantageously be carried out as a function of measured values of a temperature sensor, wherein the temperature sensor detects the temperature of the magnetic valve or of the fuel in the outlet of the magnetic valve. In this way, a particularly simple temperature control.
  • the procedure is preferably such that the fuel from the prefeed pump is pressurized to 5. 10 bar is promoted.
  • the present invention also aims to provide a device for injecting fuel into the combustion chamber of an internal combustion engine, in which an improved cooling of the solenoid valve is achieved.
  • the device comprises a prefeed pump for conveying fuel from a tank, a high-pressure pump and an injection injector, wherein the fuel delivered by the prefeed pump of the high pressure pump and the high pressure fuel delivered by the high pressure pump is supplied to the injector, the injector having an injector with an axially displaceable nozzle needle which is immersed in a controllable with fuel under pressure control chamber whose pressure is controllable via a at least one inlet or outlet channel for fuel opening or closing control valve.
  • the device is essentially characterized in that between the prefeed pump and the high-pressure pump, a branch line is connected, which is connected to a flushing channel of the injection injector, wherein the flushing channel opens on the control valve, so that the flushing amount flows through the control valve at least partially and preferably with the fuel from the inlet and outlet channel mixed, and that the branch line via a heat exchanger (31) is guided for controlling the temperature of the flushing.
