Definitions
- the invention relates to a fuel injector according to the preamble of claim 1.
- Diesel common rail systems including fuel injectors or their components are subject to high pressure loads during operation.
- the amount of pressure corresponds approximately to the injection pressures to be achieved in the engine.
- these pressures should be increased as much as possible.
- previous designs have reached their limits in their geometry design.
- leakage is discharged from the holding body via a leakage oil return line which extends in the holding body and opens into a separate low-pressure side space of the holding body, as recordable in DE 100 52 604 A disclosed.
- a fuel injector which has a channel extending in the valve piece, which connects the control chamber with the low-pressure region.
- DE10312913A1 discloses a fuel injector for internal combustion engines, with a nozzle body in an axially displaceable guided nozzle needle, which releases at least one injection hole for fuel injection or closes, with a axially displaceably guided in a holding body valve piston which controls the opening and closing movement of the nozzle needle, with a valve piece in which an auxiliary piston delimits a control space connected to a high pressure side, which is connected via a control valve to a low pressure side, and with a leakage oil return line which discharges leak oil from the area between the auxiliary piston and the valve piston, wherein the leakage oil return line at least partially in the valve piece runs.
- the auxiliary piston is mechanically coupled to the valve piston to actuate the latter.
- the fuel injector for internal combustion engines according to the invention with the characterizing features of claim 1 is used to increase pressure, cost reduction and quality improvement. It can be eliminated by the invention strength-reducing manufacturing process on the holding body.
- the burr formation due to the current construction in the region of the intersection of the leak oil pocket / leak oil groove is eliminated. This eliminates the operation of deburring, and eliminates several operations. Wall thickness problems are solved so that e.g. a longer and more robust valve tightening screw (more carrying aisles) can be used to tighten the holding body, which in turn allows for pressure increases.
- the construction of the invention simplifies the structure of the fuel injector and reduces the number of processing steps.
- an increase in the strength of the holding body and a pressure increase of the fuel injector are possible.
- the in Fig. 1 shown fuel injector 1 is arranged in a pressurized high pressure injection line 2 of the fuel and protrudes into the combustion chamber of the engine to be supplied.
- a piston-shaped valve member (nozzle needle) 5 is slidably mounted with a conical valve sealing surface 6 , which is pressed by a closing spring 7 against a conical valve seat 8 of the nozzle body 4 and closes the injection holes 9 provided there.
- the injection line 2 opens into the nozzle body 4 in an annular pressure chamber 10, from which an annular gap extending between the guide bore 3 and the nozzle needle 5 leads to the valve seat surface 8.
- the nozzle needle 5 has in the region of the pressure chamber 10 designed as a pressure shoulder control surface 11 to which the supplied via the injection line 2 fuel attacks in the opening direction of the nozzle needle 5.
- valve piston 12 which is axially displaceably guided in a guide bore 13 of a holding body 14 and with its one end on the valve sealing surface 6 facing away from the end face of the nozzle needle 5 acts axially.
- Fig. 2 shows limited at the other end of the valve piston 12 with a force acting in the closing direction control surface 15 in a valve member 16 a control chamber 17 which is connected via a Z-throttle 18 to the injection line 2.
- A-throttle 19 From the control chamber 17 is an A-throttle 19 , which is connected via a formed, for example, as a 2/2-way solenoid valve control valve 20 (valve closure member 21 ) with a low-pressure-side Ab Kunststoffraum 22 .
- a leakage oil return line 23 in the form of an axial through hole, which goes off from the low-pressure loaded guide bore 13 of the holding body 14 and extends into the discharge chamber 22.
- the holding body 14 can be made with a greater wall thickness, so that, for example, a longer and more robust valve clamping screw 24 (more carrying gears) can be used for clamping the valve member 16, which in turn allows pressure increases.
- the control surfaces 11, 14 and the closing spring 7 are designed so that when the control valve 20 is closed, i. at the same pressure in the pressure chamber 10 and in the control chamber 17, the nozzle needle 5, the injection holes 9 closes.
- the Z-throttle 18 is smaller than the A-throttle 19, so that by opening the control valve 20 of the pressure prevailing in the control chamber 17 pressure is reduced via the Abêtraum 22 and the pressure prevailing in the pressure chamber 10 pressure is sufficient, the nozzle needle 5 against the effect of Aufzu juryn closing spring 7.
