Definitions
- the invention relates to a fuel injector according to the preamble of the main claim.
- a fuel injector is known from DE 195 34 445 C2, which has an axially movable nozzle needle in a nozzle body, which is actuated by a piezoelectric actuator and is held by a compression spring in • closed position.
- the fuel is supplied from an external source with freely adjustable pressure.
- the nozzle needle has a 'central bore, wherein the actuator surrounds the Düsennade ⁇ concentrically and is sealed against the fuel pressure by means of sealing surfaces.
- the fuel injection valve according to the invention with the characterizing features of the main claim has the advantage that the structural design of the valve needle allows relief of the actuator by pressure compensation of the valve needle.
- the valve needle experiences in the closed state of the
- Fuel injection valve in the axial direction no pressure force component. This relieves the actuator.
- the zero force of the valve needle can be brought about in that the valve needle is connected to a flexible seal and the connection point with the flexible seal is at the same radial distance from the central axis of the fuel injector as the sealing seat.
- a throttle gap is formed between the valve needle and a valve needle guide, which intercepts the dynamic portion of the pressure. As a result, pressure vibrations no longer reach the corrugated pipe seal.
- a throttle point formed between an annular valve needle guide and the housing of the fuel injection valve ensures that pressure vibrations cannot be transmitted to the valve needle by the fuel flowing through the fuel injection valve.
- the actuator is also free of mechanical pressure loads from the fuel.
- Actively connected actuators are axially guided and thereby offsets of the valve needle and
- Fig. 1 shows a schematic section through an embodiment of a fuel injector designed according to the invention.
- a first exemplary embodiment of a fuel injection valve 1 according to the invention shown in FIG. 1 is in the form of a fuel injection valve 1 for
- Fuel injection systems made by mixture-compressing, spark-ignited internal combustion engines are particularly suitable for injecting fuel directly into a combustion chamber (not shown) of an internal combustion engine.
- the fuel injector 1 comprises a housing 2, in which an actuator 3 is arranged.
- the actuator 3 consists, for example, of several layers 4, which consist of a piezoelectrically excitable material and are glued together, for example.
- the actuator 3 is supported on the inlet side on a housing component 5 and on the downstream side on an actuator head 6.
- valve needle 10 On the downstream side of the actuator head 6 is a valve needle. 10 arranged. Between the actuator head 6 and the valve needle 10 an air gap 11 is formed. The valve needle 10 passes through the intermediate component 9, the valve needle 10 with the intermediate component 9 being sealed via a flexible seal 12, preferably a flexible corrugated tube seal 12, against the fuel flowing through the fuel injection valve 1.
- the corrugated tube seal 12 is with the
- the valve needle 10 passes through the intermediate component 9, which is provided, for example, with a U-shaped cross section, such that an outflow-side leg 14 of the intermediate component 9 serves as a valve needle guide.
- the valve needle 10 can have a recess 15, for example, for reasons of better switching dynamics.
- An actuating body 16 is arranged on the outflow side of the valve needle 10 and has a valve closing body 17 on its outflow end.
- the valve closing body 17 interacts with a valve seat surface 28 to form a sealing seat 25.
- the valve seat surface 28 can in particular be formed on a ring-shaped valve seat body 18, which is either made in one piece with the housing 2 or is connected to it in a suitable manner.
- a return spring 20 is arranged * which keeps the fuel injector 1 closed in the non-polluted state of the actuator 3.
- the fuel injector 1 further comprises a valve needle guide 21, which may be carried out, for example, annular, and whose radial extension is chosen such that a restrictor 22 is formed between the annular valve needle guide 21 and the housing '. 2
- the fuel flowing through the fuel injection valve 1 is supplied via a fuel supply (not shown) and via a fuel line 23, which runs for example in the housing 2, is guided past the actuator 3.
- a fuel supply not shown
- a fuel line 23 which runs for example in the housing 2
- an interior space 24 of the fuel injection valve 1 ′ is completely filled with fuel.
- This fuel is under fuel pressure, the so-called system pressure.
- the fact that the fuel can only throttle the throttling point 22 and thus pass under a considerably lower pressure means that, on the one hand, pressure vibrations cannot reach the corrugated tube 12 and thus the actuator 3 remains unaffected by pressure vibrations, and on the other hand that the mechanical load on the Valve needle 10 and the actuating body 16 remains small due to the fuel pressure and therefore no resonance vibrations can be built up by pressure vibrations.
- the piezoelectric layers 4 expand, so that the actuator foot 6 ' moves in the direction of the valve needle 10 in an outflow direction of the fuel.
- the air gap 11 between the actuator base 6 and the valve needle 10 is thereby .gov ⁇ ⁇ .
- the actuator 3 presses the valve needle 10 and thus also the actuating body 16 in the outflow direction of the fuel, so that the valve closing body 17 formed on the actuating body 16 lifts off the valve seat surface 28 which is formed on the valve seat body 18.
- the fuel injection valve 1 is opened and fuel is sprayed into the combustion chamber of the internal combustion engine, which is not shown in detail.
- connection point 26 at which the valve needle 10 is connected to the flexible seal 12, which is preferably designed as a corrugated tube seal 12, has the same radial distance ' from " the "" central axis "" 27 ⁇ of the fuel injector 1 as the sealing seat 25, then the valve needle 10 is not applied in the closed state by the fuel pressure and • is a result of the valve needle 10 no forces are transmitted to the actuator 3 thus even with a closed air gap 11, pressure balanced.
- the invention is not limited to the exemplary embodiment shown and can also be used, for example, for fuel injectors 1 or magnetostrictive actuators 3 that open inwards.
