Definitions
- a fuel injector with a pressure-balanced control valve in the axial direction is known.
- the control valve has an adjustable by means of an electromagnetic actuator in the axial direction between a closed position and an open position control sleeve which is guided on a, passing through the control sleeve guide pin.
- the guide pin is formed integrally with a valve body on which the control valve seat is arranged for the control sleeve.
- control valve seat is expensive to manufacture due to its poor accessibility and that a comparatively large minimum diameter of the guide pin for strength reasons must not be exceeded, since the supply of fuel from a control chamber via a provided in the valve body Outflow channel is performed, which is cut perpendicularly within the guide pin of transverse bores.
- the invention is based on the idea of selecting the cone angle of the external truncated-cone-shaped control valve seat so that the stop slip of the sealing surface region of the control sleeve is minimized relative to the control valve seat or, in the optimum case, completely avoided.
- the cone angle of the control valve seat is selected from a value range between about 120 ° and about 170 °, a positive effect with respect to minimizing the stop slip across the length of the control sleeve results.
- This effect can be attributed to the fact that a cone angle of a value range between about 120 ° and about 170 °, depending on the dimensions and geometric design of the sealing surface having sealing surface.
- a radially outwardly acting force component is induced in the sealing region of the control sleeve, which counteracts the Nachinneng faced the sealing area, as this is observed in a flat seat, counteracts.
- a cone angle of 120 ° is not exceeded, it is achieved that the induced, radially outwardly acting force component is lower than in a conical control valve seat with a cone angle of 90 °, whereby, a (too large) radially outwardly acting, elastic deformation or movement of the control sleeve in its sealing area relative to the control valve seat is surprisingly avoided.
- cone angle in the sense of the invention means the angle enclosed by two lateral surface sections (oblique sections) of the control valve seat located in a plane receiving the longitudinal central axis of the control valve seat.
- the cone angle is the doubled angle between the lateral surface of the outer truncated cone-shaped control valve seat and the longitudinal center axis of the control valve seat.
- control sleeve in which in the control sleeve only one on one of which the control erventilsitz having valve body, spaced component ab 100 pin is provided and the control sleeve is guided on its outer circumference.
- control sleeve alternatively by means of a piezo actuator or an electromagnetic actuator between its closed position in which it rests on the control valve seat and a spaced from the control valve seat opening position in which the control chamber is hydraulically connected to a low pressure region of the injector, is adjustable.
- an optimum cone angle of the control valve seat for the specific application has to be selected from the value range between approximately 120 ° and approximately 170 °. It has been found that cone angles from a value range between 130 ° and 170 ° are to be preferred. Especially preferred are cone angles from a value range between 140 ° and 170 °. In tests, particularly good results were achieved in the combination of a seat diameter (sealing diameter) of 2.5 mm and a cone angle of 140 °.
- a cone angle from a range of values between 150 ° and 170 °, preferably from a range of values between 155 ° and 160 ° has been found.
- a cone angle of the control valve seat of 160 ° is optimal.
- an embodiment is advantageous in which the inner cone angle of the inner surface of the sealing surface (something) is greater than the cone angle of the outer frustum-shaped control valve seat.
- the angular difference between the inner cone angle and the portion of the control sleeve having the sealing surface is selected from a value range between approximately 1 ° and approximately 10 °.
- Particularly preferred is an inner cone angle greater by about 2 ° to 9 ° than the cone angle of the control valve seat.
- Particularly optimized results with regard to the wear and tightness of the control valve in the closed state were achieved with an angle difference between the inner cone angle and the cone angle of the control valve seat from a value range between 3 ° and 6 °.
- control valve as a pressure balanced in the axial direction valve, ie a valve on the control sleeve act in the closed state no directed in the axial direction, resulting adjustment forces.
- This can be realized in particular by the fact that the sealing surface frontally adjacent to the inner peripheral wall of the control sleeve and extending from this in the radial direction outwards and in the axial direction, ie in the direction of the control valve seat.
- the seat line with which the control sleeve interacts with the outer truncated cone-shaped control valve seat adjoins the inner circumference of the control sleeve.
- the inner diameter of the sealing line corresponds to the inner diameter of the control sleeve.
- an embodiment in which connects to the sealing surface having sealing area in the radial direction of an annular surface, preferably in an imaginary, transverse to the longitudinal extension of the control sleeve Ebe - ne is. It is within the scope of the development that this, the maximum extent of the sealing surface limiting annular surface with the transversely extending to the longitudinal extent of the control sleeve, imaginary plane includes an angle from a value range between about -20 ° and about + 20 °.
- the invention also leads to a fuel injector for injecting fuel into a combustion chamber of an internal combustion engine.
- This has a designed according to the concept of the invention, preferably in the axial direction pressure-balanced control valve with a control sleeve which cooperates with an outer truncated cone-shaped control valve seat having a cone angle from a value range between 120 ° and 170 °.
- control valve By opening the control valve, ie by lifting the control sleeve from the Steuerven- tilsitz operatively connected to a one-piece or multi-part injection valve element control chamber is connected to an injector return, so that the fuel pressure in the control chamber drops rapidly and the injection valve element lifts from its valve seat and fuel through at least one nozzle hole opening can flow into the combustion chamber of the internal combustion engine.
- the control sleeve is operatively connected to an anchor plate, ie integrally with this is formed or, in particular form-fitting, connected thereto, wherein the armature plate cooperates for adjusting the control sleeve with an electromagnetic actuator.
