Definitions
- the invention relates to a fuel injection device according to the preamble of patent claim 1.
- Such a fuel injection device is, for example, by the DE 100 44 120 A known.
- the aforementioned DE 100 44 120 A discloses a fuel injector including an injector, a high pressure fuel injecting line to the injector under high pressure, and a pilot valve controlling the pressure in a control chamber of the injector connected to the high pressure line, the movable valve member of which is actuatable by an actuator via a hydraulic coupler having two a piston of the coupler having cooperating pistons, wherein the seat of the movable valve member having a clear cross-sectional area f3, wherein the pistons are arranged parallel to each other, wherein the outer piston is mechanically coupled with a piston surface f4 to the actuator via a rod with a cross-sectional area f5 , and wherein the inner piston, which has a piston surface f2, actuates the control valve via a rod with a smaller cross-sectional area f1 than f2.
- the associated hydraulic chambers are connected via a compensation chamber to the leakage line, ie at low pressure. Low pressure acts on the inner piston in the second hydraulic chamber and high
- a control valve is known in which the direction of closing movement of a movable valve member coincides with the direction of fuel flowing out of a control chamber, so that the control valve is at least partially force balanced because of the high pressure on the second piston.
- the fuel injection device according to the invention for internal combustion engines with the characterizing features of claim 1 has the opposite advantage that a CR injector is provided with piezoelectric actuator, in which a large valve cross-section is possible. As a result, the opening and closing of the injection valve can be done faster.
- the integrated coupler allows a short overall length of the device. The coupler is supported by CR printing.
- FIG. 1 An embodiment of the fuel injection device according to the invention is shown in the drawing and will be explained in more detail in the following description. It shows the single figure the essential components of a fuel injection device according to the invention with an injection valve and a control valve and a hydraulic coupler.
- the fuel injection device 1 is supplied from a pressure accumulator (common rail) 3 with fuel at high pressure via a high-pressure line 5, from which fuel passes via an injection line 6 to an injection valve 9.
- An internal combustion engine normally has a plurality of such injectors, and for the sake of simplicity only one is shown.
- the injection valve 9 has a valve needle (valve piston, nozzle needle) 11, which closes with a conical valve sealing surface 12 in its closed position injection openings 13, is to be injected through the fuel into the interior of a combustion chamber of the internal combustion engine.
- the fuel enters the area of the nozzle needle via an annular nozzle chamber 14, from which it allows to exert a pressure in the opening direction of the nozzle needle via a control surface 15 formed as a pressure shoulder. When said pressure exerts a force in the opening direction on the valve needle, which overcomes this opening counteracting forces, so the valve opens.
- An actuator 31 serves to control the opening and closing of the injection openings. It generates a deflection and a force for actuating further elements as a function of an activation at a mechanical output.
- it is an electrically actuated actuator.
- it is an actuator which has a piezoelectric element, namely a piezoelectric actuator.
- the actuator assumes a lengthy configuration or a shortened configuration depending on an electrical drive in the vertical direction of the drawing and thus in its longitudinal direction.
- an actuator is provided with such a construction, which assumes a patentede configuration when energized (connected to a DC power supply), without energization occupies a shortened configuration.
- the actuator forms a capacitive load and absorbs no power loss during continuous power.
- the piezoelectric actuator by a clamping device, for. As spring so pretension that contained in the actuator piezoelectric elements are always subjected to pressure. This is known to those skilled in the art and therefore will not be referred to hereinafter. While the upper end of the piezoelectric actuator is anchored in the injection device in a manner not visible in the drawing, the lower end of the piezoelectric actuator is used to ultimately use its force and movement to open and close the injection ports.
- a hydraulic coupler 38 is provided for its coupling, which has a piston 39 coupled to the piezoelectric actuator and a further piston 40. In the present application is generally by the coupler, an enlargement of the path of the further piston 40 in comparison to the path of the piston 39 (by appropriate choice of the hydraulically effective piston surfaces) necessary. The construction and operation of the hydraulic coupler will be described below.
- the sink If the not directly connected to the piezoelectric actuator piston 40 of the hydraulic coupler opens a control valve 41 (or exhaust valve), the sinks Pressure in a fuel-filled control chamber 43, in which engages the upper end portion of the nozzle needle.
- the control chamber 43 is filled with fuel under pressure via an inlet throttle 47, and when the control valve 41 is open, fuel flows out of the control chamber 43 via an outlet throttle 49.
- the outflow of fuel is assisted by forces that tend to move the nozzle needle 11 to its open position.
- a movable valve piece 51 sealingly abuts a valve seat 53 when the control valve 41 is closed and is mechanically coupled to the piston 40.
- the outflowing with the valve piece 51 open from the control chamber control amount is discharged through a leakage channel 55.
- the pistons 39 and 40 are in the example parallel to each other and into each other, manufacturing technology advantageous coaxial with each other (integrated coupler). The way in which they are coupled together is explained below.
- an arrow is shown, which indicates the movement of this piston when the actuator performs a movement in the drawing down.
- an arrow is shown, which indicates the movement of this piston when the piston 39 carries out the movement indicated by its arrow.
- the movable valve piece 51 is formed substantially conically with a cylindrical extension. In particular, it rests against the valve seat 53 with the conical part in the closed state.
- the valve piece 51 is biased by a guided by the cylindrical extension compression spring 54 in the direction of its valve seat 53. In its blocking position, it has been moved "out", namely in the direction of high pressure in the control chamber 43 to a region of lower pressure (leakage pressure).
- the exhaust valve is therefore referred to in this case as an A-valve.
- the valve seat 53 facing side of the Valve piece 51 is rigidly connected to an actuating part which is connected to the hydraulic coupler.
- the connection with the piston 37 is advantageous tensile strength for a particularly fast closing.
- the actuator 31 is connected to the piston 39 by a rod 61 having a diameter d5.
- the piston 40 is connected to the movable valve member 51 to be actuated by a rod 63 having a diameter d1.
- the outer piston 39 has an annular piston surface with an area size f4, the inner piston 40 has a diameter d2 (and therefore an area size 0.25 x ⁇ x d2 2 ).
- the clear diameter of the valve seat 53 where the movable valve member abuts against it is d3.
- Guide gaps 65 and 67 which serve to slide the pistons and through which a coupler volume is filled with fuel, are formed in the area of the outer cylindrical surface of the outer piston (opposite to a housing, not shown) and in the area of mutual sliding of the two pistons.
- the other end region of the inner piston 40 projects into a filling space 71-2, which is filled with CR pressure via an annular groove 71 'via a channel 71 "in the piston 39.
- the booster chamber 72 is filled 72 is penetrated by the rod 63.
- the filling space 71-1 is penetrated by the rod 61.
- the pistons 39 and 40 move in opposite directions and because of the desired path ratio from the actuator to the control valve at different speeds.
- CR pressure pressure of the pressure accumulator or common rail
- the valve member 51 is closed by the pressure in the booster chamber 72 with a proportional to (d2 2 - d1 2 ) force.
- the filling space 71-2 is filled with CR pressure, as a result of which the seat diameter d3 of the valve part 51 can be selected to be very large, since the piston 40 largely compensates for this surface with its rear side located in the filling space 71-2.
- the invention provides an advantageous A-valve servo-injector with CR pressure assist for very fast opening and closing of the injector.
- the coupler ensures a short overall length.
- An important feature of the invention is that at the rear (as opposed to the side of the booster chamber) of the piston directly connected to the control valve 40 rail pressure is applied, which supports the actuation of the control valve and the valve member 51 in the locked state of the control chamber 43rd counteracts acting pressure.
- the force to be supplied by the actuator for closing the valve is therefore smaller than the known one.
- a valve 51 is provided with a larger diameter d3 than the known one, which permits faster opening and closing allows the injection valve, because the flow increase and decrease in this is greater than in the known smaller A-valve.
- a compression spring 75 in the filling chamber 71-2 pushes the pistons apart and ensures good contact of the coupler on the actuator 31 and with the valve closed 51 of the valve seat 53.
- the invention also covers embodiments in which the high pressure fuel is not supplied by a high pressure accumulator but by a pump (e.g., unit injector) associated with the injector which also feeds the charge space.
- a pump e.g., unit injector
