Definitions
- the invention is based on one
- Fuel injection device or a pressure booster device according to the preamble of the independent claims. From DE 199 10 970, fuel injection devices or pressure booster devices are already known, in which a pressure booster piston enables the fuel injection pressure to be increased beyond the value provided by a common rail system by means of filling or emptying a rear space.
- pressure booster devices have the advantage that, by means of a valve which, depending on the fuel pressure prevailing in the rear area, connects the side of the pressure booster device connected to the high-pressure fuel source directly to the side connected to the fuel injector, it is possible to both fill the rear area with Fuel as well as locking the side of the pressure translation device connected to the injector from the high-pressure fuel source with this one valve without additional components.
- Another advantage is that the high-pressure chamber of the pressure booster device connected to the fuel injector is not filled via a spring-loaded separate check valve, for example, but via a path that is constantly open in the reset phase. This ensures an improved, in particular faster, resetting of the piston of the pressure transmission device.
- an additional control of the combination valve by the pressure build-up in the high-pressure space is particularly advantageous, so that, in addition to the pressure drop in the rear space, the pressure build-up in the high-pressure space simultaneously drives the valve body and can thus switch the combination valve particularly quickly.
- FIG. 1 shows a fuel injection device
- FIG. 2 shows a pressure booster device in the active state
- FIG. 3 shows the pressure booster device of a further fuel injection device.
- FIG. 1 shows a fuel injection device in which an injector 10 is connected to a high-pressure fuel source 60 via a pressure booster device 30.
- the high-pressure fuel source comprises several elements, not shown, such as a fuel tank, a pump and the high-pressure rail of a common rail system known per se, the pump providing a fuel pressure of up to 1600 bar in the high-pressure rail by injecting fuel from the tank transported the high pressure rail.
- the injector 10 has a fuel injection valve with a valve member 12 which projects with its injection openings 8 into the combustion chamber 11 of a cylinder of an internal combustion engine.
- the valve member is surrounded on a pressure shoulder 9 by a pressure chamber 13, which is connected via a high-pressure line 21 to the high-pressure chamber 40 of the pressure transmission device 30.
- the schematically illustrated valve member protrudes at its end facing away from the combustion chamber into a working chamber 18 which is connected via a throttle 20 to the high-pressure line 21 and via a throttle 19 to a control valve 15 of the injector, the Throttle 20 has a smaller opening cross section than the throttle 19.
- the control valve 15 is designed as a 2/2-way valve and is closed in the first position; in the second position, it connects the throttle 19 to a low-pressure line 17.
- the valve member is resiliently mounted via a return spring 14, the return spring pressing the valve member against the injection openings 8.
- the spring-containing space of the injector injector is connected to a further low-pressure line 16.
- the pressure transmission device 30 has a spring-mounted piston 36 which separates the high-pressure space 40 connected to the high-pressure line 21 from a space 35 which is connected directly to the high-pressure fuel source 60.
- the spring 39 used to support the piston is arranged in a rear space 38 of the pressure transmission device 30.
- the piston 36 has an extension piece 37 which has a smaller diameter than the piston 36 at its end facing the space 35.
- the rear space 38 can be connected to a low-pressure line 32 via a 2/2-way valve 31.
- the low-pressure line 32 like the low-pressure lines 16 and 17, leads back to the fuel tank (not shown).
- the space 35 of the pressure transmission device is connected to the rear space 38 via a throttle 47 integrated as a bore in the piston.
- a combination valve 50 is integrated in a bore 58 of the piston 36.
- the bore communicates with space 35.
- a cylindrical valve body 51 is movably mounted in it.
- a spring 54 is arranged between the piston 36 and the valve body 51, which in the relaxed state presses the valve body just so far in the direction of the space 35 that the valve space 53 on the one hand has an inlet conduit 52 and which leads to the space 35 as a bore in the piston on the other hand, is connected to a high-pressure chamber line 56 leading to the high-pressure chamber 40 and designed as a bore through the extension piece 37.
- valve chamber 53 is also located Regardless of the position of the valve body 51 via a bore hole in the piston 36 and at the end of the bore 58 facing the end of the bore 58 into the bore outlet chamber 55 in connection with the rear chamber 38, since the valve body 51 on its side facing the spring 54 has through the spring center extension 57 which, as shown in Figure 2, limits the movement of the valve body as soon as it has closed the lines 52 and 56.
- the mode of operation of the stroke-controlled injector 10 is known per se from German patent application DE 199 10 970.
- a high fuel pressure is constantly present at the high-pressure line 21.
- Fuel passes from the pressure chamber 13 through the injection openings 8 into the combustion chamber 11 as soon as the valve member at its end facing away from the injection openings is briefly relieved of fuel pressure by opening the 2/2-way valve 15 and thus the opening shoulder acting on the pressure shoulder 9 acting force is greater than the sum of spring force (14) and force due to the remaining in the working space 18
- the pressure of the high-pressure fuel source passes via the inlet line 52 and the high-pressure space line 56 to the high-pressure space 40 and from there to the injector 10 an injection with the pressure of the high-pressure fuel source can take place at any time.
- the control valve 15 of the injector only has to be actuated, as a result of which the injection valve opens. If an injection with increased pressure is now to take place, then the intensifier control valve 31 is opened so that the pressure in the rear space 38 can drop, as a result of which the combination valve 50 closes. In the closed state, the combi valve 50 closes, as shown in FIG. 2, the high pressure chamber line 56 and the inlet line 52.
- the fuel to be compressed in the high pressure chamber 40 cannot flow back (check valve function of the combi valve) and the fuel from the chamber 35 only flows in a throttled manner via the throttle 47 into the rear space 38 (filling valve function of the combination valve).
- the piston 36 is not pressure-balanced and there is a pressure increase in the high-pressure space 40 in accordance with the pressure-area ratio of the space 35 and the high-pressure space 40 Pressure equalization between rooms 35, 38 and 40.
- the combination valve 50 opens when the pressure in the rear room 38 has reached the pressure in the room 35 minus an opening pressure difference.
- the opening pressure difference of the combination valve is determined by the spring constant of the spring 54 and the hydraulic pressure surfaces of the valve body to the spaces 35 and 53. In the illustrated embodiment, the hydraulic pressure areas are the same size.
- Pressure translation device take place. Because the injection can take place at two different pressure levels (rail pressure and translated pressure) and one It is possible to switch on the pressure booster at any time, the injection course can be shaped flexibly. Rectangular, ramp-shaped or "boat" injections with variable length of the boot phase are possible.
- FIG. 3 shows a further embodiment of the fuel injection device according to the invention.
- the pressure transmission device arranged between the high-pressure fuel source 60 and the high-pressure line 21 leading to the injector 10 has a piston 36 with an integrated alternative combination valve 70.
- the valve body 78 of the combination valve 70 is movably mounted in a cylindrical cavity 88 of the piston 36.
- An inlet line 72 designed as a bore in the piston 36 leads from the space 35 into an annular groove 90 of the cavity 88.
- the rear space 38 is connected to the cavity 88 via the rear space line 74, regardless of the position of the valve body in the cavity, so that there is always a prevailing in the rear space Can attack fuel pressure on the valve body.
- a spring 80 is stretched between the wall of the cavity 88 and a shoulder of the valve body 78 in such a way that when forces act predominantly on the valve body in the direction of the spring force, a> liquid exchange between the space 35 and the cavity 88 can take place via the annular groove 90.
- an elevation 94 of the valve body arranged on the end of the valve body facing away from the spring 80 is pressed against the cavity boundary.
- a high-pressure chamber line 76 designed as a bore in the piston connects the high-pressure chamber 40 to the part of the cavity 88 located between the pressure surface 92 delimited by the elevation 94 and the piston wall.
- the combination valve 50 thus has both a pressure surface to the high pressure chamber 40, the pressure surface 92, and a pressure surface to the rear chamber 38, it is closed by a falling pressure in the rear chamber and by an increasing pressure in the high pressure chamber.
- the opening spring force of the spring 80 defines the opening pressure difference between the rear space and the high pressure space up to which the combination valve is open.
- the sealing function is for the high-pressure space line 40 through the flat sealing seat surfaces 82 and for the inlet line 72 through the
