Definitions
- the invention relates to a fuel injection device according to the preamble of patent claim 1.
- Integrated couplers with pistons arranged coaxially one inside the other are also known.
- the known device uses an A valve as a control valve. This can only be designed with a relatively small diameter, since otherwise the forces on the valve become too high, so that it cannot be actuated by a piezo actuator.
- the fuel injection device according to the invention for internal combustion engines with the characterizing features of patent claim 1 has the advantage over the fact that a CR injector with a piezo studio is created in which a large cross section of the valve is possible. This allows the injection valve to open and close more quickly.
- the integrated coupler enables a short overall length of the device. The coupler is supported by CR printing.
- the fuel injection device 1 is powered by a pressure accumulator (common rail) 3 with fuel under high pressure
- High-pressure line 5 is supplied, from which fuel reaches an injection valve 9 via an injection line 6.
- An internal combustion engine normally has several such injection valves, and only one is shown for the sake of simplicity.
- the injection valve 9 has a valve needle (valve piston, nozzle needle) 11, which in its closed position closes injection openings 13 through a conical valve sealing surface 12, through which fuel is to be injected into the interior of a combustion chamber of the internal combustion engine.
- the fuel reaches the area of the nozzle needle via an annular nozzle chamber 14, from which it allows pressure to be exerted in the opening direction of the nozzle needle via a control surface 15 designed as a pressure shoulder.
- An actuator 31 is used to control the opening and closing of the injection openings.
- This actuator generates a deflection and a force for actuating further elements as a function of activation at a mechanical output.
- it is an electrically operated actuator.
- it is an actuator that has a piezoelectric element, namely a piezo actuator. The actuator takes an elongated depending on an electrical control in the vertical direction of the drawing and thus in its longitudinal direction
- an actuator with such a construction which takes on an elongated configuration when energized (connection to a DC power supply), and assumes a shortened configuration without energization.
- the actuator forms a capacitive load and does not take up any power loss in the case of constant current
- a tensioning device e.g. B. spring, so that the piezoelectric elements contained in the actuator are always subjected to pressure. This is known to the experts and is therefore not referred to in the following.
- a hydraulic coupler 38 is provided for its coupling, which has a piston 39 coupled to the piezo actuator and a further piston 40.
- the travel of the further piston 40 is generally required to be increased by the coupler in comparison to the travel of the piston 39 (by suitable selection of the hydraulically effective piston surfaces). The construction and operation of the hydraulic coupler is described below.
- the pistons 39 and 40 are arranged parallel to one another and one inside the other, advantageously in terms of production technology, coaxially one inside the other (integrated coupler). The way in which they are coupled is explained below.
- An arrow is drawn in the piston 39, which indicates the movement of this piston when the actuator makes a downward movement in the drawing.
- An arrow is drawn in the piston 40, which indicates the movement of this piston when the piston 39 executes the movement indicated by its arrow.
- the movable valve piece 51 is essentially conical with a cylindrical extension. In particular, it rests on the valve seat 53 with the conical part in the closed state.
- the valve piece 51 is biased in the direction of its valve seat 53 by a compression spring 54 guided by the cylindrical extension. In its locked position, it has been moved "outwards", namely in the direction from the high pressure in the control chamber 43 to an area of lower pressure (leakage pressure).
- the outlet valve is therefore referred to as the A valve.
- the side of the valve piece 51 facing the valve seat 53 is rigidly connected to an actuating part which is connected to the hydraulic coupler.
- the connection with the piston 37 is advantageously tensile for particularly quick closing.
- the actuator 31 is connected to the piston 39 by a rod 61 with a diameter d5.
- the piston 40 is connected to the movable valve part 51 to be actuated by a rod 63 with a diameter d1.
- the inner piston 39 has a diameter d4, the outer piston 40 has an annular piston surface of size f2.
- the clear diameter of the valve seat 53 where the movable valve part rests 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 region of the cylindrical outer surface of the outer piston (in relation to a housing (not shown)) and in the region of the mutual sliding guide of the two pistons.
- the areas f1, f3 to f5 corresponding to the above-mentioned diameters d1, d3 to d5 (for circular cross-sections) and the named area f2 are decisive for the function. Circular cross sections are expedient for the production, but the invention is not restricted to this.
- the end regions of the pistons 39 and 40 facing the actuator 31 engage in a common translator space 72.
- the other end region of the piston 39 engages in a filling space 71-2; this is connected via bores in the lower end wall of the piston 40, which is connected to the line 5.
- the other end region of the inner piston 40 projects into the filling space 71-2.
- the translator room 72 is filled.
- the translator room 72 is penetrated by the rod 61.
- the filling space 71-1 is penetrated by the rod 63.
- the pistons 39 and 40 move in opposite directions and at different speeds because of the desired path translation from the actuator to the control valve.
- the control valve 41 which is an A valve
- the valve part 51 For quick closing of the valve part 51, this is preferably firmly connected to the rod 63 and thus to the piston 40. Because of the CR pressure in the booster space 72, the seat diameter d3 of the valve part 51 can be selected to be very large, since the piston 40 largely compensates for this area with its side located in the booster space 72.
- the invention thus creates an advantageous A-valve servo injector with CR pressure support for very quick opening and closing of the injection valve.
- the coupler ensures a short overall length.
- An important feature of the invention is that rail pressure is present on the side of the piston 39 (in the booster chamber) which faces away from the control valve, which assists the actuation of the control valve and the pressure acting on the valve part 51 from the control chamber 43 in the blocked state counteracts.
- Control valve the valve being an A valve.
- the force to be supplied by the actuator to close the valve is therefore smaller compared to the known one.
- a valve 51 is provided with a larger diameter d3 than the known one, which enables the injection valve to open and close more quickly because the flow increase and decrease therein is greater than in the known smaller A valve.
- a compression spring 75 in the filling chamber 71-2 presses the pistons apart and ensures that the coupler is in good contact with the actuator 31 and, when the valve is closed, the valve part 51 with the valve seat 53.
- the device shown has further features. At least in a region of the rod 61 connecting the actuator 31 to the hydraulic coupler there is a further filling space 90, which is connected to the line 5, at a distance from the space of the coupler closest to the actuator 31.
- the further filling space 90 surrounds the actuator 31 in its lower one
- a guide gap 94 of the rod 61 is dimensioned for an additional filling of the adjacent space of the coupler with fuel under pressure.
- One advantage is the additional filling of the coupler with fuel under high pressure.
- the further filling space 90 is not present or is not connected to the line 5 and does not have the function of a filling space. In this case it may be appropriate to drill a hole in which the Rod 61 is guided in a housing, not shown, of the entire device, for the smallest possible outflow of fuel from the coupler.
- the invention also encompasses embodiments in which the fuel under high pressure is not supplied by a high-pressure accumulator, but by a pump assigned to the injection valve (e.g. pump-injector unit, unit injector), which also feeds the filling chamber.
- a pump assigned to the injection valve e.g. pump-injector unit, unit injector
