    VALVE FOR INFLATING GAS
    The invention relates to a valve for blowing in gas according to claim 1.
    For natural gas vehicles, gas is generally stored in bottles with pressures of up to 200 bar. For this reason, a pressure reducer is required, which reduces the gas from the high pressure to a low rail pressure at the inlet of the valves. The valves are designed, for example, as solenoid valves which, depending on the feed, release the gas into a combustion chamber of the combustion engine.
    The object of the invention is to provide an improved gas blowing valve.
    The object of the invention is achieved by the valve according to claim 1.
    Further advantageous embodiments of the valve are indicated in the dependent claims.
    The valve according to the invention has the advantage that the valve can be activated with low magnet forces. An adjusting element and a closing element are provided for this purpose, wherein the adjusting element has a small distance from the magnet coil in the closing position. The adjusting element is in working connection with the closing element, such that when the magnet coil is supplied, the adjusting element moves the closing element in the direction of the magnetic coil. Moreover, the magnetic element of the magnetic coil causes the closing element to be drawn closer to the magnetic coil independently of the movement of the adjusting element to an open position. By providing the adjusting element and the closing element, it is possible to open a dispensing opening of the valve with a first movement of the adjusting element and a movement of the closing element connected thereto. The pressure then falls in a delivery space in which the adjusting element and the closing element are located. This reduces the gas pressure and the associated forces on the closing element. Therefore, a further movement of the closing element in an open position, in which the dispensing opening is fully opened, can be achieved with low magnetic forces.
    In a further embodiment of the invention, the delivery space is connected to a gas supply line which is guided through the magnet coil. This makes a compact construction of the valve possible.
    In a further embodiment, the adjusting element and / or the closing element are designed at least in a sub-area in an annular shape, wherein the sub-area of the adjusting elements / or of the closing element are facing the magnetic coil. Due to the annular design, the magnetic forces between the magnet coil and the magnetic device element or the magnetic closing element can be increased.
    In a further embodiment of the valve, activation surfaces are provided on the closing element and on the adjusting element, via which the closing element can be moved from the adjusting element in the direction of the magnetic coil. By providing activation surfaces, a simple and reliable means for forming a working connection between the adjusting element and the closing element is possible.
    In a further embodiment, a spring element is provided which biases the closing element into a closed position of the dispensing opening. In a further embodiment a second spring element is provided, which biases the adjusting element in the direction of the magnet coil. The spring element has a greater spring stiffness than the second spring element. A reliable closure of the dispensing opening in the closing position is thus possible.
    In a further embodiment, the adjusting element comprises an annular segment which comprises an annular segment of the closing element, the annular segments facing the magnet coil. As a result, a compact structure with an advantageous embodiment is made available for the magnetic forces of the magnetic coil.
    In a further embodiment, the magnetic coil comprises an annular base surface which is covered at least by a part of the annular segments of the adjusting element and of the closing element. An effective arrangement of the closing element and of the adjusting element with respect to the magnetic forces is thus possible.
    In a further embodiment, the adjusting element and the closing element are embodied such that the adjusting element and the closing element can be applied to the magnet coil in an open position. As a result, a defined position of the adjusting element and of the closing element is made available for the open position of the dispensing opening. The adjusting element and the closing element are therefore in a defined position, so that their control for closing the dispensing opening can be accurately fixed.
    The invention is explained in more detail below with reference to the figures.
    Figure 1 shows a schematic structure of a gas supply system for a combustion engine,
    Figure 2 shows a schematic representation of the valve for blowing in gas in a closed position,
    Figure 3 shows the valve in an intermediate position,
    Figure 4 shows the valve in an open position.
    Figure 1 shows in a schematic representation a gas blow-in system of an internal combustion engine 1. A gas storage tank 2 is provided, which supplies gas with a predetermined pressure, for example with a pressure of 200 bar. The gas storage tank is connected via a switch valve 3 to a gas line 4. The gas line 4 is connected via a pressure reducer 5 to a supply line 6. The pressure reducer 5 reduces the gas pressure of the predetermined storage tank pressure of, for example, 200 bar to an inlet pressure of, for example, 8 bar. The supply line 6 is guided to a valve 7, which is connected to a combustion space 8 of the combustion engine 1. Furthermore, a sensor 9 is provided on the combustion engine 1, which is connected via a sensor line 10 to a control device 11. Furthermore, the control device 11 is connected to a data memory 14.
    The control device 11 controls the switch valve 3 in an open or closed state, depending on whether gas is to be supplied from the gas storage tank 2 to the valve 7. Furthermore, the control device 11 detects via the sensor 9 at least one parameter of the combustion engine. For example, as a parameter of the internal combustion engine, the load and / or the gas position of a vehicle in which the internal combustion engine 1 is arranged can be detected. Depending on the loads / or the accelerator pedal position, the control device 11 controls the combustion engine. To this end, the control device 11 is connected to the data memory 14, in which tables and / or characteristics are stored.
    Figure 2 shows the valve 7 in a closed position. The valve 7 comprises a housing 40, in which a magnetic coil 41 is arranged in an upper area. The magnet coil 41 surrounds a cylindrical recess 42, which is connected to the supply line 6. A first spring element 43 is provided in the recess 42. The first spring element 43 is clamped between stops 44 on the inside of the magnet coil 41 and a closing element 45. The closing element 45 is arranged in a dispensing space 46 and closes off a dispensing opening 47. The closing element 45 is designed as a cylindrical body, which comprises a circular disk-shaped sealing surface 48. The sealing surface 48 is applied to an annular support surface 49. The annular support surface 49 surrounds the dispensing opening 47 on an inner side of the dispensing space 46. Opposite the sealing surface 48, the closing element 45 comprises an abutment surface 51, which also has a circular surface, and against which the first spring element 43. The abutment surface 51 is arranged in a center-symmetrical manner with respect to the cylindrical recess 42, the abutment surface 51 covering the recess 42 and protruding with an edge region above the recess 42 and covering a sub-ring surface 90 of a base surface 52 of the magnetic coil 41.
    The closing element 45 is surrounded by a sleeve-shaped adjusting element 53. The adjusting element 53 comprises a pot shape open on both sides, wherein the closing element 45 is guided through an opening 54 of a base plate 55 of the adjusting element 53. The closing element 45 with an annular activating surface 56 lies on an inner side of the bottom plate 55. The adjusting element 53 furthermore comprises an annular segment 57 which is directed towards the magnet coil 41. A second spring element 91 is clamped between the bottom plate 55 and the housing 40, which biases the adjusting element 53 in the direction of the magnet coil 41. Due to the greater spring stiffness of the first spring element 43, the closing element 45 lies on the support surface 49. Figure 2 shows the closing position, in which the adjusting element 53 has a first distance A from the magnetic coil. With the contact surface 51, the closing element 45 has a second distance B from the magnetic coil, that is to say from the base surface 52 of the magnetic coil 41. The first distance A is smaller than the second distance B.
    Furthermore, a guide surface 58 is provided, which guides the adjusting element 53 in a predetermined direction of movement 92. In the exemplary embodiment shown, the guide surface 58 is designed as a cylindrical partial circle surface.
    Depending on the selected embodiment, the guide surface 58 can also represent a sub-ring surface which comprises the cylindrical outer surface of the adjusting element 53. Moreover, the closing element 45 comprises a second and a third guiding surface 59, 60, which are each annular and are guided to the cylindrical inner surface 61 of the adjusting element 53.
    The adjusting element 53 and the closing element 45 are at least partially made of a magnetic material. In particular, regions of the adjusting element 53 and regions of the closing element 45 facing the magnet coil 41 are made of the magnetic material.
    If the magnetic coil 41 is now supplied, the adjusting element 53 is pulled in the direction of the magnetic coil against the biasing force of the first spring element 43 on the basis of the magnetic forces. Moreover, with the adjusting element 53, the closing element 45 is slightly raised from the dispensing opening 47, since the bottom plate 55 comes to rest against the activation surface 56 of the closing element 45. The adjusting element 53 comes into contact with the annular segment 57 the base surface 52 of the magnet coil 41. Due to the opened dispensing opening 47, the pressure of the gas in the dispensing space 46 decreases, as shown in Figure 3. This also reduces the gas forces acting on the closing element 45.
    Since the magnetic coil is further fed and the closing element 45 is located at a third distance C closer to the second distance B at the magnetic coil 41, the closing element 45 is pulled in the direction of the magnetic coil 41 by the magnetic force of the magnetic coil 41. The sealing surface 48 is thereby raised even further from the supporting surface 49, so that the dispensing opening 47 is fully opened, as shown in FIG. In this position, the closing element 45 lies with the contact surface 51 against the base surface 52 of the magnetic coil 41. The closing element 45 and the adjusting element 53 are therefore now in the open position.
    On the basis of the chosen embodiment, in the open position, the bottom plate 55 of the adjusting element 53 and the sealing surface 48 of the closing element 45 preferably form a flat surface. Due to the flat surface, swirls of the gas are avoided, so that a uniform outflow of the gas from the dispensing space 46 via the dispensing opening 47 is possible. This position is shown in Figure 4. In the open position, a large effective flow cross-section of the dispensing opening 47 is released, so that a high flow of gas is the result. On the basis of the described embodiments of the adjusting element 53 and of the closing element 45, relatively large gas pressures can be overcome with comparatively low electrical powers and high flow rates can be realized.
    If now the supply of the magnetic coil 41 via the electrical lines 63 is interrupted, the closing element 45 comes through the first spring element 43 with the sealing surface 48 against the supporting surface 49, as shown in FIG. the adjusting element 53 is moved back via the activation surface 56, against the spring force of the second spring element 91, to the starting position, as shown in Figure 2.
    Due to the two-stage opening method with the aid of two separate components, that is to say the adjusting element 53 and the closing element 45, it is possible, with the aid of slight magnetic forces, to first make a first stroke of the closing element 45 and a collapse of the gas pressure in the delivery space 46 to generate. The second hose of the closing element 45 is brought about by the magnetic force between the magnetic coil 41 and the closing element 45, whereby a larger effective flow cross-section of the discharge opening 47 is released.
