Definitions

  • the present invention relates to a control box according to the preamble of claim 1.
  • Control boxes of this type are typically used in the automotive field to translate a control signal into a mechanical movement and to feed it to the part to be controlled.
  • control boxes are used in turbochargers, where, for example, they open and close the valve flap of the exhaust gas bypass in the turbine housing in accordance with the requirements of the driving situation.
  • an overpressure control box consists of an upper chamber 4 and a lower chamber 6, which are separated from one another in a gas-tight manner by a membrane 12.
  • the upper chamber 4 has a control line 10, by means of which either a pressure corresponding to the atmospheric pressure At or an overpressure up to a maximum pressure P max can be set in the upper chamber.
  • the currently set pressure can therefore vary from At to P max .
  • a coil spring 3 is arranged in the lower chamber 6 in such a way that it pushes the membrane upwards.
  • the membrane 12 is connected to a rod 14 in such a way that the rod 14 is pulled or pushed axially in the same direction when the membrane deflects in one or the other direction (up or down).
  • this movement of the rod 14 causes a valve flap 18 to be lowered onto its valve seat 19, thus closing the valve.
  • the force of the spring 3 is chosen to be relatively large, since when using such an overpressure control box to close the bypass valve, a relatively large force has to be applied, since the bypass is relatively low is high pressure, which is formed by the exhaust gas expelled from the cylinders of an internal combustion engine.
  • FIG. 2 A typical known vacuum box is shown in Fig. 2.
  • the vacuum box in Fig. 2 also has an upper chamber 4a and a lower chamber 6a, which are separated from each other by a gas-tight 12a.
  • a control line 10a can be connected to a vacuum source, not shown.
  • the lower chamber is open and is constantly at atmospheric pressure.
  • the spring is arranged in the upper chamber, so that at atmospheric pressure on both sides of the membrane 12a, the spring 3a presses the membrane and with it the rod 14a downward, the valve 18, 19 being opened.
  • Fig. 3 shows such a bi-pressure control box in principle.
  • Upper chamber 4b and lower chamber 6b are also separated from one another in a gas-tight manner by a membrane 12b.
  • the upper chamber has a control line 10b for applying a negative pressure in the upper chamber and the lower chamber has a control line 20 for applying a positive pressure in the lower chamber.
  • the lower chamber 6b is closed by a seal 22, which, however, allows the rod 14b to move axially.
  • the bi-pressure control box according to FIG. 3 combines the advantage of the control box according to FIG. 1 (large closing pressure due to a strong spring) with the advantage of the control box according to FIG. 2 (use of negative pressure), but loses this latter advantage through the additional use of overpressure.
  • FIG. 4 shows the principle of a control box of the invention.
  • control box is separated in a gas-tight manner by means of a membrane 3c into an upper 4c and a lower chamber 6c.
  • the lower chamber has a spring 3c and the upper and the lower chamber have connecting lines 10c, 22c to a vacuum source, not shown.
  • the upper chamber can either be set to atmospheric pressure At, or can be set to negative pressure, and the lower chamber likewise.
  • This spring force can be relatively large, as is desired, but is still supported by the negative pressure in the upper chamber and is not weakened, as in FIG. 1, by the atmospheric pressure set as the minimum pressure for valve closing.
  • control socket of the invention offers the advantage of not requiring overpressure, as the control sockets according to FIGS. 1 and 3 do, and that they are compared to the control socket of FIG 2 has the advantage of using the spring force in the direction of valve closing so that they use a strong spring 1 as in the control box according to FIG. 1, while the control box according to FIG. 2 receives its closing force from the negative pressure alone, and even minus the spring force.
  • FIG. 5 shows a real embodiment of a control box according to the invention in a sectional view, the control box being formed from an upper housing 30 and a lower housing 31.
  • the upper and lower housings are connected to one another by flanging and the edges of the two housings clamp a membrane 38 between them, so that the membrane divides the control box into an upper pressure chamber 32 and a lower pressure chamber 33.
  • the upper pressure chamber 32 can be set to any value between normal pressure and maximum negative pressure by means of a suction line 34 and the lower pressure chamber 33 by means of a suction line 35.
  • the diaphragm 38 is held exactly radially by two plate elements 39 and 40, and if the existing pressure is changed in one of the chambers, the diaphragm yields in one direction or the other in accordance with the new pressure conditions and pulls or pushes the control rod 36 along with it itself, so that a targeted pressure change in one or both of the pressure chambers produces a targeted movement of the control rod.
  • a spiral spring 37 is arranged such that it prestresses the membrane in the direction of a reduction in the size of the upper pressure chamber.
  • the lower housing has an inverted conical pot 41 which serves on the one hand to seat the spiral spring 37 and on the other hand to accommodate a sealing arrangement.
  • the sealing arrangement consists of two bearing elements 42 and 43, which tightly enclose one end of a flexible conical seal 45 between them in the region of a recess 44, while the other end of this seal 45 sealingly engages in a circumferential groove 48 of the control rod under internal stress.
  • the lower bearing element 43 has a recess 46 in which an O-ring seal 47 is arranged, as a result of which the lower pressure chamber is sealed off from the outside, as is by the seal 45.
