Definitions

  • the invention relates to a valve and a method for producing a valve.
  • valves are known, for example as a throttle valve in the air intake tract of an internal combustion engine. If you want to use such valves, for example, as a throttle valve in an air intake tract of an internal combustion engine, it is disadvantageous that the previously known valves have to be laboriously preassembled from several parts.
  • the manufacturing tolerances in the closing area are very precise so that the amount of leakage air does not exceed a certain order of magnitude. It is also important that the closing area be followed by a subsequent accuracy area in order to ensure that when the throttle valve is operated there are no abrupt changes in flow which subsequently cause the internal combustion engine speed to increase abruptly.
  • the accuracy of the gap width is guaranteed by the use of two-component injection molding technology.
  • the accuracy range has a progression zone and / or a closing range and a passband. This differentiated division of the accuracy range guarantees safe and controlled opening and closing of the valve with defined passage conditions.
  • the movable element is a flap which can be rotated about the bearing areas. By using a flap, it is possible to accommodate the valve mechanism completely in the intake manifold cross section.
  • the accuracy range with respect to the final closed position is between - 20 degrees and + 20 degrees.
  • the flow conditions in the pipe can be suitably, e.g. change very precisely with one stone.
  • the passage area is between 5 degrees and 90 degrees with respect to the final closed position.
  • a minimum range for the closure is required, which is in the range up to about 5 degrees.
  • a flap inclined by up to about 5 degrees to the cross-sectional area represents a flow resistance that suitably supports the closing effect.
  • An advantageous development of the invention provides that the flow area is designed such that the gap between the moving and the fixed element increases with increasing opening angle of the movable element.
  • Another advantageous development of the invention provides that the bearing clearance due to the different shrinkage of the valve axis and the fixed element z. B. is adjustable by means of adjusting screws in the area of the flap axis.
  • a method for producing a valve is shown.
  • the valve is manufactured in the so-called two-component injection molding process, i. H. first a component, i. H. the nozzle, manufactured, then the throttle valve is cast after a tool movement and formation of a cavity.
  • the nozzle is manufactured in a first operation, then at least one slide of the injection molding tool is opened and the throttle valve is cast
  • the slides extending into the connecting piece are designed as partial slides. These slide valves are separated approximately in the middle, two of the four slide valves being removed to produce the cavities for the throttle valve and replaced by further slide valves. The removal and replacement takes place in a particularly advantageous manner on a turntable on which the tool is arranged.
  • the pivots can also be cast simultaneously with the throttle valve. To avoid accumulation of material and for easy attachment of a throttle valve actuator, cavities are formed in the trunnions during manufacture.
  • Figure 1 shows a valve in a sectional view
  • Figure 2 shows a tool for the manufacture of the valve
  • FIG. 3 shows the tool according to FIG. 2 with exchanged slide elements
  • Figure 4 shows a throttle valve in a side view
  • Figure 5 shows an adjusting device of the throttle valve.
  • the valve shown in the figure has the function of a throttle valve and consists of a housing 10 which is formed in one piece and in which a throttle valve 11 is arranged so as to be rotatable about the axis 12.
  • the throttle valve moves within a defined swivel range in a connection piece 13.
  • This connection piece has a spherical zone in the area 14 and a sealing zone at the contact area 15 of the throttle valve.
  • valves All parts of the valve are made of plastic, the throttle valve 11 and the nozzle 13 being produced in the so-called two-component injection molding process.
  • the tool then opens in a sectional plane that corresponds to the position of the throttle valve by the amount of the throttle valve thickness, so that the throttle valve is produced in the subsequent operation. Since the nozzle and the throttle valve are injection molded in one tool, neither is created The center offset still creates tolerances that lead to leaks between the connector and the throttle valve.
  • either the throttle valve 11 or the connecting piece 13 is produced in an injection molding machine and then extrusion-coated with the counterpart in a subsequent operation.
  • the immediately successive injection molding of the nozzle and throttle valve causes the plastic mass of the throttle valve to seal against the plastic of the nozzle. Since the plastic mass of the nozzle has already cooled and the cooling process of the throttle valve only begins later and the shrinkage of the throttle valve also begins later, a precisely defined gap is created between the nozzle and throttle valve, which can be optimized in terms of process technology.
  • the production in the two-component injection molding process has the advantage that a very large angular range of the adjusting angle of the throttle valve can be designed as a so-called accuracy range.
  • This accuracy range alpha is designed as a spherical zone and can either be used as a sealing area or as an area that allows the plastic throttle valve to open progressively. This makes it possible to either perform an idle air control with a plastic throttle valve in internal combustion engines or to map a control characteristic that causes small flow changes near the closing area of the throttle valve with very long travel ranges and only increases the flow gradient from a larger opening angle.
  • Figure 2 shows a section of a tool in which the complete valve, ie. H. Throttle valve 11 and connector 13 are made.
  • the injection mold consists of two mold halves 16, 17. To produce the connector 13, two half cores 18, 19, 20, 21 are moved into the cavity, and then the cavity for the connector 13 is filled with plastic. In a further operation, the half cores 18 and 21 are removed and two modified half cores 22, 23 are used. Its front end edge is set back relative to the half-cores 18, 21, so that a cavity for the throttle valve 11 is formed. This cavity is filled with thermoplastic. After the plastic has cooled, all cores are removed. Depending on the design of the half cores 22, 23, the wall thickness of the Throttle valve can be varied. There is also the possibility of providing ribbing or the like.
  • FIG. 4 shows a throttle valve in a side view.
  • the throttle valve with the pivot pin is produced in one operation.
  • cylindrical pins can be inserted into the interior during manufacture. After removing these pins, the bores 24, 25 form.
  • the pivot pins extend in an advantageous manner only over part of the throttle valve 11. This allows the throttle valve to be particularly advantageous in terms of flow.
  • Metal pins or the like can be introduced into the bores 24, 25 during the final assembly. Above all, it is possible to attach the throttle valve actuator via one of the holes. For example, a metal web can be pressed into one of the bores for transmission of an actuating movement.
  • FIG. 5 shows an exemplary embodiment in which the adjustment of the valve axis 12 of the valve 11 in the socket 13 by means of adjusting screws 26 can be seen.
