Definitions

  • the invention relates to a valve device for a motor vehicle having a housing, a befind ⁇ union in the housing flow channel, a being arrange ⁇ th in the flow channel flap for closing the flow channel, wherein the flap is fixed to an axis, the axis of rotation in the housing is mounted and arranged in the flow passage valve seat, which is in the closed position of the flap in contact with this.
  • Such valve devices are used for example as Dros ⁇ selklappenstutzen or exhaust gas recirculation valve use and have long been known.
  • the pivoted flap By the pivoted flap, it is possible, the flow channel completely to open such striglie ⁇ SEN or so as the mass flow rate to re ⁇ rules. This can lead to the formation of ice in unfavorable environmental influences in Strö ⁇ flow duct and on the flap.
  • Insbeson ⁇ particular at a parked vehicle when the flap is in the emergency-running position in which it releases only a small gap of the flow channel, favors this position of the flap the formation of ice. As a result of the formation of ice a uniform movement of the flap is disturbed.
  • the formation of ice bad ⁇ prevent tight closure and easy opening of the flow channel through the valve.
  • a disadvantage of this valve ⁇ device is the complex housing design due to the coolant channel with the associated terminals.
  • the invention has for its object to provide a Ventilvorrich ⁇ tion, with the risk of ice formation in Strö ⁇ flow channel and / or on the flap is minimized. The object is achieved by the features of the independent claim.
  • a hydrophilic formation leads to this effect, since the hydrophilic surface attracts the water, which then runs in large quantities from the surface and thus leaves only a very thin film of water in the flow channel and / or on the flap, which is easily broken on freezing ⁇ can be. Due to this design of Strö ⁇ flow duct and / or flap no other measures to prevent the formation of ice in the valve device are require sary. In particular, the provision of a channel in the housing for heating the valve device is not necessary. The cost of the housing there ⁇ by grace can be significantly redu ⁇ . In addition, the valve device according to the invention requires a significantly smaller space due to the non-existing connections of the channel.
  • un ⁇ ter hydrophobic training is also meant a superhydrophobic or eisphobe training or under hydrophilic Ausbil ⁇ dung a super hydrophilic training.
  • the flap is hydrophobic or hydrophilic by being provided with a plasma coating. A reduced effort is achieved with the hydrophobic formation when the plasma coating is formed on only one of the two parts. In different conditions, however, the hydrophobic formation of the flow channel and the flap has been proven.
  • the training hydrophobic in a hydrophobic coating which is associated with ge ⁇ little effort in the flow channel and / or the flap up.
  • the expense for the coating can be further reduzie ⁇ reindeer, if only the area of the valve seat in the flow channel or in the near vicinity of the area of the valve seat in the flow channel comprising the hydrophobic or hydrophilic Plasmabeschich ⁇ processing.
  • the cost of the coating can be reduced if the hydrophobic plasma coating is arranged only on one side of the flap.
  • the hydrophobic or hydrophilic formation can be created by a nano-structured surface of the flow channel and / or the flap.
  • Area of the valve seat and / or the flap and / or only on one side has the nanostructured surface.
  • FIG. 1 shows a valve device according to the invention
  • Fig. 2 the flow channel of the valve device according to
  • FIG. 1 shows a throttle body with a housing 1, located in the housing flow channel 2, in which a disk-shaped flap 3 is arranged.
  • the flap 3 is fixedly connected to an axle 4 and the axle 4 is rotatably mounted in the housing 1.
  • the axis 4 is driven by an element located in the housing 1 an electric motor 5, wherein Zvi ⁇ ; the axles 4 and the electric motor 5, a gear 6 is penetratege ⁇ on.
  • FIG 2 shows a portion of the flow channel 2 of Figure 1 in section.
  • the disc-shaped flap 3 is rotatably connected by means of a welded connection.
  • the flap 3 is opened approximately halfway. The sealing takes place via a sealing ring 7, which is arranged in a groove of the flap 3.
  • the flap 3 seals the flow channel 2.
  • Both the zy ⁇ -cylindrical valve seat 8 and the valve 3 are provided with a hydrophobic or hydrophilic coating by egg ne plasma coating was applied.
  • the material of the flap and / or the valve seat is coated with thin layers, which are formed by the action of a plasma on powders injected into it.
  • the flap and / or the valve seat Kgs ⁇ NEN this purpose are made of metal, for example aluminum or steel, or from a plastic.
  • the flap and / or the valve seat for example, after a very thorough cleaning, in a vacuum chamber ⁇ introduced and fixed there.
  • the chamber is run according to the Ver ⁇ evacuated relate to a residual gas pressure in the high-vacuum Ultra-high vacuum range is reached.
  • a working gas usually argon
  • Energyein ⁇ contract for example, microwaves, high frequency, electrical discharge
  • the injection of powders into a plasma can lead to the deposition of a hydrophobic or hydrophilic layer, depending on the choice of the precursor.
