Definitions
- a valve device for a motor vehicle having a housing, a be ⁇ -sensitive in the housing flow channel, a being ⁇ arranged in the flow channel flap for closing the flow channel, wherein the flap is fixed to an axis, the axis is rotatably mounted in the housing and a valve disposed in the flow passage valve seat, which is in the closed position of the flap in contact therewith.
- valve devices are used for example as throttle body or exhaust gas recirculation valves use and have long been known.
- By the rotatably mounted flap it is possible to completely close or open the flow channel, so as to control the mass flow rate. Since a high control quality is required especially in the area with a small opening angle, the flap and seal design is of particular importance.
- the seal is mechanically stressed by the opening and closing, which is why the seal is arranged in the housing and not on the flap.
- valve ⁇ device For this purpose, it is known to heat the housing of the valve ⁇ device by a channel in the housing around the flow around a channel, which is connected to the water cooling ⁇ circuit of the internal combustion engine. The cooling water thus causes the heating of the housing.
- a disadvantage of this valve device is the complex housing design as a result of the coolant channel with the associated connections. It is also known to design the flow channel with an anti-ice coating, which, however, also has an increased effort.
- the invention has for its object to provide a valve device, with a high control quality in the range of small opening angle is achieved until complete closure of the flow channel. The valve device should also avoid blocking the flap due to ice formation with little effort.
- the seal is arranged in Strö ⁇ mungskanal that the flap facing side of the seal has a region of greater wall thickness than the remaining cross-sectional area and this area of the flap in the closed state opposite.
- the range of greater wall thickness extends in an advantageous embodiment of the range of greater wall thickness over a pivot angle range of the flap of 8 ° to -8 °, preferably 5 ° to -5 °, in particular from 2 ° to -2 ° extends, with larger diameters rather small pivoting ranges are selectable.
- the closed position of the flap corresponds to 0 °.
- the range is larger
- the slightest wear between the seal and the flap is achieved in that the region of greater wall thickness has a curvature pointing in the direction of the flap.
- This design ensures that the area in which touch seal and flap is spatially reduced to a minimum.
- the use of sealing lips allows high elasticity over a large area, since sealing lips have a narrow cross-sectional area compared to the rest of the sealing body.
- the desired flexibility is ensured by the two legs of the cross-sectional area, which is adjustable over the thickness of the legs within certain limits.
- a high flexibility is achieved when one of the legs of the Dichtungsgueritess of the flap is facing, while the other limb bears against the receptacle for the seal in Strö ⁇ flow duct.
- the seal Due to the abutment of the legs, the seal has a well-defined position, which in this orientation only minor Lüverixe- allow the ments coming in contact with the flap, which ultimately allows an exact adjustment of the medium flowing through the flow channel.
- the seal can be made with narrow cross-sectional area but sufficient dimensional stability, if the seal has a reinforcing profile.
- the reinforcing profile is U-shaped or V-shaped according to the cross-sectional area. In this way, the legs can support in their function.
- the reinforcing profile can be arranged within the cross-sectional area.
- a simpler manufacture of the seal is provided when the reinforcing profile is arranged extending over the inside of the legs, so that it is in contact with one side with the seal and the opposite surfaces of the profile are freely visible. If the reinforcing profile has a spring effect, this embodiment allows a further reduction of the cross-sectional area of the seal, since the elasticity of the seal no longer has to be realized exclusively via the material and its cross section. As a result, the seal can be produced more cheaply.
- a good flexibility is achieved with a seal made of an elastomer, while an ice formation in the region of the seal is achieved with a formation of the seal made of PTFE.
- the arrangement of the seal is particularly simple if it is arranged in a receptacle of the flow channel.
- the receptacle is a radially encircling groove.
- the production of the receptacle is considerably more cost-effective if the receptacle is a step, and the seal on the heel is applied.
- a clamping ring can be provided, which fixes the seal in this position.
- FIG. 1 shows a valve device according to the invention in section
- Fig. 2-5 different embodiments of the seal
- Fig. 6 is an enlarged view of the seal.
- FIG. 1 shows as a valve device a throttle body with a housing 1, a flow channel 2 located in the housing, 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 axle 4 is driven by an electric motor 5 via a gear 6.
- FIG. 2 shows the flap 3 in the flow channel 2 in the closed position.
- the flap 3 is applied to a seal 8.
- the seal 8 bears against a shoulder 9 of the flow channel 2 formed as a receptacle and is fixed in this position by a clamping ring 10.
- the seal 8 has a U-shaped cross-section, wherein the apex 11 and a leg 12 of the seal 8 abut the shoulder 9 and a leg 13 is in contact with the flap 3.
- the flap 13 facing the leg 13 has a greater wall thickness than the other leg 12 and the apex 11.
- the region of greater wall thickness 14 is formed as the flap 3 facing buckle, so as a precise sealing of the flow channel 2 through the flap 3 enable.
- the seal in Figure 3 has over the seal of Figure 2 is a 90 ° rotated cross-sectional area with a radially inner vertex 11. At this vertex 11, the flap 3 is in the closed position, the apex 11 has a greater wall thickness than the legs 12, 13 has.
- Figures 4 and 5 show seals 8 in the alignment according to Figures 2 and 3, wherein the seals 8 differ in that they each have a reinforcing profile 15 to support the dimensional stability.
- the reinforcing ⁇ profile 15 is disposed on the respective inner side of the legs 12, 13. But it is also conceivable to arrange the reinforcing profile 15 completely within the seal 8, so that it is not visible.
- the seal 8 in Figure 6 differs in structure from the seal 8 of Figure 2 in that the region of greater wall thickness 14 is not formed as a curvature but as a plateau 16 ⁇ . Such a configuration is also possible with the seals 8 of FIGS. 3 to 5.
