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 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 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 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.
