Embodiment Construction

[0016] figure 1 A longitudinal section view of the valve is shown. The valve comprises a housing 1 with a valve seat 2 for a valve flap 3 which is rotatably supported on a drive shaft 4 . The drive shaft 4 is guided through the housing 1 on both sides. In this region, a sleeve 5 is arranged in a stationary manner in the housing 1 , through which sleeve the drive shaft 4 is rotatably guided. The sleeve 5 has a first region 5a which faces the valve flap 3 and surrounds the drive shaft 4 with a first gap. Furthermore, the sleeve 5 has a second region 5 b facing away from the valve flap 3 and having an enlarged diameter compared to the first region 5 a and enclosing the drive shaft 4 with a second gap on its end face facing away from the valve flap 3 . A storage space 8 is formed by the diameter expansion, which is suitable for collecting pollutants or condensed water. An annular seal 6 and a bearing 7 are arranged around the drive shaft 4 in the vicinity of the end face of t...

Abstract

The valve comprises a housing (1) having at least one valve seat (2) for at least one flap (3), which is supported so it can rotate on a drive shaft (4). The drive shaft (4) is guided on at least one side through the housing (1), a sleeve (5), through which the drive shaft (4) is rotatably guided, being disposed fixed in place on the inside of the housing (1) in this area. The sleeve (5) has a first area (5a), which faces the flap (3) and encloses the drive shaft (4) with a first slight play. Furthermore, the sleeve (5) has a second area (5b), which faces away from said flap (3) and has a diameter expansion in comparison to the first area (5a) and which, on the front side thereof facing away from the flap (3) encloses the drive shaft (4) with a second slight play. Furthermore, the object of the invention is the use of the valve as a gas recirculation valve of a motor vehicle.

Description

technical field [0001] The invention relates to a valve and an application of the valve. Background technique [0002] Valves are known, for example, for gas passages. In DE 10 2005 051 305 A1 a valve is described which comprises a housing with a first valve seat for a first valve flap and a second valve seat for a second valve flap, the valves The petals are rotatably supported on the drive shaft. The drive shaft of the valve is guided through a part of the housing between the first valve flap and the second valve flap. A disadvantage of such valves is that contamination or condensed water droplets in the flow medium can penetrate into the bearings or seals of the drive shaft and damage them in a disadvantageous manner. Contents of the invention [0003] It is therefore the object of the present invention to provide a valve in which the ingress of contaminants or condensation into the bearings and seals of the drive shaft can be avoided as far as possible. The object ...
