Embodiment Construction

[0020] figure 1 A partial area of ​​a motor vehicle 1 with a drive unit having a drive unit 2 is shown schematically. The drive unit 2 can drive the motor vehicle mechanically or supply electrical current to an electric drive (not shown). The drive unit has an exhaust line 5 and two supply channels 3 , 4 for fuel, for example gaseous fuel, and for fresh air. Power plant 2 may be, for example, a fuel cell or an internal combustion engine. A valve 7 actuatable by an electric drive 6 is arranged in the exhaust line 5 .

[0021] In an embodiment not shown, the valve 7 can also be arranged in the fresh air-conducting or fuel-conducting supply channels 3 , 4 .

[0022] The electric current generated by the drive unit 2 is fed to the control unit 8 . The control device 8 is connected to an on-board electrical system (not shown) of the motor vehicle. The electric drive 6 of the valve 7 is supplied with electric current via a control device 8 . A transmission 9 with a position se...

Abstract

A valve (7) for controlling exhaust gas or fresh air in a drive unit has an axial support (20) which is arranged at the free end of a drive shaft (14) for a valve body (15). The axial support (20) hasa securing ring (23) arranged between a cover (21), which is pressed into a valve housing (11), and a bearing arrangement (18). The cover (21) seals off the valve housing (11) and has a ring-shaped bead (26).

Description

technical field [0001] The invention relates to a valve for controlling exhaust or fresh air in a drive unit of a motor vehicle or generator / engine / prime mover, the valve comprising: a valve housing with a channel; The valve body for the flow cross-section / channel section for opening or closing the channel; the drive for the drive shaft to oscillate; the bearing for the drive shaft in the valve housing; and the drive shaft for the drive shaft in the valve Axial support in the housing. Background technique [0002] Such valves are used in particular in throttle valves or exhaust valves of motor vehicles today and are known from practice. The valve body is screwed onto the drive shaft and oscillates with it. The drive shaft is guided from the valve housing into a further housing of the drive, usually in the form of an electrical device. The end of the drive shaft remote from the drive has a bearing in the valve housing. The axial bearing ensures precise positioning of the ...
