Abstract
In a throttle valve actuator unit having a throttle valve neck that contains a pivotable throttle valve and having a drive chamber for receiving an electric drive mechanism for the throttle valve and for receiving an electric connection plug for a plug connection to a control unit, in order to reduce the production costs while maintaining the many customer-specific characteristics, the drive chamber is enclosed by a housing module, and the throttle valve neck is attached as a separate part to the housing module and secured thereto.
Claims17
A throttle valve actuator unit, having a first module comprising
- a throttle valve neck (11),
- a throttle valve shaft (14) carrying a throttle valve (13) rotatably supported, on the valve shaft, and
- a second module, also called a housing module, comprising
- a drive chamber for receiving an electric drive mechanism for the throttle valve shaft (14) and for receiving an electric connection plug (20) for a plug connection for a control unit,
- the drive chamber being enclosed by the housing module (12), to which the throttle valve neck (11) is attached as a separate part and secured,
- so that only one of the two modules needs to be adapted to meet varied customer specification, without any change in the other module.
