The invention relates to a fixing unit comprises a multi-part, electrically conductive base body provided with connections for the electric power supply of the electrically conductive basebody and additional connections for the electric motor and which is arranged in an electrically non-conductive support comprising at least two fixing holes. The multi-part, electrically conductive base body and the electrically non-conductive support are provided with a common recess.

Fixing unit for an electric motor

The present invention is directed to a housing flange unit which includes a housing flange wherein a butterfly valve shaft is rotatably mounted in a perpendicular position in relation to the longitudinal axis of the housing flange and includes a butterfly valve which is arranged in the middle and provided with a first bearing and a second bearing. The butterfly valve shaft includes a circular disk on the outside of the first bearing. The disk engages with a cup-shaped seat of the housing flange. A pot-shaped element with a circular recess is fixed in the cup-shaped seat. The circular disk is embedded in the pot-shaped element. The invention also relates to the use of the housing flange unit as a sealing unit.

Housing flange unit

A throttle body ( ) with a housing ( ) comprising a housing cover ( ) and a housing body ( ) and with a through throttle aperture ( ) for a throttle butterfly ( ) arranged on a throttle-butterfly shaft ( ), the throttle-butterfly shaft ( ) being drivable as a function of specifiable parameters by an electronic system ( ) arranged in the housing ( ) by an electric actuator ( ) likewise arranged in the housing ( ) and having an actuator shaft ( ), the position of the throttle-butterfly shaft ( ) being detectable by a position detection device ( ) arranged in the housing ( ), is to have a particularly small space requirement and, at the same time, a contactless position detection device ( ) for the throttle-butterfly shaft ( ) For this purpose, the electronic system ( ) for the electric actuator ( ) is arranged in the housing cover ( ), and the position detection device ( ) comprises a Hall-effect magnet ( ) arranged on the actuator shaft ( ) and a Hall-effect sensor ( ) arranged directly next to the Hall-effect magnet ( ) for detecting the position of the throttle-butterfly shaft ( ).
