The rotation angle sensor unit 93 consists of a stationary unit 93.1 and a rotating unit 93.2. The rotating unit 93.2 is with the throttle valve shaft element 99 connected while the stationary unit is held in the throttle valve housing element 98. In the Throttle body element is also how 3 shows, in particular, the valve unit 95 integrated.
  • the valve unit 95 has a connecting piece 95.1 for a rubber hose. It is through a fuel vapor recess 102 with the interior of the gas mixture cavity connected.
  • the valve unit 95 has the task especially those of the tank or activated carbon filter
  • the fuel gas vapors are vented accordingly Taxes.
  • It is an electromagnetically actuated valve (AKF valve), comprising a ring-shaped Magnetic coil, one in the axial direction of the magnetic coil reciprocating magnetic armature made of metallic Material encloses, the magnetic armature on the End face facing the valve seat with a sealing body elastomeric material is provided.
  • the magnet armature and the Sealing bodies are positively connected to one another.
  • At the electromagnetically actuated valve is a complete component from K. Freudenberg, the described in detail in EP-A-623 772 in particular is.
  • the central plug unit is opposite the valve unit 96 arranged.
  • the central plug unit is 4 shows, in particular, from a connector housing 96.1, which holds plug contact elements 96.3. Inside the Connector housing 96.1 is a temperature sensor holder element 96.2 arranged that the temperature sensor unit 94 holds.
  • the temperature sensor unit is one in itself well-known NTC temperature pill.
  • On one of the outside of the A connector 96.4 is arranged in a connector housing 96.1. Through them can lead lines and the like will.
  • valve unit 95 By integrating the valve unit 95 into the throttle valve housing element 98, the path to the gas mixture cavity 103 is reduced.
  • the line duct 101 replaces the rubber line normally used and thereby not only increases the stability of the connection, but above all has a positive effect on the transmission properties. Due to the short and stable duct, there is no turbulence.
  • the line channel 101 enables the line connections between the throttle valve control unit 8 with the Throttle valve drive unit 91 and the angle sensor unit 93 on a very short and above all before mechanical way to make protected way. over the line channel 101 will also be the lines from the throttle valve control unit 8 and the valve unit 95 led to the central plug unit 96.
