Definitions

  • the throttle valve adjusted with a servomotor. That kind of Throttle valve adjustment is under the technical term Drive-by-wire known.
  • the servomotor is with a Throttle valve shaft connected, which rotates in the housing is stored.
  • valve unit which in itself is the Task is to release fuel vapors emitted by the tank, is targeted for further use.
  • the valve unit By a targeted control of the valve unit assumes this Failure of the actuator unit the task, the air flow cavity to provide so much air that a sufficient, ignitable mixture is available that enables the driver to specifically target his vehicle from the To move the danger zone or to another location.
  • control unit in the housing cover element or is arranged in the housing element ensures that the corresponding control signals can be transferred immediately.
  • the valve unit can be operated electromagnetically Valve, which is a substantially annular solenoid includes a back and forth in the axial direction movable magnetic armature made of metallic material encloses, the magnet armature on the the valve seat facing end face with a sealing body made of elastomer Material is closed and the magnet armature and the Sealing bodies are positively connected to one another.
  • electromagnetically Valve which is a substantially annular solenoid includes a back and forth in the axial direction movable magnetic armature made of metallic material encloses, the magnet armature on the the valve seat facing end face with a sealing body made of elastomer Material is closed and the magnet armature and the Sealing bodies are positively connected to one another.
  • 1 and 2 is part of a drive-by-wire system shown.
  • the rotating unit 93.2 is connected to the throttle valve shaft element, while the stationary unit in the throttle body element 98 is held.
  • the throttle body member 98 furthermore, as shown in FIG. 2, encloses a valve unit 95.
  • the valve unit 95 has a connecting piece 95.1 for a rubber hose. It is through one Force vapor recess 102 with the interior of the gas mixture cavity 103 connected.
  • the valve unit 95 has itself the task, especially that of the tank or activated carbon filter the gasoline vapors corresponding to the tank ventilation Taxes.
  • an electromagnetically actuated valve comprising a ring-shaped Magnetic coil, one in the axial direction of the magnetic coil back and forth movable 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.
  • valve unit 95 Opposite the valve unit 95 is a central plug unit 96 arranged. There is a duct in the housing element 101 provided. Encloses the housing element 98 in addition, a throttle valve control unit 106.
  • the Servomotor unit 91 with the rotor unit 97 ensures this that the throttle valve angle from the throttle valve closed position up to full throttle accordingly is adjusted. This ensures an air throughput, the one for providing an appropriate Mixture is required. With the help of the angle sensor unit 93 the corresponding throttle valve angle is measured and provided for further processing.
  • the valve unit 95 with an emergency position signal controlled.
  • the emergency position signal leads to a permanent opening of the valve unit 95, namely Opening so wide that an air flow of about 40 kg air / h is guaranteed.
  • This air is released from the tank or via the activated carbon filter of the tank ventilation Air flow cavity 103 supplied.
  • the so fed Air volume is sufficient to get the vehicle out of a danger zone move it out or take it to a workshop to fix the Driving damage.
  • Actuation of the valve unit 95 should be done in such a way that it differs from the usual control signals used is independent. It's closed ensure that even if the control unit or the power supply to the throttle valve unit 90 separate control of the valve unit 95 is given.
