Motor vehicle heating system controller - has levers controlling air inlet, fan, valve and heat exchanger

摘要

The lever and rotating assembly are used to control the heating system in motor vehicles. The transmission ratio is sensibly constant for the large operating range of the assembly. One rotating knob is mounted on the vehicle dashboard to control air inlet and a fan while a second knob controls a valve on heat exchanges and airflow. Levers articulate around axes parallel to the knob axes. Bowden cables are attached to free ends of levers with sheath attached to a support on a housing. An index enables the user to observe position of the lever.
