Abstract
Abstract A heater actuating system regulatable on the air-side in a motor vehicle, which includes at least one adjusting lever that actuates a pneumatic rotary slide valve by means of which vacuum or atmospheric pressure is adapted to be conducted to a working element actuatable thereby which, in turn, opens or closes a valve in the feed line of the heating medium to a heater body; one adjusting lever, preferably a manually actuatable adjusting lever is thereby provided for the warm air discharge of each of the two sides of the motor vehicles whereby the adjusting lever during its deflection in one direction increasingly opens air slots and during the beginning of this deflection simultaneously adjusts an associated pneumatic rotary slide valve in one direction; the adjusting lever, during its deflection in the opposite direction thereby increasingly closes the air slots and at the end of its return pivot movement returns the pneumatic rotary slide valve again into its starting position.
