Beschreibung
Zusammenfassung:	An air conditioning device for an automobile vehicle includes the provision for automatic proportional control of the air conditioning function and also a priority function such as vehicle windscreen demisting or defrosting. Economy of pneumatic power is achieved by providing, with a double threshold control system, a signal for operating pneumatic flow distributors in the driving fluid lines to pneumatic jacks driving the control elements of the air conditioning device by means of an electrical signal which is capable of being either continuous or discontinuous in which latter state the flow distributor to which the discontinuous signal is applied is caused to oscillate to achieve an intermediate pneumatic pressure between pressure values corresponding to fully open and fully closed positions of the air conditioning control elements to be manipulated.
