Ventilating and air conditioning device for motor vehicle, has hot air passage with cross section larger than cool air passage, and slide valve with guide rail specifying curve in cool passage, where curve length corresponds to valve length

摘要

The device has a temperature control system and a flexible slide valve (14) for opening, throttling and losing a cool air passage (9) and a hot air passage (10). The hot air passage in a heat exchanger has a cross section larger than the cool air passage. The slide valve has a guide rail that specifies a curve in the cool air passage, where the length of the curve corresponds to the length of the valve.
