Patent DE-19816329-A1 (DE)
Title: Heating or air conditioning system for vehicles
Inventor: AROLD KLAUS
IPC: B60H1/00
Filed: 1998-04-11
Abstract: The system has at least one mixing chamber (17,18) with hot (21) and cold (22) air inflow orifices each with control flaps (23,24), with hot air passing over a heat exchanger (12) that has a shutoff valve (16) in the inflow or outflow of the heating medium. The flaps and shutoff valve are controlled so that the shutoff valve closes when the hot air inflow flap is closed, and then opens the flap again once the valve is fully shut. The system has a heat exchanger, through which a heating mixture flows, that is arranged in an airflow air duct that has at least one air-mixing chamber which includes a hot air inflow orifice for air flowing from the heat exchanger and a cold air inflow orifice for air flowing around the heat exchanger. The cross-sections of the inflow orifices are controlled by at least one air flap that is pivotally mounted on a pivot shaft and a shutoff valve is arranged in the inflow or outflow passage of the heat medium to or from the heat exchanger. Each flap and the shutoff valve are connected by an actuating lever (32,33,34) to a control disc (28) which is driven by an electric motor (29) so that, through rotation of the control disc, the shutoff valve is closed when the hot-air orifice air flap is closed and then after the shutoff valve is completely closed transfers the hot air orifice flap to a completely open position.
