Abstract:
PCT No. PCT/DE89/00547 Sec. 371 Date Apr. 20, 1990 Sec. 102(e) Date Apr. 20, 1990 PCT Filed Aug. 23, 1989 PCT Pub. No. WO90/03285 PCT Pub. Date Apr. 5, 1990.A heating system for a passenger compartment of a motor vehicle includes a heat exchanger located in the passenger compartment and a feeding conduit extending between the heat exchanger and the cooling circuit of the vehicle internal combustion engine and connected to the cooling circuit at a point downstream of the internal combustion engine in a direction of liquid flow. A return conduit extends between the heat exchanger and a delivery unit of the cooling circuit. The heating system also includes a shut-off device for blocking flow of heat to the heat exchanger. The shut-off device has first and second chambers and inlet and outlet ports communicating with the first chamber. A pressure port communicates with the second chamber and is connected with the feeding conduit. A wall separates the first and second chambers. The wall is movable between a first position in which it blocks communication between the inlet port and the outlet port, and a second position in which it closes the pressure port and provides for communication between the inlet and outlet ports.
