English to French Tech/Engineering Automotive / Cars & Trucks (in a patent) Motor-vehicle auxiliary ventilation System

Each of the two valves V1, V2 comprises a gate valve disc S1 or S2, which is slidably guided between a first end position in which it completely obstructs the outlet opening B1 or B2 and leaves an opening formed on the lower side of the valve body free, and a second end position, in which the gate valve disc S leaves the outlet opening B1 or B2 free and obstructs the lower opening.

the valve System comprises a first shutter valve V1 which is configured to obstruct the passage 220 or leave it open, a second valve V2 which is configured to obstruct the passage 230 or leave it open, and a third valve V3 which is configured to obstruct the passage 210 or leave it open.

each of the two discs S1 and S2 consists of a leaf element guided in a slidable manner along an L-shaped path between its two opposite end positions.

the disc S1 leaves the outlet B1 free, while the disc S2 obstructs the outlet B2, so that the air cooled by the evaporator E continues towards the vehicle passenger compartment. In this condition, the heat of the condenser is discharged through the unobstructed lower opening.

the disc S2 leaves the outlet B2 free, while the disc S1 obstructs the outlet B1, so that the air heated by the condenser D' continues towards the vehicle passenger compartment.
