a leaf element

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. In the illustrated example, 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. Figures 7-9 do not illustrate the constructive details of the assembly V4, nor the actuator means of the movement of the leaf element discs S1 and S2, since they can be made in any known manner. For example, the two ends of each leaf element S1 and S2 could be connected to each other by means of a metal cable including a toothed portion engaged on a drive pinion, controlled by an electric motor.
