Control device for a flow of gas in a channel

摘要

The control device for a gas current fed into a channel is applicable to the air flow in an air-conditioning plant in a road vehicle and involves an installation frame provided with pivotable lamellas (2) activated by a gear with an electric motor fitted on the frame. The gear through the superimposed arrangement of several face wheels is so narrowingly formed that the total dimensions of the rear accommodation housing (5) do not exceed the width and height dimensions of the frame (1).
