Distributor for car ventilating air - has equilateral triangular prism with single inner shutter blocking one of three outlets

摘要

The air distributor has a casing (1) in which are holes (7,8,9) each leading to ventilation ducting. A single shutter (10) moves around parallel axes (11,12) connected to it and can have three positions, each blocking one hole. In these positions the axes occupy angled stops (14,15,20) of an equilateral triangular prism. There are bearings for the axes and concentric sliding surfaces (16,17). A control (21,23) is connected to the shutter to move it around one stop, at the same time sliding along the sliding surfaces. The casing is closed by two side cheeks (5).
