Abstract

An adjustable air outlet nozzle for automobile heating and venting systems in which a spherical hollow nozzle is connected to a surrounding housing lodgement by means of an intermediate gimbal ring and includes a double-clappet valve which is operable by means of a wing knob, through a bevel gear drive. The nozzle shell has an inner wall with an abutment shoulder for the valve clappets and a progressively widening gap for sensitive throttling of the air flow.
