Abstract

An adjustable outlet nozzle for heating and venting systems of automobiles having a double-wing butterfly valve arranged inside a convex-spherically shaped ring which is universally pivotably supported by a concave-spherically shaped connector housing, the wing flaps of the valve being actuatable by means of a rotatable cross handle and a bevel gear drive, the flanks of the cross handle being axially aligned with a transverse supporting member and with the fully open wing flaps of the valve, to form a smooth air guide through the nozzle.
