Abstract
Abstract A flow outlet structure for an automotive air conditioner which is equipped with a louver having a plurality of movable slats and a fluidic element to cyclically change the direction of flow laterally of the automobile as long as the angle of the slats of the louver are below a predetermined angle. When the slats of the louver takes an angular position greater than the predetermined angle, the flow of cool air in three diversified directions is provided.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
139 words
A flow outlet structure for an automotive air conditioner, comprising: a duct having one end communicable with said air conditioner to receive conditioned air therefrom, and an opposite end; an air outlet coupled with the opposite end of said duct, said air outlet including a fluidic element means having a solenoid valve for urging the flow of conditioned air passing through said air outlet to deflect in a first direction when said solenoid valve is energized and in a second direction when said solenoid valve is not energized; and a louver fitted in the outlet opening and having a plurality of parallel pivotable slats for swingable movement in a direction normal to said first and second directions, said plurality of slats being disposed at a downstream end of said air outlet with respect of the flow of conditioned air.
Claim 2
Dependent Claim
