CLAIMS
1. In a vehicle defrost system haing fluid
osciliator means in the dashboard of said vehicle for sweeping a jet of defrost air across the windshield, the improvement wherein said fluid oscillator means has an outlet opening defined by a pair of surfaces converging towards each other and the pivot for the sweeping of said jet is within said oscillator and proximate said outlet opening to thereby reduce the amount of space on said dashboard for issuing defrost air upon said windshield.

2. The invention defined in claim 1 wherein said fluid oscillator is a fluidic oscillator of the type having an interaction, a heated air power nozzle at the upstream end of said chamber and said outlet opening being at the downstream end of said chamber, and the sidewalls of said chamber converge to said outlet opening to form a cross-over type outlet.

3. The invention defined in claim 2 wherein the dimensions of said outlet opening transverse to the longitudinal direction of said vehicle is under about
2 inches.

4. The invention defined in claim 2 wherein there is a driver and a passenger side of said vehicle windshield and said outlet opening is located proximate the center thereof.

5. The invention defined in claim 2 wherein there is a driver side and a passenger side of said vehicle windshield and there are two said fluidic oscillators, the outlet opening of one being centered proximate the center of the driver side and the outlet opening of the other being centered proximate the center of the passenger side.

6. In a vehicle windshield defrost system having fluidic oscillator means in the dashboard of said automobile for sweeping a jet of defrost air across a windshield, said fluidic oscillator means has at least one interaction chamber, a heated air power nozzle at one end of said interaction chamber and a defrost air outlet from the opposite end of said interaction chamber, and sidewalls, the improvement wherein portions of said sidewalls converge to said outlet to form a crossover type outlet and thereby reduce the amount of space on said dashboard for delivering defrost air to said windshield.
