ABSTRACT:
A nozzle assembly (26) to be connected to an outlet 24 of a flexible inflatable bag (18, 20) for emitting a stream of air under pressure therethrough to remove fluid from the surface of a vehicle including an elongated body having a first pair of oppositely disposed walls (28, 30) spaced a predetermined distance apart and a second pair of oppositely disposed walls (32, 34) extending between the first pair of walls (28, 30) and spaced from each other a lesser distance than the spacing of the first pair of walls (28, 30). The body further includes an inlet portion (36) defining a first elongated opening (37) and being adapted to be connected to the bag outlet (24) and a nozzle portion (38) defining a second opening (40) having a smaller area than the first opening (37). The nozzle assembly (26) is characterized by including a plurality of webs (42) extending between the second pair of walls (32, 34) and into the nozzle portion (38) for preventing the second pair of walls (32, 34) and the nozzle portion (38) from being forced apart by the pressure of the stream of air passing therethrough while minimally agitating the stream of air.
