Abstract
A spray-suppressant flap for use behind the wheels of a highway vehicle has a laterally centrally located area including forwardly protruding laterally-extending bars, and laterally outwardly located vertically-extending areas including small forwardly protruding members arranged so as to divert liquid flowing laterally from between the bars to flow downwardly. In one variation of the invention the bars are upwardly convexly arcuate. The area including the bars may extend from top to bottom, or only in an upper portion of the flap. Ridges may be provided between the bars to deflect spray toward forwardly-extending surfaces of the bars. An upper marginal portion of the flap may be of dovetail section, so as to fit in a V-shaped downwardly-open channel to mount the flap. The pattern may be used for side skirts as well.
