[ What is claimed is:] [1.]1. A valve assembly for use in discharging air from a portion of a vehicle of the type having a floor, said valve assembly comprising:a housing having a longitudinal axis which forms a first angle with said floor, said first angle having a value;a first member which is disposed within said housing and which includes at least one opening through which air selectively passes; andat least one selectively movable second member which is pivotally coupled to said first member along an axis which forms a second angle with respect to said longitudinal axis, said second angle is an acute angle, being effective to cause said at least one movable second member to operatively and selectively cover said first opening when said value of said first angle is between approximately zero degrees and approximately ninety degrees.
