Abstract
A ventilation air valve assembly (10) for use in aircraft or similar contexts is provided which may be selectively opened and oriented for directing desired quantities of ventilation air in desired directions. The valve assembly (10) includes a tubular valve body (12) presenting an apertured, flattened lowermost end wall (40) together with an internal valve member (14) in the form of an elongated shank having a bottom surface (46) and a marginal sealing surface (48). In the valve-closed position of the assembly (10), the sealing surface (48) engages a correspondingly configured internal surface of the body (12) in order to prevent air flow through the body (12). Moreover, in the valve-closed position, the lower surface of the valve assembly (10) is flat, essentially flush, and presents no dirt-collecting recesses.
