Abstract
Ventilation systems and gasper valves for ventilating passenger compartments of aircraft are disclosed herein. The ventilation system includes, but is not limited to, an air supply conduit and a gasper valve. The gasper valve includes a poppet and an annular nozzle. The poppet is configured to move between a closed position and an open position and defines a sealing surface. The annular nozzle has a nozzle throat opposing the sealing surface of the poppet. At least one of the sealing surface and the nozzle throat comprises a flexible material configured to at least partially deform in the closed position to restrict air leakage between the poppet and the annular nozzle.
