Abstract

A valve has a first duct and a second duct into which the first duct opens at right angles, thereby defining an intersection that forms a seat for a valve disk that slides in the second duct at right angles to the seat between a closed position and an open position. The valve disk has, facing the seat, a deviation surface of curvilinear profile having a narrow base facing toward the seat and widening away from the seat configured to deflect at right angles to the first duct a gaseous stream originating therefrom.
