| 发明名称 | Poppet valve | ||
| 摘要 | 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. | ||

| 主权项 | 1. A valve comprising: a first duct; 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, wherein 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; and a connecting portion of the second duct, wherein the connecting portion comprises a flat wall faceing the seat, wherein the narrow space is left between the flat wall facing the seat and the valve disk in the open position. | ||
