ABSTRACT:
A valve for regulating a gas flow has a valve housing with an inlet for the gas to be regulated, an outlet for a regulated gas flow, a valve seat with a valve opening, and a movable sealing part with a controllable shaft, the terminal side of the sealing part making and breaking a seal between the valve seat and the sealing part such that the sealing part closes and opens the valve opening and regulates the gas flow through the valve opening. In order to allow particularly small gas flows to be repeatedly regulated with high precision and a large dynamic, the plane of the terminal side of the sealing part and the plane of the valve seat form a non-zero angle, allowing the terminal side of the sealing part to press against the valve seat, or to detach therefrom, so that the terminal side gradually closes and opens the valve opening. Alternatively a preformed part is attached between the terminal side of the sealing part and the valve seat, this part being arranged obliquely relative to the valve seat and having a surface area which corresponds to at least the surface area of the valve seat. The terminal side of the sealing part is arranged such that it presses the obliquely arranged part against the valve seat, or detaches it therefrom such that the obliquely arranged part gradually closes or opens the valve opening.
