Abstract
The invention relates to a metering valve () for a gaseous medium, in particular for a gaseous fuel, comprising a preferably planar valve seat element () having at least one flow-through opening () for the gaseous medium, a closing element () movable in a stroke-like manner and interacting in a sealing manner with the valve seat element () in order to release and close the at least one flow-through opening (), and a corrugated or folding bellows () connected to the closing element () for delimiting a compensation space (), which is connected to a pressure space () via a recess () formed in the closing element () so that the same gas pressure prevails in both spaces () irrespective of the switched position of the metering valve (). According to the invention, the compensation space () is arranged on the side of the closing element () facing the valve seat element () and is delimited in the axial direction by a pressure surface () which is formed on the closing element () or on a component () connected to the closing element (), in particular a flange component.
