Abstract
An electromagnetically actuated gas valve () for gas engines () includes a valve seat () that has at least one flow-through opening () and a corresponding sealing plate (), with the sealing plate being movably arranged and guided essentially perpendicularly relative to the valve seat (), with barrier surfaces () and discharge openings (). The sealing plate () is loaded against the valve seat () by means of a return spring () and can be lifted for the purpose of opening it via a solenoid (). In order to allow for the secure sealing and easy switchability even in the presence of the effect of the combustion chamber pressure, the sealing plate () is arranged on the discharge side of the valve seat () and connected by means of a stamp (), which extends through the valve seat (), with the anchor plate () of the solenoid (). A Venturi tube meter () is arranged on the discharge side after the sealing plate () for the purpose of calibrating the flow-through correction value and for suppressing any dispersions due to manufacturing variations with regard to the effective flow cross-section, and the cross-section of the Venturi tube meter () is smaller than the sum of the effective flow-through cross-sections between valve seat () and opened sealing plate ().
