Abstract

Für ein einfach herzustellendes Einblasventil, das einen hohen Durchström-Massenstrom ermöglicht, eine hohe Dichtheit gewährleistet und einen niedrigen Verschleiß aufweist, ist vorgesehen, dass am Ventilsitz (2) eine der Ventilplatte (3) zugewandte Stirnfläche (20) vorgesehen ist und die zumindest eine Durchströmöffnung (10) in der Stirnfläche (20) mündet, wobei die Mündung (24) der zumindest einen Durchströmöffnung (10) in der Stirnfläche (20) in Form einer offenen Kurve ausgebildet ist, dass an der Stirnfläche (20) eine Dichterhebung (23) vorgesehen ist, die von der Stirnfläche (20) in axialer Richtung in Richtung des Gasvolumens (7) absteht und die Dichterhebung (23) die zumindest eine Durchströmöffnung (10) vollständig umgibt, und dass am Ventilsitz (2) zumindest ein Anschlag (25) vorgesehen ist, der von der Stirnfläche (20) des Ventilsitzes (2) in axialer Richtung eine Anschlaghöhe (HA) in Richtung des Gasvolumen (7) absteht, wobei ein dem Gasvolumen (7) zugewandtes axiales Ende der Dichterhebung (23) um einen vorgegebenen Differenzabstand (D) weiter in das Gasvolumen (7) hineinragt, als ein dem Gasvolumen (7) zugewandtes axiales Ende des Anschlages (25).
