Abstract

Die Erfindung betrifft ein Schaltventil (10) mit einem Ventilkörper (20), in dem ein Strömungskanal (24) ausgebildet ist, der mit seinem einen Ende in einen Arbeitsraum (42) mündet. In dem Arbeitsraum (42) ist eine Ventilplatte (44) aufgenommen, die zwischen einer Schließstellung und einer Freigabestellung bewegbar ist. Zwischen der Ventilplatte (44) und der Mündung (26) des Strömungskanales (24) ist ein Schließelement (50) angeordnet, das diese verschließt, wenn sich die Ventilplatte (44) in ihrer Schließstellung befindet.

Figure 00000001
The invention relates to a switching valve (10) with a valve body (20), in which a flow channel (24) is formed which opens at one end into a working space (42). A valve plate (44) is received in the working space (42) and can be moved between a closed position and a release position. A closing element (50) is arranged between the valve plate (44) and the mouth (26) of the flow channel (24), which closes it when the valve plate (44) is in its closed position.
