- the spring action is expediently carried out by the restoring elements 55 and 56.
- valve seat 60 and the valve shut-off body 61 widen in the direction of flow (e.g. become larger radially, expediently in steps or essentially continuously, e.g. conical) and thus in particular one Form negative valve seat 60.
- This in particular enables the valve shut-off body 61 to be pressed into a closed position in the event of excess pressure (e.g. pressure surges) from the main application agent channel 201, so that the risk of application agent penetrating from the main application agent channel 201 into the Flush valve 50 can be reduced.

- the scavenging air S1 can initially flow through the scavenging valve 50 and when the valve inlet opening for the washing agent line 2 is also opened through the first valve piston 51, the scavenging agent S2 can flow into the flow of the scavenging air S1.
- the invention thus comprises embodiments in which the rinsing agent is supplied at the beginning of the rinsing operation, but also embodiments in which the rinsing air is supplied at the beginning of the rinsing operation. Embodiments are even possible in which the flushing air and the flushing agent are supplied at the same time at the beginning of the flushing operation.
- the flushing valve 50 described with reference to FIGS. B. can be designed as a puffed flush valve (with preferably multiple and / or alternating changes between flushing air, in particular pulsed air, and flushing agent). It should also be mentioned that the flushing valve 50 described with reference to FIGS. 7 to 10 can also be used for other applications. It can therefore also generally be a fluid valve, in particular a paint valve.
- FIG. 11 shows possible switching states of a flushing device 100, in particular of flushing valve 50.
