Continuous particle emitting?

Hey guys,
I want to create a certain paticle System in cascade.
No matter what settings I try the particles always dissapears after a while and then the particle System starts emitting again. I want it to emmit continuous, seemingly forever the same.
I’m a beginner and don’t get what paramenters influence this. Tried with different particle values. I guess “Lifetime”, “spawn rate”, “rate scale”, “duration”, possibly “Max draw count” could all play a factor?

I noticed this: No matter what values I change the first number in the viewer always stays at 1000/2000 the second number (2000) changes when I change parameters, but the first never goes higher…

Please help <3 would be awsome! thanks in advance
