Plasma torch

The invention relates to a plasma torch, preferably to a plasma cutting torch, in which a plasma gas PG1 and/or PG2 flows through at least one feed and through a housing of the plasma torch gas up to a nozzle opening. A hollow space connected to the feed(s) is also present within the housing and a valve which opens and closes an opening is arranged at the opening at said hollow space and a leading off of plasma gas PG1 and/or PG2 out of the feed(s) up to the nozzle opening can be achieved in the open state of this valve. 本发明涉及种等离子体焰炬，优选涉及种等离子体切割焰炬，其中等离子气体PG1和/或等离子气体PG2流过至少个进给部、流过所述等离子体焰炬的壳体、到达喷嘴开口。连接到所述进给部的中空空间也存在于所述壳体内，开启和关闭开口的阀布置在所述中空空间的开口处，在该阀的开启状态下，能够实现将离开所述进给部到达所述喷嘴开口的等离子气体PG1和/或等离子气体PG2引导出去。
