摘要

The device has a controllable valve (32), where the device is positioned between a high pressure pump and a jet nozzle of a cutting system. An inlet (11) and two flow regions (2, 3) are provided in the device. The flow regions are joined in an admission pipe (12) of the nozzle, where one region is formed as a high pressure region with a switchable valve, and a pressure reducing region comprises a pressure reduction unit (31).
