Abstract
A spray device has a spray nozzle unit (), wherein said spray nozzle unit () comprises a cavity () with an inlet () for receiving a pressurized liquid at an operating pressure and an outlet () for releasing a liquid spray during operation. A spray nozzle body () is fitted sealingly within said cavity (), having a perforated nozzle layer () with at least one spray orifice () that extends between an upstream surface and a down stream surface thereof releasing at least one jet of said liquid spray at said downstream surface of said nozzle layer. The spray nozzle unit () is provided with a pressure safety device () upstream of said spray nozzle body (). Said pressure safety device () comprises a closed burst layer () that closes a fluid pathway between said inlet () and said spray nozzle body () but ruptures once a threshold pressure is exceeded. Said operating pressure exceeds said threshold pressure.
