Abstract

The object of the invention is to provide a new spray head for group release in a fire fighting installation with a high operating pressure. The spray head comprises a spindle element pressed into the inlet of the spray head with such a spring force that the spindle element keeps the inlet closed against the rest pressure of the installation but yields to the operating pressure of the installation.
