Abstract
A sprinkler having a valve disc closed by pressure sealing. The valve disc corresponds to a spring elastic annular disc which is subject to uniform loading of acting hydraulic forces and to annular loading of sealing forces of the valve seating on one side, and is supported substantially and centrally at the support surface by a support on the other side. The differential spring rate for annular loading under deflection is smaller or equal to the spring rate of the support measured from the support face to the valve seating.
