Beschreibung
Zusammenfassung:	Disclosed is a valve that is particularly useful in a pressure atomizing nozzle of a heating installation and includes a valve housing in which there is a valve seat with an adjoining valve chamber and a flow passage that opens to a housing outlet. In the valve chamber there is provided a spring for resiliently urging the closure member to seat on the valve seat. The valve chamber has a guide section adjacent the valve seat that is of a transverse cross section corresponding to a transverse cross section of the closure member while the housing and closure member provide a free flow passage to the outlet when the closure member is moved axially away from the valve seat at least a preselected axial distance. The valve is of a construction that ensures that fluid can flow through the valve only after a particular desire pressure has been reached, but immediately after the conveying pressure drops below a predetermined value, fluid can no longer reach the housing outlet.
