ABSTRACT:
A multiple-nozzle head to be exchangeably mounted to jet tubes, in particular of spray cleaning apparatus, comprises a cavity into which issues at the rear a feed aperture opposite to which are mounted on the front end side of the cavity several discharge apertures connected to several preferably different nozzles, at least one freely moving valve sealing element being located in said cavity and by gravity can be moved in front of one of the discharge apertures, each discharge aperture receiving one valve seat, one support ring holding the valve seat, and connected thereto in the direction of flow one jet-aligner which in cross-section is preferably cross-shaped and which joins the nozzle.
The valve seat, support ring and jet-aligner form one integral component and consist either of a sintering material with wear-resistant additives (for instant PTFE compound material with addition of molybdenum-disulfide or graphite) or of a fluorinated, thermoplastically processing synthetic with wear-resistant additives (for instance with addition of molybdenum-disulfide or graphite), or of a crystalline thermoplastic based on a fluorinated polymer (for instance PVDF) or of a crystalline thermoplastic with a lubricant additive (for instance POM-M).
Such a multi-nozzle head is characterized by simple manufacture and assembly. Its size and weight can be kept relatively small.
