  • Patent number: 9180497
    Abstract: The invention relates to a tool for cleaning and/or drying a cavity in a workpiece, such as a hole, in particular a threaded bore. The workpiece has a workpiece adapter. The workpiece adapter includes a workpiece contact surface and has a connector for feeding cleaning medium and/or drying medium. There is an opening in the connection adapter for discharging cleaning medium and/or drying medium containing dirt particles. A nozzle having a nozzle chamber is formed in the workpiece adapter. The connector opens into the nozzle chamber such that a cyclonic flow of the fed cleaning medium and/or drying medium can form in the nozzle and exits the nozzle. The cyclonic flow transports dirt particles from the cavity in the workpiece to the opening for discharging dirt particles and cleaning medium and/or drying medium.

  • Patent number: 9073099
    Abstract: The present invention relates to an installation for cleaning and/or degreasing manufactured parts. The installation applicator includes a first outlet nozzle connected to a device for producing vapor in order to produce a central jet consisting of the pressurized water vapor and a second outlet nozzle surrounding the first nozzle. The second nozzle is connected to a device for producing pressurized air in order to produce a peripheral jet consisting of the pressurized air. The nozzles form a composite treatment jet made of the central jet of pressurized water vapor and the peripheral jet of pressurized air with the peripheral jet surrounding the central jet.

  • Publication number: 20140109939
    Abstract: Nozzle apparatus and methods for treating workpieces are disclosed. An example apparatus includes a nozzle module and a first nozzle chamber disposed within the nozzle module. The first nozzle chamber has a first nozzle opening and is to deliver a relatively high pressure fluid to the first nozzle opening. The example apparatus also includes a second nozzle chamber disposed within the nozzle module and having a second nozzle opening, the second nozzle chamber to deliver a relatively low pressure fluid to a second nozzle opening. A first flow of the low pressure fluid at least partially contacts a second flow of the high pressure fluid. The second flow is directed onto a workpiece.
