Definitions

  • the invention relates to a device for dispensing liquid, in particular by means of a nozzle, with a shut-off valve which has a valve seat which is internally optionally conical and an axial valve needle which is hollow for the radially inner liquid supply and whose end remote from the valve can be connected to a liquid source, optionally with a correspondingly conical one , Tip as valve body, which has at least one bore connected to the cavity of the valve needle with radial component, which opens into an annular space on the valve seat radially between this and a single coaxial, for radially external liquid return, surrounding the valve needle surrounding liquid guide tube, the valve distal end of which a liquid sink can be connected.
  • Tip of the valve needle can be any form of the needle end used as the valve body, since its diameter is in any case small compared to the length of the needle.
  • a plate valve could also be formed by means of a "tip” needle, which bluntly abuts a superficially flat valve seat.
  • valve needle is large i v formed and surrounded by an ink supply tube, the wall of which is provided with bores directed obliquely rearward with respect to the axis, which open into a coaxial return tube which surrounds the ink supply tube radially on the outside and can be connected to an ink sink.
  • the valve needle has a tube, at the axially front end of which an attachment piece forming the needle tip is attached, which is provided with the oblique bore and an axial blind bore which, on the one hand, into the tube the valve needle and on the other hand opens into the oblique bore.
  • oblique bores which are evenly distributed over the circumference of the needle tip and on the one hand offer a relatively low flow resistance when the valve is open and on the other hand cause a deflection of the possibly shared ink flow into the color return.
  • the valve needle can be produced relatively easily and cheaply in the proposed embodiment.
  • valve needle contains a static mixer, which is expediently arranged in the tube of the valve needle and opens into the blind bore of the attachment piece (needle tip).
  • a paint nozzle 2 of an otherwise not shown paint spraying device is screwed with the interposition of an O-ring 4 in the axial, cylindrical extension 6 of a conical valve seat 8, which is fitted into the front end of a radially outer paint guide tube 10 serving the color return.
  • the tube 10 encloses a coaxial, hollow valve needle 12, the conical tip 14 of which forms a valve body which interacts with the valve seat 8 and which is part of an extension piece 16 which is glued into the front end of a radially inner tube 18 which mainly forms the valve needle 12 and serves the ink supply, the latter
  • Cavity contains a static mixer 20 which, as indicated, works without moving parts by the fluids to be mixed, e.g. B.
  • the extension piece 16 has an axial blind bore 22 which opens into the cavity of the tube 18 at the front end of the mixer 20 and from the inner end of which a plurality of oblique, forward-diverging bores 24 extend evenly distributed over the circumference of the needle tip 14, Seen in the direction of flow, open axially in front of the valve 8-14 in an annular space 26 between the valve needle 12 and the color return pipe 10.
  • a radially narrow, long collar 28 of the tube 10 this leads the extension 16 to form a small gap 30, which ensures that the flow resistance for the returned paint is greater than the flow resistance when the valve is open for the paint supplied to the paint spraying device.
  • This device can have a rotating atomizer bell or disc, on the surface of which the paint passes from the nozzle 2.
