Definitions

  • the present invention relates to a hose fitting for hydraulic, industrial and air-conditioning applications, having improved tightness characteristics. More particularly, the invention relates to a hose fitting in which the insert is provided so as to provide the improved tightness characteristics indicated above.
  • the type of fitting known as "field attachable” or “reusable” provides for the connection between the collar and the insert by means of a threaded coupling.
  • the aim of the present invention is to provide a hose fitting which is of the type that can be assembled directly in place without particular tools but has a tightness which is substantially equal to that of press-on fittings.
  • an object of the present invention is to provide a hose fitting which is of the type which can be assembled in place or reused and can be applied both to hydraulic applications and in air-conditioning and mobile refrigeration systems thanks to the improved screw coupling characteristics with respect to known types of fittings.
  • Another object of the present invention is to provide a fitting of the type that can be assembled in place or can be reused and can be applied for hydraulic applications, air-conditioning and mobile refrigeration systems.
  • Still another object of the present invention is to provide a fitting which can be assembled in place or reused and is highly reliable, relatively simple to provide and at competitive costs.
  • Figure 1 is a schematic view of the fitting according to the present invention
  • Figure 2 is a schematic view of the insert of the fitting according to the present invention.
  • Figure 3 is a view of a detail of the insert which belongs to the fitting according to the present invention. Ways of carrying out the Invention
  • the fitting according to the present invention generally designated by the reference numeral 1, comprises an insert 2, which is adapted to be inserted within a hose to be connected to another hose, and a collar 3, which is threaded internally and is adapted to be screwed onto the insert 2, which has an external thread 6.
  • the insert 2 is substantially shaped so as to have a first cylindrical portion 2a which is followed by a second conical portion 2b which ends with an additional cylindrical portion 2c.
  • the peculiarity of the invention resides in that the insert 2 is provided with at least one positive groove 5, i.e., at least one protrusion or annular ridge which is arranged circumferentially around the body of the insert.
  • Such positive groove 5 allows the insert 2, once it has been inserted within the hose, to remain firmly engaged within the hose, thus avoiding the slippage of the latter off the insert.
  • the positive groove 5 has a rounded profile, so as to not produce tears within said hose.
  • the positive groove 5 is arranged at the conical portion of the insert.
  • the fitting according to the invention is of the type that can be assembled in place, i.e., without the use of tools, or of the so-called reusable type, by way of the screwing with threading of the collar on the insert.
  • the insert according to the invention despite being of the type that does not require pressing, provides improved assurances of tightness with respect to known types of inserts, due to the presence of at least one positive groove 5 as described above.
  • the fitting according to the invention has a total length which is shorter than that of known types of fittings, since the positive groove or ridge 5 of the insert improves the performance of the insert, allowing to reduce its length with respect to known types of inserts: accordingly, the length of the entire fitting is reduced.
  • the fitting according to the present invention fully achieves the intended aim and objects, since it allows to have a tightness against seepage and leaks which is substantially similar to that of a traditional fitting provided by pressing, but without the need to have a pressing action, and therefore with the advantage of being able to use a fitting with a collar which can be screwed onto the body of the insert.
