Definitions

  • the annular seat 14 also made of non-magnetic material of great hardness, has a spherical bearing 30 adapted to the dimensional characteristics of the ball, bearing which can be produced by any known machining means but preferably by cold stamping. This gives perfect sealing when the injection pipe is closed by the ball.
  • Figures 5 and 6 illustrate alternative embodiments of the nozzle of the injector of Figure 4, to obtain the output of the vaporization of the fluid in a conical jet.
  • the nozzle 31 inside the seat becomes unnecessary and can be removed.
  • This variant also provides a conical jet but here, the volume located downstream of the helical ramps is lower than in the previous case, which promotes the rotation of the fluid.
  • the manufacture of the washers in any material is very easy to perform and therefore inexpensive.
