Abstract
A two-component spray nozzle, in particular for die spraying devices, comprising a nozzle inlet end for working medium and blast air as well as a nozzle outlet and, a blast air guiding portion having at least one blast air supply line connectable with a supply member for blast air, and a working medium guiding portion having at least one working medium supply line connectable with a supply mechanism for the working medium.
Claims33
Two-component spray nozzle (40), in particular for die spraying devices (1), comprising:
- a nozzle inlet end (40c1) for working medium and blast air as well as a nozzle outlet end (44i),
- a blast air guiding portion (41) having at least one blast air supply line (42) connectable with supply means (24) for blast air, and
- a working medium guiding portion (44) having at least one working medium supply line (44c/44d) connectable with supply means (22) for working medium,
- characterized in that there is provided at least one blast air channel (45) between the blast air guiding portion (41) and the working medium guiding portion (44), which blast air channel is subsequent to the at least one blast air supply line (42) and extends from the nozzle inlet end (40c1) toward the nozzle outlet end (44i) at an increasing distance to a spraying axis (S) defined by these two ends and in that the at least one working medium supply line (44c/44d) extending in the working medium guiding portion (44) opens into an end portion (46) of the at least one blast air channel (45).
