Definitions
- the second expansion stage 12 is shown in FIG. present in the form of a tabular connection, open in its central portion to a transverse wall which is pierced with a slot-shaped orifice 12a.
- the powder arriving at the outlet of the lance 10 enters the hollow central portion of the connector 12 and then opens into the slot 12a in order to create a powder jet at the outlet of the substantially flat lance.
- the slot In order to obtain such a jet, the slot must have dimensions such that its depth P is greater than its height H.
