The second difference between axial and tangential nozzles lies in how the liquid is injected into the nozzle.
If the liquid is injected axially to the spray direction, it is an axial nozzle.
When the liquid is injected tangentially to the spray direction, we call it a tangential nozzle. A duct inside these nozzles tangentially injects the fluid into the turbulence chamber, where the centrifugal force produces a high rotation speed and generates a spray cone. Since these nozzles have a large free passage without a vane, they offer maximum resistance to clogging.
