| 摘要 |
A metallic spray nozzle having a counterbore from one side thereof into which an insert to control the spray is located and retained by way of a retaining lip formed by deformation of the outer periphery of the counterbore. This deformation can be toward an axis of the nozzle or, alternatively, this deformation can subsequently direct the tip of the periphery outwards at its extremity such that flow into the counterbore is smooth. An O-ring or other sealing membrane is provided between a locating shoulder in the nozzle body and the insert, and an insert shield between the insert and the retaining lip.
