ABSTRACT:
A spray nozzle comprises a spray nozzle body through which there run an axial passage and a transverse bore to which a cooling fluid outlet injection conduit is connected. The spray nozzle body further comprises a sleeve in the shape of a cylinder of revolution coaxial with the axial passage. The outside diameter of the sleeve is such that it can be force-fitted into the fluid feed orifice of the cylinder, which is also a cylinder of revolution. The outside surface of the sleeve has a smooth or knurled portion. The spray nozzle is simply force-fitted into the cooling fluid feed orifice.
