摘要

The spray nozzle housing (1) contains a turbulence chamber (13) connected to the nozzle opening (5). The opening is tightly sealed by a seal (18,20) resting against the outside of the housing. The seal is pressed against the housing by a cylindrical, hollow pressure body (25) of glass or other material which is flexible at a release temperature. The end of the pressure body facing away from the seal is supported on the part joined to the housing. The pressure body is supported on an adjusting screw (28) or spring.
