Gas burner with holder for injector inlet to mixing duct - has injector inlet as separate, tubular part, engaging with play mixing duct

摘要

The injector inlet (7) is coaxially aligned with a gas nozzle in a gas distribution tube (2). Its free end section is held in a centring rail coupled to the tube. It is in the form of a separate, tubular part engaging with play the mixing duct (10). Pref. the injection inlet engages a peripheral groove (6) embossed into the sheet metal centring rail (4). The latter may be coupled to the gas distributor by a sheet metal strip (3), parallel to the gas nozzle axis. ADVANTAGE - Precise positioning of each gas nozzle wrt the associated injector inlet.
