Variable angle multi-point injection

A nozzle (200) for injecting liquid includes a nozzle body (202) defining a flow channel (204) and a swirl ante-chamber (206) in fluid communication with the flow channel (204). An injection point orifice (208) is defined in the swirl ante-chamber (206). The flow channel (204) feeds into the swirl a...

More Information
Summary:A nozzle (200) for injecting liquid includes a nozzle body (202) defining a flow channel (204) and a swirl ante-chamber (206) in fluid communication with the flow channel (204). An injection point orifice (208) is defined in the swirl ante-chamber (206). The flow channel (204) feeds into the swirl ante-chamber (206) to impart a tangential flow component on fluids entering the swirl ante-chamber (206) to generate swirl on a spray issuing from the injection point orifice (208). A second flow channel (205) can be included in fluid communication with the swirl ante-chamber (206). The second flow channel (205) feeds into the swirl ante-chamber (206) in cooperation with or in opposition to the first flow channel (204). The first flow channel (204), second flow channel (205), and swirl ante-chamber (206) are configured and adapted to adjust spray angle of a spray issuing from the injection point orifice (208) by varying flow apportionment among the first and second flow channels (205,206).
