• an inner nozzle insert defining an inner flow channel;
• an intermediate nozzle insert disposed around the inner nozzle insert,
• the intermediate nozzle insert and the inner nozzle insert defining an intermediate flow channel;
• and
• an outer nozzle insert disposed around the intermediate nozzle insert,
• the outer nozzle insert and the intermediate nozzle insert defining an outer flow channel,
• the intermediate nozzle insert and the inner nozzle insert cooperating to define an intermediate outlet,
• at least one of the inner nozzle insert and the intermediate nozzle insert further defining at least one aperture disposed upstream from the intermediate outlet, at least one aperture being arranged to fluidly connect with at least one of the inner flow channel and the outer flow channel.
