Nozzle combustion shield and sealing member with improved heat transfer capabilities

A heat transfer assembly comprising:

• a bore configured to receive a fuel injector, the bore including:
• a first fluid opening in fluid communication with a first fluid jacket;
• a second fluid opening in fluid communication with a second fluid jacket;
• and
• a fluid outlet positioned within an annular wall of the bore;
• a first valve positioned between the first fluid jacket and the first fluid opening and configured to selectively permit fluid from the first fluid jacket to enter the bore;
• a second valve positioned between the second fluid jacket and the second fluid opening configured to selectively permit fluid from the second fluid jacket to enter the bore, the second valve being movable between an open configuration to permit fluid flow from the second fluid jacket into the bore via the second fluid opening and a closed configuration to prevent fluid flow from the second fluid jacket into the bore;
• wherein the second valve moves from the closed configuration to the open configuration in response to contact with a first section of the fuel injector.

A heat transfer assembly comprising:

• a fuel injector comprising a nozzle;
• a nozzle combustion shield configured to couple to the nozzle of the fuel injector;
• a bore configured to receive the fuel injector, the bore including a fluid opening in fluid communication with a fluid jacket and a fluid outlet positioned within an annular wall of the bore;
• and
• a valve positioned between the fluid jacket and the fluid opening and configured to selectively permit a fluid from the fluid jacket to enter the bore, the valve being movable between an open configuration to permit fluid flow from the fluid jacket into the bore via the fluid opening and a closed configuration to prevent fluid flow from the fluid jacket into the bore;
• wherein the valve moves from the closed configuration to the open configuration in response to contact with a section of the nozzle combustion shield.
