Apparatus for cooling a fuel injector

A heat transfer assembly for a solenoid operated valve assembly, comprising:

• a housing configured to contain at least a portion of the solenoid operated valve assembly, the housing formed of a first material having a first thermal conductivity value;
• and
• a heat transfer element attached to the housing, and situated atop of the housing in an end-to-end planar facing relationship therewith, the heat transfer element formed of a second material having a second thermal conductivity value, the second thermal conductivity value being greater than the first thermal conductivity value;
• wherein the heat transfer element is axially arranged relative to the housing along an axis of the solenoid operated valve assembly.

A machine, comprising:

• an engine configured to generate a power output and including at least one combustion chamber;
• and
• a fuel injector configured to inject fuel into the at least one combustion chamber, the fuel injector including:
• a nozzle portion;
• a solenoid operated valve assembly configured to control a flow of fuel to the nozzle portion;
• a housing, at least a portion of the solenoid operated valve assembly disposed in the housing, the housing formed of a first material having a first thermal conductivity value;
• and
• a heat transfer element associated with the solenoid operated valve assembly, the heat transfer element attached to the housing, and situated atop of the housing in an end-to-end planar facing relationship therewith, the heat transfer element formed of a second material having a second thermal conductivity value, the second thermal conductivity value being greater than the first thermal conductivity value.
