Low-emission nozzle and receptacle coupling for cryogenic fluid

A receptacle for coupling to and receiving cryogenic fluid from a nozzle, the receptacle comprising:

• a body including a proximal end and a distal end, the body comprising:
• an outer shell;
• a plurality of interior walls defining a chamber through which the cryogenic fluid is to flow, wherein the plurality of interior walls include:
• an inner interior wall that extends from the proximal end of the body and back toward the distal end of the body in a longitudinal direction;
• a middle interior wall that is connected directly to and extends from a front end of the inner interior wall and back toward the proximal end of the body;
• and
• an outer interior wall that is connected directly to and extends between a back end of the middle interior wall and the distal end of the body,
• wherein the plurality of interior walls extend longitudinally back-and-forth in a zig-zag pattern to define an elongated conduction path between the chamber and the outer shell to impede a heat leak between the chamber and an exterior of the receptacle;
• and
• an insulation layer located radially between the chamber and the outer shell;
• a shaft housed within and slidably extending through the chamber;
• a poppet seat positioned within the chamber;
• and
• a poppet coupled to the shaft, wherein the poppet is configured to engage a nozzle poppet when the receptacle is coupled to the nozzle, wherein the poppet is configured to engage the poppet seat in a closed position, wherein the poppet is configured to disengage from the poppet seat when pushed by the nozzle poppet.
