Automated nozzles for cryogenic fluid transfer

A nozzle for coupling and providing fluid to a receptacle, the nozzle comprising:

• a flow body defining a chamber for fluid flow and including a front end and a back end;
• a rotating sleeve configured to rotate about the front end of the flow body, wherein the rotating sleeve includes:
• a coupling end adjacent the front end of the flow body and defining one or more cam slots, wherein the one or more cam slots are configured to slidably receive respective one or more teeth of the receptacle as the rotating sleeve is rotated from an unlocked position to a locked position;
• and
• an actuator end defining a plurality of cutouts, wherein the actuator end includes a plurality of helical guide rails, wherein each of the plurality of helical guide rails is located at an innermost wall defining a respective one of the plurality of cutouts;
• and
• a plurality of locking/unlocking actuators each of which includes:
• an actuator housing fixed relative to the flow body;
• and
• a shaft extending into a respective one of the plurality of cutouts, wherein the shaft is configured to engage and push against a respective one of the plurality of helical guide rails to cause the rotating sleeve to rotate between the unlocked position and the locked position.
