Coupling nozzle for cryogenic fluid
Methods and apparatus are disclosed for a coupling nozzle for cryogenic fluid. A nozzle for cryogenic fluid includes a flow body, a flow control assembly, a first linear actuator, and a locking actuator. The flow body defines a conduit. The flow control assembly is at least partially disposed in the conduit of the flow body. The flow control assembly is configured to transition between an open position and a closed position to permit and prevent, respectively, the cryogenic fluid to flow through the flow body. The first linear actuator includes an actuator body and a first shaft. The first shaft is configured to slide between an extended position and a contracted position to transition the flow control assembly between the open position and the closed position, respectively. The locking actuator is for locking the nozzle to a receptacle in an automated manner.
