Abstract
Methods and apparatus are disclosed for a coupling nozzle for cryogenic fluid. An example nozzle comprises a flow body defining a conduit, an inlet, and an outlet. A pneumatic cylinder is configured to slide between an extended position and a contracted position. The pneumatic cylinder is coupled to and configured to actuate the flow body. A locking mechanism is configured to secure the coupling nozzle to a receptacle. A flow control assembly comprises a valve seat fixed to the flow body adjacent the inlet and a plug configured to slide. When the locking mechanism is locked and the pneumatic cylinder actuates to the extended position, the valve seat is to disengage from the plug to open the flow control assembly. When the locking mechanism is locked and the pneumatic cylinder actuates to the contracted position, the valve seat is to engage the plug to close the flow control assembly.
