Abstract: A low-emission nozzle and receptacle coupling for cryogenic fluid is disclosed. An example nozzle includes a body including a front end and a back end and defining a chamber through which the cryogenic fluid is to flow to the receptacle. The nozzle includes a shaft having a first end and a second end. The shaft is housed within and slidably extending through the chamber. The nozzle includes a poppet coupled to the first end of the shaft and an actuator including a stem coupled to the second end of the shaft. The stem is configured to linearly actuate to cause the shaft and the poppet to linearly actuate. The nozzle includes a coupling assembly coupling the actuator to the back end of the body. The coupling assembly includes insulating material to thermally isolate the actuator from the chamber through which the cryogenic fluid is to flow.

Abstract: Methods and apparatus are disclosed for a low-emission nozzle and receptacle coupling for cryogenic fluid. An example nozzle includes a body defining a chamber through which cryogenic fluid is to flow. The body includes an outer shell that includes an outer shell surface. The nozzle includes a locking assembly configured to securely couple the nozzle to a receptacle. The locking assembly includes an inner sleeve fixedly coupled to the outer shell surface and an outer sleeve extending over and rotatably coupled to the inner sleeve. One or more locking teeth are fixedly coupled to the outer sleeve and configured to be slidably received by respective one or more coupling slots of the receptacle. The one or more locking teeth are configured to rotatably slide within the respective one or more coupling slots to couple the nozzle to the receptacle as the outer sleeve rotates relative to the inner sleeve.

Abstract: A combination valve for pressure building and final-line gas regulation is disclosed. An example valve includes a body defining a first tank port and a second tank port, an outlet port, and a linking chamber fluidly connected to the second tank port. The valve includes a first piston diaphragm at least partially defining a first pressure cavity fluidly connected to the first tank port and a first plug operatively connected to the first piston diaphragm. The first pressure cavity is fluidly connected to the linking chamber when the first plug is in an open position. The valve includes a second piston diaphragm at least partially defining a second pressure cavity fluidly connected to the outlet port and a second plug operatively connected to the second piston diaphragm. The second pressure cavity is fluidly connected to the linking chamber when the second plug is in an open position.
