There is disclosed a high pressure dispensing nozzle for providing cryogenic fuel such as liquid natural gas (LNG) from a source to a filling receptacle, such as on a vehicle. The nozzle has a gun-style nozzle construction and a plurality of jaw members provided near a distal end for locking engagement with the filling receptacle. The nozzle further has a movable internal poppet to establish a fuel passageway through the nozzle for delivery of fuel therethrough. Two different triggers enable separate steps of locking of the nozzle onto the filling receptacle and initiating gas flow for ease of use. The two steps may also me combined and actuated by a single trigger. One nozzle disclosed includes a safety button for dispersing residual gas in the nozzle prior to disengagement to help avoid injury to the user. |
