Abstract
A pressurized fluid dispensing nozzle (110') such as for LPG is screw-threadedly engageable with a tank inlet (192) such as on a vehicle. A sealing sleeve (154) carrying a nose piece (140') is biassed into abutment with a gasket (194) on a seal face (196) of the tank inlet and is urged rearwardly by the abutment. The sealing sleeve (154) is slidably mounted on a sealing member (136') which is urged rearwardly with the sealing sleeve (154) into a valve actuating condition. A trigger (118') is actuated to open a valve assembly (120') by shifting the valve assembly forwardly to bring a valve body (126') into abutment with an actuator (132') on the sealing member (136) which lifts the valve body off a valve seat (128'). The pressurized fluid passes along a passage (146') through the sealing member (136') to be dispensed but part of it enters a chamber (150) through ports (134'). The pressurized fluid in the chamber (150) acts on the sealing sleeve (154) to drive it into sealing engagement with the tank inlet gasket (194) or, if the gasket is missing, with the seal face (196).
