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').
