FLUID DISPENSING NOZZLE

摘要

A fluid dispensing nozzle (200) comprises a handle portion (308), a valve (220) for controlling the dispensing flow of fluid from an inlet hose (222) around which the handle portion extends to an outlet end (224). The valve is actuatable by a lever (218) which causes the valve to be displaced forwardly to bring a valve body (226) into abutment with an actuator (232) when a sealing assembly (248) is displaced rearwardly by engagement with a tank inlet. A connector (242) is mounted for rotation relative to the handle portion and has a screw thread (244) for engagement with the tank inlet by rotation of the connector in one direction. A locking device (322) is provided between the handle portion and the connector and operates when the lever is in its position which opens the valve to prevent manual rotation of the connector relative to the handle portion in the opposite direction but to permit rotation of the handle portion relative to the connector in the opposite direction. The locking device comprises a slidable pawl (340) which is biased by a spring (344) towards an array of recesses (328) in the end face (332) of the connector.
