Abstract
A fueling nozzle for pressurized fuel systems having a body connectable to a tank inlet. The body includes an axially displaceable valve movable between a closed retracted position and an extended open position. Connection of the body to the tank inlet occurs upon rotation of the connection sleeve and positioning of the valve is achieved by a rotatable cam sleeve having a cam slot in which a valve-mounted follower is located. An interlock senses mounting of the body on the tank inlet permitting rotation of the connection sleeve in a locking direction and upon the connection sleeve being fully rotated to a locked condition a second interlock permits rotation of the cam sleeve and valve movement from the closed to the open position. The nozzle is characterized by reduced flow resistance characteristics and safe operation.
