Invention herewith described refers to the spring ball valve for fuel dispensing nozzle which includes the body (1) of the nozzle to which there is attached the fuel-dispensing pipe (5) within which there is the diaphragm assembly for activation-deactivation of the nozzle by the initiation of the handle (3), and at the back there is attached the connector (4). In the inner part of the dispensing pipe (5) there is fastened the holder (6) of the spring (7), and within the the spring (7) there is inserted the ball (8). When the fuel nozzle is in the non-dispensing position the spring ball valve is closed, preventing leakage of fuel from the nozzle. When the nozzle is in the pouring position, the spring ball valve is opened allowing the pouring of fuel into the tank.
