AUTOMATIC NOZZLE (MAGANEX)

Key Components:

1. Nozzle Body: The main structure that houses the various components.
2. Trigger Handle: The part the user squeezes to start the fuel flow.
3. Spout: The tube inserted into the vehicle’s fuel tank.
4. Venturi Tube: A tube inside the nozzle that plays a crucial role in the automatic shutoff mechanism.
5. Check Valve: Controls the flow of fuel into the spout.
6. Diaphragm: Part of the automatic shutoff system that responds to changes in pressure.
7. Lever or Latch: Holds the trigger handle in place when activated, so the user doesn’t have to continuously squeeze the handle.

How It Works:

1. Start of Fueling: The user inserts the spout into the vehicle’s fuel tank and squeezes the trigger handle, opening the check valve and allowing fuel to flow.
2. Fuel Flow: Fuel flows through the nozzle body, through the Venturi tube, and out the spout into the vehicle’s tank.
3. Air Pressure and Vacuum: As fuel flows, air is drawn through a small hole in the spout (connected to the Venturi tube), creating a vacuum.
4. Fuel Level Detection: When the fuel level in the vehicle’s tank reaches the spout, it blocks the hole, disrupting the air flow and causing a change in pressure.
5. Automatic Shutoff: The change in pressure causes the diaphragm to move, triggering the check valve to close, which stops the fuel flow immediately.

Benefits:

• Safety: Prevents overfilling and reduces the risk of spills and accidents.
• Convenience: Allows users to fuel their vehicles without having to manually stop the flow when the tank is full.
• Efficiency: Ensures a clean and precise fueling process, minimizing fuel waste.

Maintenance and Care:

• Regular Inspections: Ensure all components are in good working condition.
• Cleanliness: Keep the nozzle clean to prevent blockages and ensure smooth operation.
• Repairs: Address any wear and tear promptly to maintain functionality and safety.

Automatic petrol nozzles are a crucial part of modern fueling stations, enhancing both safety and convenience for users.
