Auto Shut Off Fuel Nozzle designed by ideal styles required by today's customers. It is small, light, and easy to use. At the same time, it is well-manufactured, durable and reliable. It is applicable for filling ready-made diesel oil, kerosene, and gasoline. 

Small aluminum gun body: It is light and easy to operate with a unique and original appearance. Foam and static electricity are reduced due to pressure casting.

Normally open gear is easy to operate all around: It is simple and convenient for customers to configure three different types of flow speeds.

Easy-replaced spout: It only needs to remove the screws connected to the nozzle and replace a new one, so the self-sealing performance of the nozzle can renew as soon as possible. 
Gun body casting is optional for: low-pressure casting, and pressure casting.

When oiling, the switch rises and the mandril opens the master valve to let pressure oil flow into its lower chamber. The pressure oil applies pressure on the skew valve and opens it with oil 

streaming into the oiled container through the nozzle. In the flow of oil, the air in the cavity behind the skew valve is carried away. When the container is not full of oil,  the carried-away air is 

compensated by that from the windpipe and the windpipe nozzle. 

The nozzle is not self-sealing. When the container is filled with oil, the air hole is blocked up by the oil, and the air can not be compensated. Negative pressure emerges after the air in the cavity is taken away. At this time, the diaphragm distorts upward and the diaphragm axis moves with it. Then the stopping steel beads slide toward the center and the axis falls. Without the balance of the fixed pivot point, the master valve automatically seals under the pressure of the spring. It plays the role of self-sealing.
