CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY
The present application does not claim priority from any other patent application.

TECHNICAL FIELD
The present subject matter described herein, in general, relates to a field of fuel dispensing vehicles. More particularly, the present subject matter relates to an emergency cut-off valve assembly in a mobile fuel dispenser tanker.

BACKGROUND
The concept of mobile fuel dispenser tanker has evolved in the recent days. The mobile fuel dispenser tanker can deliver fuel directly at client location. These mobile fuel dispenser tankers include fuel trucks, fuel tankers, mobile fuel storage units etc. Such mobile fuel dispenser tankers make it easy to transport the fuel from one place to another over a larger distance.
In such mobile fuel dispenser tankers, the fuel delivery occurs through a single or multiple outlet port. Further, great risk is involved of fuel leakage, spraying, ignition, and like during the fuel delivery from the outlet port. Further, it is necessary that quickly closed or opened all the outlet ports at a time remotely when an emergency occurs, so that accidents can be avoided. Further, a driver should be able to close or open all the outlet ports from driver’s cabin so that time required for opening or closing individual outlet port from delivery location can be avoided and thus accidents can be avoided. Further, a means for closing or opening the outlet port should not be electrical as electric sparking may lead to the accident due to ignition and firing of fuel.

Thus, there is a long-standing need of a passive (not using any electricity) emergency cut-off valve assembly in a mobile fuel dispenser tanker configured to close or open the outlet ports remotely .
