spill valve meaning in Hindi

Examples

1. The controlled part of the injector is a solenoid-operated spill valve.
2. Pressure control was achieved by means of an adjustable pump discharge stroke and a " spill valve ".
3. At a critical value, this diaphragm causes another spill valve to open and bleed away the fuel flow.
4. In this case, the chamber within the FCU will expand which causes the spill valve to bleed more fuel.
5. When the solenoid is energized, the spill valve closes, and the fuel is forced through the spray tip into the cylinder.
6. This causes the pump to deliver less fuel until the opposing chamber pressure is equivalent to the air pressure and the spill valve goes back to its position.
7. The pressure is transmitted ( because of a back-pressure valve i . e . no air gaps in fuel flow ) which closes the FCU spill valves ( as they are commonly called ) which then increases the pressure and causes a higher flow rate.
