They are essentially vane-type pumps that have bored passages in the center of the pump, allowing a back-and-forth motion to pump the fuel rather than a full revolution of the vanes as is common in electrically driven or engine-driven vane-type pumps. The Technology Leader In Aircraft Engine-Driven Fuel Pumps. The relief pressure is set via the pressure adjustment screw which tensions the relief valve spring. Any fuel in chamber C is forced through the small check valve in the center of the plunger and into chamber D. When positioned between the solenoid, the plunger is far enough away from the magnet that it no longer attracts it, and the pivot allows the contacts to open. Industrial Coatings, Platings and Insulators, Business & General Aviation Service Center Tools, Software & Database Services (ASDS, NavDB, TerrDB). 1 - 15 This can be a tube in which a shutoff valve is located so the pump can be changed without draining the tank.
