REFUELLER WITH VACUUM OPERATION Russian patent published in 2010 - IPC B64F1/28 B64D37/14 B64D37/18 

FIELD: airfield equipment.

SUBSTANCE: invention relates to airfield refuellers. Proposed refueller accommodates vacuum pump (46) communicated, via pipeline, with top of fuel tank (2) (with above-fuel space), said pipeline being furnished with shut-off valve (44) and vacuum metre (45) (pressure indicator, for example barometre) connected thereto. Check valve(47) is arranged on the other side of said vacuum pump. Safety valve (48) is arranged on fuel tank. Vacuum pump (46) cut in and valve (44) open, air is forced from above-fuel space of tank (2) via check valve (47) into atmosphere to reduce pressure in aforesaid space (vacuum). This causes release of gases (oxygen, nitrogen) dissolved in fuel. Fuel with no gases is pumped from refueller fuel tank into aircraft fuel tanks.

EFFECT: expanded performances.
