REFUELING TRUCK Russian patent published in 2004 - IPC

FIELD: airfield refueling trucks for filling the flying vehicles.

SUBSTANCE: proposed refueling truck includes fuel pump with hydraulic drive equipped with hydraulic motor which is connected with hydraulic pump by means of regulator. Pressure warning system connected with regulator is built in filling line. Control system ensures manual control of revolutions of hydraulic system from zero to maximum. If pressure of fuel at inlet of on-board pipe union exceeds permissible level, one of warning units set at this level operates and regulator will be changed-over to idle run position when main flow is circulating in closed loop between hydraulic pump and drainage tank. As a result, speed of hydraulic motor will be decreased and pressure will be set within permissible limits.

EFFECT: enhanced safety; extended functional capabilities.
