초록

A system for controlling lubricant displacement from a machine during turbomachine shutdown sequence includes a motor, a pump, a control valve, and a motor control unit. The motor is selectively energized from a power bus to rotate at a rotational speed and supply a drive force to the pump. The pump, in response to the drive force, draws fluid from a fluid and supplies the fluid to the machine. The control valve is movable between at least a first position, in which the control valve fluidly communicates the pump with a lubrication fluid source, and a se...
