An accumulator assembly for providing hydraulic fluid to an electrohydrostatic actuator includes an accumulator for containing a supply of hydraulic fluid, the accumulator having an exit port via which hydraulic fluid can flow, in use, to the actuator. The assembly further includes an accumulator refill arrangement fluidly connected to a supply of hydraulic fluid for refilling the accumulator via a fluid line when a level of fluid in the accumulator is below a predetermined value. The accumulator includes a cylinder defining a fluid chamber and an accumulator piston moveable within the cylinder relative to the chamber responsive to the fluid pressure. The refill arrangement includes a spool moveable across the fluid line between an open position, wherein fluid can flow along the fluid line from the supply to the chamber, and a closed position, wherein the spool blocks the flow of fluid from the supply to the chamber.
