Zusammenfassung:A fuel injector assembly comprises a pumping chamber 240 and a piston 10 slidable axially to draw fuel into and force fuel out of the pumping chamber. A fuel inlet passage is provided in the piston via which fuel is delivered into the pumping chamber. A one-way, washer-type inlet valve 11 is mounted in the piston to control flow of fuel into the pumping chamber. The valve comprises a valve seat having a plurality orifices arranged in an annular ring and a moveable valve member engageable with the valve seat to close the apertures in the valve seat, the valve member being annular and having a central aperture through which fluid can flow when the valve is open.
