  "textContent": "The valve has a valve sealing surface cooperating with a valve seat (7) for opening and closing an injection opening (10). A pressure chamber (5) is filled with fuel under injection pressure, and hydraulic forces are developed on a valve needle (8) and are raised with contact of the valve needle on the valve seat. A bolt extension (13) is formed at the valve needle and opposite to the valve seat surface. The bolt extension is projected into a low pressure chamber (18) and is connected with a mechanical coupler (20). Opening force is exerted on the valve needle by the coupler.",
