Beschreibung
Zusammenfassung:	A fuel injection nozzle (14) has a tubular body (20) adapted to receive fuel, a tubular seat member (24) mounted to the body (20), the seat member (24) having an opening (26) for discharging fuel and a valve seat (28) surrounding the opening (26), a poppet valve member (30) engageable with the valve seat (28) to interrupt fuel flow through the opening (26), and an extension spring (32) anchored to the body (20) and to the valve member (30) and biasing the valve member (30) to engage the valve seat (28). The extension spring (32) is a helically-coiled spring with each coil lying close to the adjacent coils and with the coils at one end (44) overlying an end (46) of the body (20) to anchor the spring (32) to the body (20) and to cause fuel flowing through the nozzle (14) to pass between the coils of the spring (32); the spring (32) thereby acts as a filter for fuel to be discharged by the nozzle (14).
