  "textContent": "An injection nozzle for an internal combustion engine has valve means (22, 80) moveable within a bore (24) of a nozzle body (26), the valve means (22, 80) having a first seat (36, 82) and a second seat (40, 102), both being engageable with a seating surface (28), which has a seat cone angle (&thetas;S), to control fuel delivery through a nozzle outlet (30). The first seat (36, 82) controls delivery of fuel from a first supply chamber (38) to a delivery chamber (34) and the second seat (40, 102) controls delivery of fuel from a second supply chamber (42) to the delivery chamber (34), the second supply chamber (42) being in communication with the first supply chamber (38) by way of a flow path (46, 54; 92, 94) defined within the valve member (22, 80). By virtue of the provision of the first and second valve seats (36, 82; 40, 102), the flow path (54, 46; 92, 94) and the delivery chamber (34), the injection nozzle exhibits improved fuel delivery characteristics.",
