Abstract

A fuel valve (1) for injeoting fuel into the cornbustion chamber of a large turbocharged two stroke diesel engine, with a resiliently biased and axially movable valve needle (20) cooperating with a valve seat (22), a plurality of nozzle holes (35) distributed axially and radially over the nozzle (30), an electronically controlled valve connected to a closing chamber in for urging the valve spindle (20) to its seat (22) for alternatively connecting the ciosing charnber to a tank port (18) or to a fuel inlet port (16) It is suggested that Fig. 1 is published with the abstract.

Claims (10)

1. An electronically controlled fuel valve {1) for injecting fuel into the combustion chamber of a large two stroke diesel engine with cross-heads, said fuel valve comprising: a fuel valve housing (10), an nozzle (30), a fuel inlet port (16) for connection to a source (P) of high pressure fuel, a first duct(17) connecting the high pressure fuel inlet port (16) to the nozzle (30), a resiliently biased and axially movable valve needle (20) cooperating with a valve seat (22) and configured to control the flow of fuel from the fuel inlet port (16) to the nozzle (30), whereby lift of the axially movable valve needle (20) allows flow from the fuel inlet port (16) to the nozzle (30), a closing chamber (46) in the valve housing (10) acting on the valve needle (20) with a first effective surface area (Al) and urging the valve needle towards the valve seat (22) when pressurized, an opening chamber (70) in the valve housing (10) acting on the valve needle (20) with a second effective surface area (A2) and urging the valve needle (20) away from the valve seat (22) when pressurized, a control conduit ¢59) connecting the closing chamber to a valve port of an electronically controlled pilot valve, said electronically controlled pilot valve is provided with a valve port connected to said tank port (18) and with a valve port connected to said fuel inlet port (16), said electronically controlled valve being configured to selectively connect said control conduit (59) to said tank port ¢18) or to said fuel inlet port (16) for electronically controlling lift of the valve spindle (20) .

7. A fuel valve (1) according to claim 6, wherein said solenoid valve is a solenoid controlled ball valve (85).
8. A fuel valve (1) according to claim 6, wherein said restricted connection (82) to said tank port (18) is located inside the valve housing.
9. A fuel valve (1) according to claim 2, wherein the spool (53) of said spool valve is connected to an electric actuator that controls the position of the spool (53) .
10. A fuel valve (1) according to claim 1, wherein said nozzle is a nozzle (30) with an axial bore and a closed front and said valve needle moves in unison with a cutoff shaft (40) moving in unison with the valve needle (20) and received axially displaceable in the central bore ¢33) in the nozzle (30) for opening and closing the nozzle holes (35) .
