A fuel injector (1) for a compression ignition internal combustion engine which comprises a fuel injection valve having an injection valve member (5) which is moveable in use, under the influence of fuel pressure within an injection valve member control ch...

A fuel valve (1) for injecting fuel into the combustion 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) distribut...

The pressure amplification device (10) has an inner piston (38) and an outer piston (25) arranged concentric to each other. The pistons are arranged in a housing. The inner piston is arranged in an axially displaceable manner in the outer piston. A control...

The valve (1) has a jet needle (12) actuated by an actuating device (13) e.g. piezoelectric actuator, by using a coupler (14). The coupler includes a valve sleeve (26) guided at a guide flange (31) of a throttle plate (5). The sleeve includes a conical env...

The valve has an actuator sided return (17) that is attached to a control valve sided return (22). The return (17) has a backstroke stop valve (25) for blocking an actuator piston area (8) and is throttled. The actuator piston area interacts with a balanci...

An injector body (B1) is provided with a longitudinal hole (31) eccentrically to the injector body (B1) to install an actuator (3) and a hydraulic power transmission unit (4). A high-pressure fuel passage (1) is disposed in a thick wall portion formed at a...

A control piston (34) guided in longitudinal movement in a valve body (31) comprises a pressure piston section (35) guided in a bush (33) and a control piston section (36) with a sliding seal having a control edge (45). The control piston section is guided...

The high-pressure fuel supply (5) is connected (3) to a valve body (31) of a control valve (30). A control piston (70) moves up and down in the valve body and may be controlled by a switching valve (40). It may control a connection (58) to a chamber (26) u...

The device (1) has a fuel injection valve (10) connected to a high-pressure line and a control valve (30) with a valve body (31) with a piston longitudinally movable in a bore. In a first valve position the piston separates a valve chamber from a return or...
