摘要： The invention relates to a fuel injector (1) and, in particular, to a common-rail injector for injecting fuel into a combustion chamber of an internal combustion engine with a multi-part injection valve element (21), which can be adjusted between an open position and a closed position, wherein a first part (22 ) and a second part (23) of the injection valve element (21) are coupled to one another via a hydraulic coupler (24), which is bounded radially by a first guide (53) for the first part (22) and by a second guide (54) for the second part (23). According to the invention, at least some sections of the first and the second guide (53, 54) are surrounded at their outer radii by fuel under high pressure, and the pressure realized in the hydraulic coupler (24) is lower than the pressure radially outside the guides (53, 54).

The fuel injection system comprises an engine management system (20), a return conduit (17) connected to a low-pressure fuel system (4), and a common rail (6) for storing and supplying a relatively high-pressure fuel to injectors (7). Each injector has a nozzle (11 ) for injecting fuel into the engine, a valve (10) installed between the common rail (6) and the nozzle (11 ), and a spill valve (12) connected by its inlet to the outlet of the valve (10) and by its outlet to the return conduit (17). A first automatic isolating valve (8) is installed between the common rail (6) and the injector (7) and a second automatic isolating valve (18) is installed between the return conduit (17) and the low-pressure fuel system (4).

摘要： The invention relates to an injection nozzle (1) for an internal combustion engine, particularly in a motor vehicle. Said injection nozzle (1) comprises a first nozzle needle (2) for controlling at least one first injection port (5) and a second nozzle needle (3) for controlling at least one second injection port (15). A nozzle chamber (11) can be connected to a high pressure source (28) via a fuel supply line (27). The first nozzle needle (2) is provided with a first pressure stage (12) which is disposed in the nozzle chamber (11) and can be impinged upon therein by an injection pressure that applies an opening force acting in the opening direction (13) to the first nozzle needle (2). In order to improve closing of the first nozzle needle (2), a control chamber (38) is provided which can be connected to the high pressure source (28) via a control line (39). The first nozzle needle (2) encompasses a first control surface (41) which is located in the control chamber (38) and can be impinged upon therein by a control pressure that applies a closing force acting in the closing direction (7) to the first nozzle needle (2). The control line (39) is more severely throttled than the fuel supply line (27).

摘要： 12. A device for generating pressure pulses, comprising a pressure fluid source (7) and a pressure fluid depression (8), a pressure fluid circuit (2), a valve body (3) displaceably located in a chamber (4), a first branch (18) and a second branch (19) of the circuit (2), said branches leaving to opposite sides of the valve body (3), the chamber (4) having an opening (21) on one side of the valve body (3), said opening (21) communicating with the first branch (18) and permitting pressure fluid to flow out of the chamber (4), wherein the valve body (3), under the action of the pressure fluid in the branches (18, 19), is displaceable to a first position in which it closes the opening (21) open for out-flow of the pressure fluid. The device comprises a first valve member (9, 10) arranged to permit or interrupt communication between the chamber (4) and the pressure fluid source (7) through the second branch (19) upstream said chamber (4).

摘要： The invention relates to an injector for high pressure injection of fuel in auto-igniting internal combustion engines. The injector comprises an actuator valve for opening and closing the injector, an injector needle (17) which seals at least one injection opening (18) when the injector is in a closed state, a metering valve (4) producing a hydraulic connection between the actuator valve and the discharge area (6) of the injector, a pressure maintenance device (33) which is used to maintain the pressure required for the metering valve (4), a first line (20) for control amounts (34) flowing via the actuator valve and a second line (43) for control amounts flowing via the metering valve (4). The pressure maintenance device (33) dynamically separates the control amounts (35) from the metering valve from the control amounts (34) from the actuator valve by means of a hydraulic vibration damper.
