摘要： A dual-fuel fuel injector, having: a first nozzle needle for discharge of liquid fuel via a first nozzle arrangement; and a multiplicity of second nozzle needles, arranged around the first nozzle needle and controlled in terms of axial stroke, for discharge of gaseous fuel via a second nozzle arrangement. Each of the second nozzle needles has for controlling the stroke thereof, a respective control chamber in the injector which can be charged with and relieved of pressure by a control fluid. The dual-fuel fuel injector has an annular duct which can be charged with and relieved of pressure by the control fluid. The dual-fuel fuel injector is designed such that, for controlling the stroke of the second nozzle needles, the control chambers for the second nozzle needles are charged with and relieved of pressure by the control fluid proceeding from the annular duct.

摘要： The invention relates to a combustion gas injector assembly (1) comprising a combustion gas injector (3) having groups (11a,b,c) of combustion gas nozzle openings distributed around the periphery, each group having at least one combustion gas nozzle opening (13), a combustion gas nozzle valve member (9a,b,c) of the combustion gas injector (3), which member can be controlled in the open position and closed position, is associated with each group (11a,b,c) of combustion gas nozzle openings, in order to selectively discharge the combustion gas via the at least one combustion gas nozzle opening (13). The combustion gas injector assembly (1) is configured to control the combustion gas nozzle valve members (9a,b,c) successively with a predetermined time offset (T) into the closed position.

摘要： A dual-fuel injector for a fuel injection device, including: a liquid fuel injector unit with a nozzle needle assigned to a liquid fuel nozzle arrangement of the dual-fuel injector and which is stroke controllable via a first control chamber; and a gas injector unit with a gas nozzle needle assigned to a gas nozzle arrangement of the dual-fuel injector and which is stroke controllable via a second control chamber. Each of the control chambers can be impinged with a control fluid to control the stroke of the respective nozzle needle. The control fluid from both the control chambers can be discharged. The dual-fuel injector has a control fluid reservoir in which discharged control fluid from the first control chamber can be introduced; the dual-fuel injector is configured to impinge the second control chamber with control fluid from the control fluid reservoir for the stroke control of the gas nozzle needle.

摘要： The invention relates to a fuel injector (1) for operating with combustible gas. The fuel injector has a plurality of combustible-gas nozzle valve elements (9), and the stroke of each of the combustible-gas nozzle valve elements can be controlled by means of a paired hydraulic piston control assembly (55) of the fuel injector, wherein each piston control assembly is formed by two control chambers (59, 61) and a piston section (63) on the combustible-gas nozzle valve element paired with the piston control assembly, said piston section separating the control chambers in such a way that their volumes can be varied, and the fuel injector is designed to control the stroke of the combustible-gas nozzle valve elements in tandem using a 3/2-way valve (67), by means of which the hydraulic pressure in one of the two control chambers of the piston control assemblies is controlled.
