摘要： A common rail single fluid injection system includes fuel injectors ramp shaped injection curves at both the front and back ends of an injection event. This is accomplished by including a check speed control device fixed in position within the check control chamber of a fuel injector. The check speed control device controls the speed of a check by restricting fuel flowing into and out of the check control chamber.

摘要： A fuel injector for an internal-combustion engine comprises an injector body and an injection-control valve, which in turn comprises: an open/close element; an elastic thrust element for pushing the open/close element; and a solenoid actuator, which can be actuated for exerting an action countering the thrust exerted by the elastic element. The solenoid actuator is formed by a monolithic assembly obtained in a mould, in which there is injected, on a core and a coil coupled to one another, a plastic material, which defines, once it has solidified, a body for insulation of the core from the injector body and which forms, once it has solidified, a monolithic assembly with the core and the coil.

摘要： An injector for an injection system is provided, including a first opening, a second opening, an open position and a closed position. The first opening is for spraying the fluid out of the injector, and the second opening is for allowing the fluid to exit the injector. When the injector is in the open position, the injector sprays the fluid from the first opening and the flow of the fluid to the second opening is substantially blocked. When the injector is in the closed position the injector allows the fluid to exit the injector from the second opening. The injector substantially blocks the spray of the fluid from the first opening when the injector is in the closed position.

摘要： The invention relates to a fuel injector 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, which can be adjusted between an open position and a closed position. A first part and a second part of the injection valve element are coupled to one another via a hydraulic coupler, which is bounded radially by a first guide for the first part and by a second guide for the second part. According to the invention, at least some sections of the first and the second guide are surrounded at their outer radii by fuel under high pressure, and the pressure realized in the hydraulic coupler is lower than the pressure radially outside the guides.

摘要： A metering servovalve for a fuel injector of an internal combustion engine has an electro-actuator and a fixed valve body, which defines a control chamber communicating with an inlet and with an outlet channel. The outlet channel has at least one calibrated restriction and exits through the lateral surface of an axial stem, on which a sleeve slides, in a substantially fluid-tight manner, to open/close the outlet channel and so vary the pressure in the control chamber. The outlet channel is closed by an end portion of the sleeve that is elastically deformable in a radially outward direction, under the thrust of the fuel pressure, to increase the diameter at which the seal against the valve body is formed, with respect to a non-deformed state, and to generate an axial unbalancing force on the sleeve upon opening when the outlet channel is closed.

摘要： The invention relates to an injector for injecting fuel into a combustion chamber of an internal combustion engine. According to the invention, an injection valve member, which opens or closes at least one injection opening, is controlled by a control valve. The control valve opens or closes a connection from a control chamber into a fuel return line by the positioning of a closing element in a seat or by the opening of the seat. A bore is embodied in the closing element, and a pin is received in the bore. The diameter of the bore essentially corresponds to the diameter of the seat. The pin is supported on one side against a pressure rod, against a spring seat, or against the injector housing.
