Abstract: A programmable diesel fuel injector that increases frequency response and control precision over desired fuel flow rates throughout each injection event. All valve frequency and motional requirements are met by a compensated direct drive, which is enabled by the durable capability of a rare earth alloy to lengthen in a magnetic field. A continuously variable electrical input waveform is predetermined to result in the desired fuel injection rate shape. A magnetostrictive transducer converts voltage and current into continuously variable force and displacement of a master piston acting upon fuel within a closed chamber. A slave piston responds to the fuel pressure changes within the closed chamber and acts upon the spool of a spool valve to eject fuel.

Abstract: A piezo injector with an actuator chamber, in which a piezo actuator is arranged, includes an upper section (the injector body) and a lower section (the nozzle body). The piezo injector also has a control piston bore formed in the nozzle body, wherein a control sleeve, in which a control piston is received, is arranged in the control piston bore. The control sleeve seals against an intermediate plate with a first front face facing the piezo actuator. The control piston has a first side facing the piezo actuator, wherein the first front face of the control piston and the section of the control sleeve facing the piezo actuator form a first control chamber.

Abstract: A fluid injector has a solid state actuator and a control piston unit arranged in a recess of an injector body. A transmission pin mechanically couples the actuator to the control piston unit. A first control chamber, coupled hydraulically to a second control chamber, is delimited by the control piston unit and the injector body. A control piston of the control piston unit has an end surface that is coupled to the transmission pin and which delimits the first control chamber. The control piston unit has a control sleeve arranged coaxially with the control piston and an inwardly directed projection that provides a driving coupling between the control piston and the control sleeve after a predefined control stroke of the control piston. The driving coupling results in the control piston influencing a free volume of the first control chamber during an axial movement of the control piston.

Abstract: A fuel injection device injecting a fuel from an injection hole to a combustion chamber of an internal combustion engine includes a valve body including a fuel passage through which the fuel flows to the injection hole and a seat portion facing the fuel passage, a valve member moving in the valve body in an axial direction of the valve body and opening and closing the injection hole by being removed from and seated on the seat portion, a dividing member defining a pressure control chamber placed at a position opposite to the injection hole with respect to the valve member, and an outer peripheral member surrounding an exterior of an outer periphery of the dividing member. The pressure control chamber controls a movement of the valve member by a pressure of the fuel that is introduced. The outer peripheral member and the valve body constitute the fuel passage.

Abstract: The invention relates to a fuel injector having an injector housing which has a high-pressure fuel connection which is connected outside the injector housing to a central high-pressure fuel source and inside the injector housing to a pressure space. From the fuel injector highly pressurized fuel is injected into a combustion chamber of an internal combustion engine as a function of the pressure in a control space when a nozzle needle opens In order to provide a fuel injector which can be manufactured inexpensively, the pressure in the control space is controlled directly by a magnetic actuator.
