Publication number: 20230022358Abstract: The invention relates to a fuel injector for injecting fuel under high pressure, comprising a housing (1) equipped with a nozzle needle (10) which can be moved in a longitudinal direction and a seal surface (11) of which opens and closes one or more injection openings (13), fuel being injectable via said injection openings. A control chamber (20) which can be filled with fuel exerts a hydraulic pressure onto the nozzle needle (10) in the closing direction thereof, wherein the pressure in the control chamber (20) can be influenced by a control valve (22) in that the control valve (22) opens and closes a hydraulic connection between the control chamber (20) and a low-pressure chamber (21). The control valve (22) comprises a solenoid armature (23) which interacts with a control valve seat (26) in order to open and close the hydraulic connection, said solenoid armature (23) being radially guided in the housing (1) on the exterior (33) of the solenoid armature.Type: ApplicationFiled: December 1, 2020Publication date: January 26, 2023Inventor: Gerhard Girlinger

Patent number: 10415523Abstract: Fuel injection valve having a magnet armature (18) which interacts with a valve seat (19), which is formed on a valve piece (15), in order to open and close an outflow opening (20), wherein the magnet armature (18) can be moved away from the valve seat (19) by an electromagnet (24). A valve piece (15) delimits a control chamber (12), wherein the outflow opening (20) opens into the control chamber (12), and the control chamber (12) can be charged with fuel at high pressure that exerts a hydraulic force on the valve piece (15). Between the magnet armature (18) and the valve piece (15), there is arranged a bracing element (30) which is preloaded against the valve piece (15) and which exerts a force on the valve piece (15) in the region of the outflow opening (20) in the direction of the control chamber (12).Type: GrantFiled: October 24, 2017Date of Patent: September 17, 2019Assignee: Robert Bosch GmbHInventors: Dieter Blatterer, Gerhard Girlinger, Roland Mitter

Patent number: 10090091Abstract: The invention relates to a magnet assembly for a solenoid valve, comprising a magnetic core (3), composed of at least two core elements (1, 2), and a magnetic coil (4), said magnetic core being connected in an annular recess (5) of a core element (1). According to the invention, the recess (5) on the side of a terminal surface (6) which forms the core element (1), is closed in a media-tight manner via a web portion (7). The invention further relates to a solenoid valve comprising such a magnet assembly.Type: GrantFiled: November 28, 2014Date of Patent: October 2, 2018Assignee: Robert Bosch GmbHInventor: Gerhard Girlinger

Patent number: 8608093Abstract: The invention relates to a fuel injector for the operation of an internal combustion engine, having an injector body. An inlet bore of the injector body connects a conical pressure connection to a valve chamber for supplying highly pressurized fuel. The valve chamber is placed along a longitudinal center axis of the injector body and above a nozzle needle. According to the invention, the inlet bore further has a fan-shaped contour starting at the conical pressure connection along the extension thereof, the contour having a fan angle and a variable cross-section in the shape similar to an elongated hole.Type: GrantFiled: May 15, 2009Date of Patent: December 17, 2013Assignee: Robert Bosch GmbHInventors: Gerhard Girlinger, Marcela Haberlova, Arthur Eberhart

Patent number: 6488220Abstract: The fuel injection valve is in particular a component of a reservoir fuel injection system and has a valve body and an electric control valve that controls the pressure which prevails in a control pressure chamber and acts at least indirectly on an injection valve member in its closing direction, wherein the control pressure chamber is connected to a high-pressure fuel source and can be connected by the control valve to a discharge chamber in order to open at least one injection opening. The control pressure chamber is embodied in a sleeve-shaped section of an insert piece inserted into the valve body and is connected to an inlet bore in the valve body by means of an annular chamber encompassing the section and a connecting bore provided in the valve body. The connecting bore intersects the inlet bore at an obtuse angle (&agr;) in a region that is offset from the annular chamber in the direction of the longitudinal axis of the valve body.Type: GrantFiled: April 4, 2001Date of Patent: December 3, 2002Assignee: Robert Bosch GmbHInventors: Gerhard Girlinger, Manfred Hackl, Stefan Reisinger
