Patent number: 11359589Abstract: A valve for metering a fluid is described, which is used, in particular, as a fuel injector for internal combustion engines, including an electromagnetic actuator and a valve needle actuatable by the actuator, an armature of the actuator being guided on valve needle, a stop element which limits a movement of the armature relative to the valve needle being situated on the valve needle, and the armature including a spring receptacle which is open toward the stop element and in which a spring supported on the stop element is inserted. The valve needle is guided via the armature and/or the stop element along a longitudinal axis of a housing. Furthermore, as viewed along the longitudinal axis, a length of the spring receptacle is smaller than a spring length of the spring in the non-actuated initial state.Type: GrantFiled: October 19, 2017Date of Patent: June 14, 2022Assignee: Robert Bosch GmbHInventors: Murat Ucal, Andreas Glaser, Axel Heinstein, Christian Suenkel, Frank Mueller, Joerg Abel, Marcel Behringer, Martin Buehner, Matthias Boee, Norbert Redlich, Peter Schramm, Stefan Cerny

Patent number: 10738748Abstract: A fluid metering valve includes a valve needle that is actuatable by an electromagnetic actuator that includes an armature guided on and along a longitudinal axis of the valve needle with a movement limited by a stop surface on the valve needle. A projection of an edge of the stop surface extends into a projection plane, perpendicular to the longitudinal axis and at which the armature and stop surface are in contact temporarily during operation, through an opening of a conduit of the armature, dividing the opening into an inner surface on one side of the projection and an outer surface on the other side of the projection. A fluid exchange between inside and outside of an area between the stop surface and armature is via a path through the inner surface, conduit, and outer surface when the armature is in contact with the stop surface at the projection plane.Type: GrantFiled: June 21, 2017Date of Patent: August 11, 2020Assignee: Robert Bosch GmbHInventors: Nico Herrmann, Andreas Schaad, Joerg Abel, Juergen Maier, Martin Buehner, Matthias Boee, Olaf Schoenrock, Philipp Rogler, Stefan Cerny

Patent number: 10711750Abstract: A valve for metering a fluid. An armature of the electromagnetic actuator is movable along a longitudinal axis of a valve needle, the movement of the armature relative to the valve needle being limited by a stop surface on the valve needle. The armature has a passage channel. The stop surface is on a stop element. The stop element and the armature are such that during operation there always remains an intermediate space, adjoining the valve needle, between the stop element and an end face of the armature facing the stop element. The stop surface lies, in a contact region, on the end surface of the armature facing the stop element when the armature and the stop surface come into contact during operation, the contact region being situated between the intermediate space and an opening of the passage channel when the armature and the stop surface come into contact.Type: GrantFiled: June 21, 2017Date of Patent: July 14, 2020Assignee: Robert Bosch GmbHInventors: Andreas Schaad, Joerg Abel, Juergen Maier, Martin Buehner, Matthias Boee, Olaf Schoenrock, Philipp Rogler, Stefan Cerny

Publication number: 20180195477Abstract: A valve for metering a fluid, the valve preferably being designed as a fuel injector for internal combustion engines. The valve includes an electromagnetic actuator and a valve needle that is actuatable by the actuator. The valve needle is used for actuating a valve closing body that cooperates with a valve seat surface to form a sealing seat. An armature of the actuator includes a through opening through which the valve needle extends. An annular gap is formed between an inner wall of a housing part and an outer side of the armature. A movable damping element that may have a partial ring shape is situated on the annular gap. The movable damping element is actuatable by a magnetic field that is generated by the actuator. The dynamics of the armature may thus be advantageously influenced in order to in particular reduce an armature bounce.Type: ApplicationFiled: June 17, 2016Publication date: July 12, 2018Inventors: Andreas SCHAAD, Joerg ABEL, Juergen Maier, Martin Buehner, Matthias Boee, Olaf Schoenrock, Philipp Rogler, Stefan Cerny
