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.

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
