Patent number: 9371807Abstract: A method and a device for setting an idle stroke of an actuating drive of an injection valve with respect to an actuating element actuated by the actuating drive. The actuating drive is arranged in an injector body and the actuating element is arranged in an actuating-element housing such that it is movable in an axial. An axial stressing force is applied to the injector body and the actuating-element housing such that part of the injector body or actuating-element housing arranged in a force flow path defined the axial stressing force is deformed permanently, until a value of a representative electric variable determined directly or indirectly for the idle stroke of the actuating drive lies in a predefined value range. Further, an injector assembly for an injection valve may include an injector body and/or an actuating-element housing having a contact section elevated in the axial direction.Type: GrantFiled: August 18, 2011Date of Patent: June 21, 2016Assignee: CONTINENTAL AUTOMOTIVE GMBHInventors: Maximilian Kronberger, Hellmut Freudenberg, Robert Schäpers, Matthias Wicke, Stefan Mindl, Wolfgang Wechler

Publication number: 20100018030Abstract: A cylindrical housing has a coaxial opening having a circular cross-section and at least one line having an oval cross-section, extending parallel to a longitudinal axis. To produce the cylindrical housing, the coaxial opening is produced with a large diameter having at least one bore with a small diameter extending parallel to the opening in a cylindrical blank, and subsequently a mandrel is inserted into the coaxial opening, wherein forces are then applied onto a circumferential surface of the drilled cylindrical blank for the production of the cylindrical housing. Another possibility for production is to roll a metal strip such that a concavity is formed, to create a bore therein and to apply forces in order to level out the concavity. An oval cross-section is imparted on each bore extending in concavities. The metal strip is wound about a mandrel to create the coaxial opening of the circular cross-section.Type: ApplicationFiled: September 28, 2007Publication date: January 28, 2010Inventor: Maximilian Kronberger

Patent number: 7275522Abstract: A valve has a piezoelectric actuator with a valve element, a valve body and a valve seat. In order to control the valve, the valve element is moved into the valve seat from a position remote from the valve seat by means of a charging process at a prescribable first time. A first value is determined being characteristic of the electrical power supplied to the piezoelectric actuator when the valve element meets the valve seat. A second value is determined being characteristic of the electrical power supplied to the piezoelectric actuator when the charging process of the piezoelectric actuator is concluded. An actual difference value between the second value and the first value is determined. A difference between a setpoint difference value and the actual difference value is supplied to a controller. An actuating signal for charging the piezoelectric actuator is determined as a function of the actuating variable.Type: GrantFiled: June 15, 2006Date of Patent: October 2, 2007Assignee: Siemens AGInventors: Jörg Beilharz, Maximilian Kronberger, Richard Pirkl, Christian Ribler, Harald Schmidt, Hans-Jörg Wiehoff
