Patent number: 10662913Abstract: The teachings of the present disclosure describe an injector having an injector housing, an actuator, and a nozzle needle, wherein the actuator is arranged in an actuator space of the injector housing. The injector may include a control piston bore in the injector housing, in which a control piston is arranged, a leakage pin bore between the actuator space and the control piston bore, and a leakage pin coupling the control piston to the actuator, the leakage pin arranged in the leakage pin bore. The control piston may be hydraulically connected to the nozzle needle in order to open or close an outlet opening of the injector housing. The injector may include a high pressure line configured to convey a fuel under pressure to the nozzle needle and a feedline in the injector housing connecting the leakage pin bore to the high pressure line.Type: GrantFiled: November 7, 2013Date of Patent: May 26, 2020Assignee: CONTINENTAL AUTOMOTIVE GMBHInventors: Roman Etlender, Willibald Schuerz, Werner Reim

Patent number: 10180123Abstract: A method is provided for pairing at least two injectors, e.g., two fuel injectors for a direct injection system of an internal combustion engine, wherein a criterion for the pairing of the at least two injectors is a total leakage and/or a pressure difference at a transfer pin of the respective injector. A method for producing an injector, e.g., a fuel injector for a direct injection system of an internal combustion engine, is also provided, wherein at least two instances of mechanical backlash, e.g., instances of pairing backlash, that are relevant to injection amounts, leakage amounts, and/or pressure differences of the injector are paired with each other.Type: GrantFiled: June 23, 2014Date of Patent: January 15, 2019Assignee: CONTINENTAL AUTOMOTIVE GMBHInventors: Willibald Schuerz, Roman Etlender, Werner Reim

Patent number: 10113523Abstract: An injector includes an actuator arranged in an actuator space, a piston guide having a bore hole, and a piston arranged in the bore hole. The piston has a first end face facing the actuator and delimiting a first space in and/or on the bore hole, and a second end face lying opposite the first space and delimiting an adjoining second space in and/or on the bore hole. The piston is arranged between the first and second spaces, and a gap extends around the circumference of the piston between the piston and the bore hole. The piston includes a first material and the piston guide includes a second material, the first and second materials having different thermal expansion properties such that when the piston guide and/or piston are heated, the gap width of the gap decreases to limit fuel leakage between the first space and second spaces.Type: GrantFiled: May 22, 2014Date of Patent: October 30, 2018Assignee: CONTINENTAL AUTOMOTIVE GMBHInventors: Roman Etlender, Werner Reim, Willibald Schuerz

Publication number: 20160252068Abstract: A piezo actuator for a fuel injector, including: a piezo layer stack having a longitudinal extension; and an insulation layer surrounding the piezo layer stack. The insulation layer has an insulation layer outer surface, facing away from the piezo layer stack, which defines an outer diameter of the insulation layer. In addition, a preloading device for preloading the piezo layer stack is also provided along the longitudinal extension, wherein the preloading device has a preloading device inner surface, facing towards the piezo layer stack, which defines an inner diameter of the preloading device. In a non-assembled state, the outer diameter of the insulation layer is greater that the inner diameter of the preloading device, such that, in an assembled state, the insulation layer is compressed in the preloading device. The invention also relates to a fuel injector having said piezo actuator.Type: ApplicationFiled: June 11, 2015Publication date: September 1, 2016Inventors: Willibald SCHĂRZ, Werner REIM

Patent number: 4553659Abstract: An insertion apparatus is provided for inserting continuously supplied products into containers. The insertion apparatus includes an ejection device which moves parallel to products along an endless conveyor system, and a curved directrix which is adapted to guide the ejection device in a direction which effects lateral movement of the products. The directrix is inclined relative to the direction of movement of the products, and a device is provided for bypassing movement of the ejection device with respect to the directrix so that the ejection device will move independently of the movement of the products.Type: GrantFiled: May 12, 1982Date of Patent: November 19, 1985Assignee: IWK Verpackungstechnik GmbHInventors: Werner Reim, Dieter Pluschow

Patent number: 4502262Abstract: Apparatus for positioning inserts relative to a product on a product chain prior to packaging the product in a product container, the apparatus includes insert transport belts for conveying the inserts to an insert pincer chain adapted to position the inserts relative to the product prior to release of the inserts from the insert pincer chain. The insert pincer chain is positioned below the product chain. The insert pincer chain is directed along the side of the product chain in a transfer zone at which the inserts are transferred from the insert pincer chain to the product chain.Type: GrantFiled: May 5, 1982Date of Patent: March 5, 1985Assignee: IWK Verpackungstechnik GmbHInventors: Werner Reim, Horst Garthe

Patent number: 4289228Abstract: A device for the intermittent conveyance of receptacles for receiving packing or filling material in an intermittently operating machine, particularly a tube filling and closing machine, comprising, first and second parallel spaced apart linear guideways facing at angles to each other and a plurality of sets, each adapted for receiving one of the receptacles, slidably mounted on the first and second guideways. A driving unit is provided for moving the cassettes linearly along the guideways and for tilting and displacing the cassettes from one guideway to the other when each cassette reaches the end of the one guideway. The cassettes thus execute a cyclic movement along the first and second guideways.Type: GrantFiled: December 6, 1979Date of Patent: September 15, 1981Assignee: Industrie-Werke Karlsruhe Augsburg AktiengesellschaftInventors: Werner Reim, Hermann Gernlein, Helmuth Zimmermann
