Patent number: 9382888Abstract: An injection nozzle for injecting media into a combustion chamber includes a nozzle body having a tip with spray holes and protruding into the combustion chamber, and a heat protection sleeve that surrounds and is positioned on a combustion chamber side of an end area of the nozzle body. The injection nozzle is inserted into an accommodating hole of a retaining part, whereby the end area of the nozzle body interacts with the accommodating hole, and whereby the sleeve is positioned there-between. The sleeve further has a first and second area which are located at an axial distance from each other and which have respective sealing surfaces that interact in a sealing manner with either (i) an annular seat surface extending in a radial plane, or (ii) a cone-shaped seat surface of the accommodating hole or of the nozzle body.Type: GrantFiled: March 28, 2013Date of Patent: July 5, 2016Assignee: Robert Bosch GmbHInventor: Heinrich Werger

Publication number: 20150083829Abstract: A method for producing injection holes in fuel injection nozzles for internal combustion engines. An injection hole is formed by at least one abrading manufacturing method. An injection nozzle is subsequently subjected to a hardening treatment at least in the region of the injection hole, such that the injection hole surface is hardened over the entire axial length thereof.Type: ApplicationFiled: August 28, 2012Publication date: March 26, 2015Applicant: Robert Bosch GmbHInventor: Heinrich Werger

Patent number: 8178213Abstract: In a method for applying a multilayer wear-resistant coating on metallic, optionally already coated, surfaces, the coating is composed of at least two anti-wear layers (5) and an intermediate layer (10) each arranged between two anti-wear layers (5). The intermediate layer (10) is comprised of a material composition containing the material of the anti-wear layer (5) and a further material, wherein the application of the intermediate layer (10) is effected with a content of the material of the anti-wear layer (5) decreasing over a first transition region (a) and a content of the material of the anti-wear layer (5) increasing over a second transition region (b), the content of the material of the anti-wear layer (5) in the intermediate layer (10) being selected to be at least 5% by weight in every point.Type: GrantFiled: June 4, 2007Date of Patent: May 15, 2012Assignee: Robert Bosch GmbHInventor: Heinrich Werger

Publication number: 20090114744Abstract: In a device for the injection of fuel into the combustion chamber of an internal combustion engine, including an injector nozzle and a nozzle needle guided in a longitudinally displaceable manner within the injector nozzle for selectively releasing and blocking the fuel flow to the injection openings, the nozzle needle is at least partially surrounded by a nozzle prechamber, wherein a control element determining a supply cross-section for the fuel flow to the injection openings is arranged in the nozzle prechamber.Type: ApplicationFiled: August 23, 2006Publication date: May 7, 2009Inventors: Martin Bernhaupt, Heinrich Werger

Patent number: 6712296Abstract: A fuel injection valve for internal combustion engines, having a pistonlike valve member, axially movable counter to the closing force of a spring, in the bore of a valve body and that controls at least one injection opening. A control chamber surrounding the valve member is disposed between a guided portion of the valve member and an oil leakage chamber that receives the spring; the valve member communicates with an inlet conduit via a throttling annular gap and with the oil leakage chamber via a control bore. In the closing motion of the valve member away from the valve seat, fuel is positively displaced out of the control chamber into the oil leakage chamber by a pressure face. In a portion of the valve member stroke, the control chamber is closed, except for a throttle gap formed between a cylindrical portion and the control bore, toward the oil leakage chamber, and the fuel pressure in the control chamber rises, since the outflow can now take place only via the throttle gap.Type: GrantFiled: December 26, 2001Date of Patent: March 30, 2004Assignee: Robert Bosch GmbHInventors: Jaroslaw Hlousek, Heinrich Werger, Otto Hagenauer
