Patent number: 9938947Abstract: A decoupling element is described for a fuel injection device which is characterized in particular by a low-noise design. The fuel injection device includes at least one fuel injector, a receiving bore in a cylinder head for the fuel injector, and the decoupling element between a valve housing of the fuel injector and a wall of the receiving bore. The decoupling element is designed as a decoupling system having a spring ring and a conical washer. The fuel injection device is suitable for injecting fuel into a combustion chamber of a mixture-compressing spark-ignition internal combustion engine in particular.Type: GrantFiled: November 9, 2012Date of Patent: April 10, 2018Assignee: ROBERT BOSCH GMBHInventors: Jens Pohlmann, Michael Fischer, Andreas Glaser, Markus Friedrich, Martin Scheffel, Stefan Woerz, Martin Buehner, Thomas Gerschwitz, Anh-Tuan Hoang

Patent number: 7637443Abstract: A fuel injector, e.g., for fuel-injection systems of internal combustion engines in motor vehicles, includes a valve housing including a sleeve-shaped housing section; and a solenoid, situated on the housing section, having a coil brace, magnetic coil and magnetic cup. To protect the magnetic coil from salt fog that arises under specific environmental conditions and penetrates along the contact areas of solenoid and housing section, the coil brace with wound magnetic coil is completely enclosed on all sides by a one-piece plastic coat.Type: GrantFiled: October 5, 2005Date of Patent: December 29, 2009Assignee: Robert Bosch GmbHInventors: Martin Scheffel, Andreas Glaser, Jens Pohlmann, Thomas Gerschwitz, Christina Gerescher

Patent number: 7500648Abstract: A fuel injector has a piezoelectric or magnetostrictive actuator, which actuates a valve-closure member cooperating with a valve-seat surface a sealing seat. An hydraulic coupler includes a master piston, a slave piston, and a coupler volume formed in-between, the coupler volume being connected to a compensating chamber via a throttle. An elastic flexible section delimits the compensating chamber at least partially, and the coupler volume, the throttle, and the compensating chamber are filled with an hydraulic medium. The flexible section exerts a pressure on the hydraulic medium due to prestressing, and the force of a compression spring, which is braced either directly and/or via fixed components on the slave piston and the master piston, is directed with an initial stress in such a way that the force enlarges the coupler volume.Type: GrantFiled: February 14, 2004Date of Patent: March 10, 2009Assignee: Robert Bosch GmbHInventors: Werner Kammerer, Klaus Noller, Hubert Stier, Dietmar Schmieder, Michael Huebel, Thomas Gerschwitz, Christian Leitner

Patent number: 7422006Abstract: A fuel injector has a piezoelectric or magnetostrictive actuator, which actuates a valve-closure member cooperating with a valve-seat surface to form a sealing seat. A hydraulic coupler includes a master piston, a slave piston, and a coupler volumeformed in-between. The master piston and the slave piston are axially displaceable with respect to one another. The coupler volume is connected to a compensating chamber via a throttle. A flexible section delimits the compensating chamber at least partially, and the coupler volume, the throttle, and the compensating chamber are filled with a hydraulic medium. At least one spring element directly or indirectly exerts pressure on the flexible section from the outside, via fixed components.Type: GrantFiled: October 29, 2004Date of Patent: September 9, 2008Assignee: Robert Bosch GmbHInventors: Klaus Noller, Peter Land, Christof Vogel, Michael Huebel, Thomas Gerschwitz

Publication number: 20060043213Abstract: A fuel injector has a piezoelectric, electrostrictive or magnetostrictive actuator, a valve needle, which is in operative connection with the actuator and acted upon with a restoring force by a valve spring in a closing direction to actuate a valve-closure member; and an hydraulic coupler which encompasses a piston that at least partially engages in a receiving opening and forms a coupler gap therewith, which is filled with an hydraulic fluid; a cavity being formed in the piston, which is open toward the coupler gap and at least partially filled with the hydraulic fluid and forms a compensating chamber.Type: ApplicationFiled: January 26, 2004Publication date: March 2, 2006Inventors: Thomas Gerschwitz, Klaus Noller, Fevzi Yildirim
