Patent number: 9194347Abstract: An injector having a valve opening, a cylindrical pipe, a valve opening, a valve needle situated inside the pipe in the radial direction and guided to allow axial displacement; a solenoid coil situated outside the pipe in the radial direction; a solenoid core disposed inside the pipe in the radial direction; and a magnetic armature situated inside the pipe, opposite the solenoid core in the radial direction, the magnetic armature being disposed on the valve needle. The pipe is a magnetic first material in a first pipe region and a third pipe region, the first region facing the valve opening in the axial direction, and the third pipe region facing away from the valve opening in the axial direction. The pipe is a non-magnetic second material in a second pipe region, the second pipe region being between the first pipe region and the third pipe region in the axial direction.Type: GrantFiled: December 1, 2010Date of Patent: November 24, 2015Assignee: ROBERY BOSCH GMBHInventors: Juergen Graner, Martin Maier, Juergen Lander, Jochen Rager

Patent number: 9188094Abstract: A fuel injector for fuel-injection systems of internal combustion engines includes an electromagnetic actuating element having a solenoid coil, a fixed core, an outer magnetic circuit component, and a movable armature for actuating a valve-closure element, which cooperates with a valve-seat surface provided on a valve-seat element. The injector is characterized by its extremely small outer dimensions. The flexibility in the installation of fuel injectors of varying valve lengths, which is made possible very simply due to the special modular design, is significantly increased in this manner. An optimized dimensioning of the electromagnetic circuit allows for a DFR (dynamic flow range) greater than 17, the DFR being defined as the quotient of qmax/qmin.Type: GrantFiled: July 26, 2011Date of Patent: November 17, 2015Assignee: ROBERT BOSCH GMBHInventors: Juergen Graner, Martin Maier, Takuya Mizobe, Bernd Rieg, Volker Sohm, Juergen Lander

Patent number: 9068542Abstract: A fuel injector for fuel injection systems of internal combustion engines. The valve includes an electromagnetic actuating element which has a solenoid, a solid core, an external magnetic circuit component, and a movable armature for activating a valve closing member which cooperates with a valve seat surface provided on a valve seat member. The valve has extremely small outer dimensions. By optimizing the dimensions of the electromagnetic circuit, the outer diameter of the external magnetic circuit component in the peripheral area of the solenoid is 10.5 mm<DM<13.5 mm. This increases the flexibility in installing fuel injectors having different valve lengths, which are made possible due to the special modular design. The valve is suitable as a fuel injector in particular for use in fuel injection systems of mixture-compressing, spark ignition internal combustion engines.Type: GrantFiled: July 26, 2011Date of Patent: June 30, 2015Assignee: ROBERT BOSCH GMBHInventors: Juergen Graner, Martin Maier, Bernd Rieg, Volker Sohm, Juergen Lander, Takuya Mizobe

Publication number: 20140027545Abstract: A fuel injection valve for fuel injection systems of internal combustion engines. The valve includes an electromagnetic actuating element having a solenoid, a solid core, an outer magnetic circuit component, and a movable armature for actuating a valve closing element that works together with a valve seat surface provided on a valve seat element. The valve has extremely small outer dimensions. Due to an optimized dimensioning of the electromagnetic circuit, the outer diameter of the outer magnetic circuit component in the circumferential area of the solenoid DM<=11 mm. This increases flexibility in the installation of fuel injection valves having various valve lengths, which are very easily enabled due to the particular modular construction. The valve is suitable as a fuel injection valve, particularly for use in fuel injection systems of mixture-compressing externally ignited internal combustion engines.Type: ApplicationFiled: July 26, 2011Publication date: January 30, 2014Inventors: Juergen Graner, Martin Maier, Bernd Rieg, Volker Sohm, Juergen Lander, Takuya Mizobe

Patent number: 8430078Abstract: A fuel injection valve is characterized in that a multi-fan stream nozzle is shaped, downstream from a fixed valve seat that is provided on the inner wall of a valve sleeve, directly into the valve sleeve itself. The multi-fan stream nozzle is integrated directly in the region of a bulge formed at the downstream end of the valve sleeve. The multi-fan stream nozzle, serving as an atomization device, possesses a plurality of slit-shaped spray openings, so that from the sheets of liquid emerging from the spray openings, sheet packets are formed in which individual sheets of liquid extend divergently from one another. Introduction of the spray openings into the deep-drawn valve sleeve is effected using ultrashort-pulse laser technology. The fuel injection valve is suitable in particular for use in fuel injection systems of mixture-compressing spark-ignited internal combustion engines.Type: GrantFiled: December 17, 2008Date of Patent: April 30, 2013Assignee: Robert Bosch GmbHInventors: Joerg Heyse, Wilhelm Hopf, Juergen Lander, Dieter Holz

Patent number: 5810330Abstract: A magnetic valve that switches at high differential pressures and furnishes a large flow cross section. The magnetic valve has an armature, which when current is supplied to a coil is movable toward a pole core counter to the force of a restoring spring. The armature is capable of opening an auxiliary valve of small sealing diameter directly and a main valve of large sealing diameter indirectly. The auxiliary valve and the main valve have a common closing body, which is movable relative to the armature with a limited stroke. The auxiliary valve communicates through a bore of the closing body with the outflow side of the magnetic valve. In the open position of the magnetic valve, the closing body is held in a position that blocks the auxiliary valve by the action of the second restoring spring. The magnetic valve is suitable in particular for slip-controlled hydraulic brake systems of motor vehicles.Type: GrantFiled: August 22, 1996Date of Patent: September 22, 1998Assignee: Robert Bosch GmbHInventors: Hubert Eith, Helmut Staib, Michael Friedow, Martin Scheffel, Juergen Lander, Gerhard Stokmaier

Patent number: 5788344Abstract: The invention relates to a hydraulic unit for a vehicle brake system with ABS. Before being filled with brake fluid, the brake system must be evacuated in order to achieve complete bleeding. In order to evacuate a return line, which is separated from a brake line by pressure reduction magnet valves that are closed in their position of repose, it is known to provide a connecting line with a check valve between the brake line and the return line. The hydraulic unit connects the check valves in parallel to the magnet valves and integrates the check valves with the magnet valves. This simplifies assembly. Since no additional holes and conduits in the hydraulic unit are necessary, existing hydraulic units can be used.Type: GrantFiled: August 20, 1996Date of Patent: August 4, 1998Assignee: Robert Bosch GmbHInventors: Michael Friedow, Juergen Lander, Heidi Kroebel

Patent number: 5762318Abstract: A pressure adjuster that has at least one valve, united with a valve block, with a valve dome that protrudes from the valve block. A cap includes a coil which is slipped over the valve dome. Electrical contact elements extend from both the coil and the cap and are joined together in a material bond. The electrical contact elements of the coil and of the cap are embodied resiliently. The electrical contact elements effect both the electrical connection and the mounting function for the coil. Moreover, the electrical contact elements allow aligning the coil as it is slipped onto the valve dome. The electrohydraulic pressure adjuster can be used in slip-controlled vehicle brake systems.Type: GrantFiled: October 15, 1996Date of Patent: June 9, 1998Assignee: Robert Bosch GmbHInventors: Helmut Staib, Guenther Glock, Michael Friedow, Juergen Lander, Ulrich Pechtold
