Patent number: 8528879Abstract: The invention relates to a method and a device for producing a high-pressure-tight connection between a pole core and a valve sleeve of a solenoid valve and to an associated valve cartridge for a solenoid valve. According to the invention, the pole core is placed in a two-part compression mold, which comprises a middle die and an outer die, in such a way that a joining gap is produced between an inner bore of the outer die and the placed-in pole core. Subsequently, the pole core is placed against the valve sleeve and the valve sleeve is inserted into the joining gap. Then, the middle die and the outer die are pressed simultaneously with the pole core such that the valve sleeve passes into the joining gap. When a pressed diameter of the pole core is reached, the valve sleeve expands and is shaped in the joining gap between a first shaping edge and a second shaping edge and is joined onto the pole core. The diameter of the inner bore tapers between the first shaping edge and the second shaping edge.Type: GrantFiled: July 3, 2008Date of Patent: September 10, 2013Assignee: Robert Bosch GmbHInventors: Friedrich Mueller, Guenther Schnalzger, Martin Kirschner

Publication number: 20100206252Abstract: The invention relates to a high-pressure pump for a fuel system of an internal combustion engine, having at least one inlet valve device with a valve element, a valve seat for the valve element, and an actuating tappet which can positively push the valve element in an opening direction. In order to create a high-pressure pump for a fuel system of an internal combustion engine which can be produced even more cost-effectively and which has a lower level of wear and therefore a longer service life, it is proposed that the valve element have a positioning mechanism which centers the valve element on the valve seat when the valve element comes into contact or is in contact with the valve seat.Type: ApplicationFiled: May 27, 2008Publication date: August 19, 2010Inventors: Bernd Schroeder, Markus Becker, Guenther Schnalzger, Martin Kirschner

Patent number: 7731304Abstract: The invention relates to an electronically regulatable vehicle brake system with traction control, in which a master cylinder is connected indirectly via a hydraulic unit to at least one wheel brake. The hydraulic unit has electromagnet valves and an externally triggerable pressure generator, for modulating the wheel brake pressure, optionally independently of the driver. For preventing wheel slip, the pressure generator is connected by its intake side to an intake conduit, among other things, that is controllable by an intake valve. To enhance the dynamics and improve the regulatability of a vehicle brake system, a self-aspirating pressure fluid storage unit is connected to the intake conduit and makes an aspiration volume available to the pressure generator.Type: GrantFiled: December 16, 2005Date of Patent: June 8, 2010Assignee: Robert Bosch GmbHInventors: Bernd Groll, Guenther Schnalzger

Publication number: 20100059698Abstract: The invention relates to a solenoid valve having a magnetic assembly and a valve cartridge. The valve cartridge includes a capsule, a valve insert connected to the capsule and an armature that is mobile in the capsule. The armature includes a tappet having a first closing element. A magnetic force produced by the magnetic assembly displaces the armature towards the valve insert. As a result, the first closing element sealingly plunges into a main valve seat.

Publication number: 20080224534Abstract: The invention relates to a solenoid valve arrangement for an automotive braking system which arrangement is configured as a three-position/three-way valve. The invention is improved over the prior art in that two armatures and a single armature winding are assembled together such that both armatures can be displaced by the single armature winding. Each of the two armatures is associated with a respective sealing seat and the two sealing seats are situated on one side of the solenoid valve device, viewed in the axial direction of the armatures. The two sealing seats are embodied in a particularly advantageous fashion in or on a common sealing washer. The two sealing seats are arranged in a single sealing washer in such a way that the latter can be preassembled and then inserted into a predetermined location in the final assembly of the vehicle brake system solenoid valve device.Type: ApplicationFiled: May 31, 2006Publication date: September 18, 2008Inventors: Guenther Schnalzger, Martin Kirschner

Patent number: 6976665Abstract: An electromagnetically actuatable valve for hydraulic control devices in motor vehicles is embodied as a pressure-equalized seat valve in a mode of construction comprising a hydraulic part with a valve dome and an electrical part that can be slipped onto the valve dome. In a magnet valve that is normally open, the tubular tappet that supports the closing member is supported at one point in a first bearing point, in terms of the longitudinal direction, that is embodied as a slide bearing, and a bearing ring that forms the sealing point accomplishes the hydraulic pressure equilibrium with the effective sealing diameter of the closing member that together with the valve seat forms the second bearing point. With the valve, very short switching times, in particular less than 0.5 ms, can be achieved with an economical mode of construction.Type: GrantFiled: May 12, 2004Date of Patent: December 20, 2005Assignee: Robert Bosch GmbHInventors: Stefan Seitz, Andreas Schrade, Guenther Schnalzger, Hubert Hueber, Martin Kirschner, Ralph Appelt
