Patent number: 11390259Abstract: A solenoid valve, for controlling a brake pressure of a wheel brake of a slip-regulatable hydraulic brake system for a motor vehicle, includes a valve element, valve insert, valve seat, spring device, electromagnetic actuator, and armature. The valve element is longitudinally movably positioned at least partially in the valve insert, positioned between the armature and the valve seat, and configured to interact with the valve seat. The spring device, in an assembled position, has a force component acting on the valve element in an opening direction with respect to the valve seat. The electromagnetic actuator is configured to act on the valve element in a closing direction with respect to the valve seat. The valve element has a contact surface operatively connecting the valve element and armature, and configured such that a central axis of the valve element and the contact surface form a non-rectangular intersection angle.Type: GrantFiled: September 20, 2017Date of Patent: July 19, 2022Assignee: Robert Bosch GmbHInventors: Marcus Ertle, Stephan Steingass, Carsten Bodmann, Hans-Peter Bartosch, Stephan Knackert, Philipp Mueller

Patent number: 10969032Abstract: A solenoid valve for controlling the braking pressure of a wheel brake of a slip-controllable hydraulic brake system of a motor vehicle includes an armature, a valve insert, a valve seat, a valve element, and a spring device. The valve element is arranged in the valve insert in a longitudinally displaceable manner and acts together with the valve seat. The spring applies a force acting in the direction of opening with respect to the valve seat to the valve element in the installed position. The valve element can be actuated by an electromagnetic actuator in the closing direction with respect to the valve seat. The valve element is arranged between an anchor and the valve seat and is operatively connected to the anchor. A front face of the valve element facing the anchor has at least one projection and the projection defines a point of contact with the anchor.Type: GrantFiled: September 20, 2017Date of Patent: April 6, 2021Assignee: Robert Bosch GmbHInventors: Marcus Ertle, Klaus Landesfeind, Jens Norberg, Stephan Steingass, Thomas Weitze, Carsten Bodmann, Edwin Staib

Patent number: 9133957Abstract: A magnet valve configured to control a fluid includes an armature with a base region, a casing region, and a head region. The magnet valve also includes a valve element that is connected to the armature and an armature housing component. A flow path is formed between the armature and the armature housing component. The flow path runs from a lower armature chamber to an upper armature chamber and back to the lower armature chamber. The head region of the armature has a flattened section, and the upper armature chamber is defined between the armature housing component and the flattened section. At least one groove is formed on the casing region of the armature starting from the base region. The at least one groove ends in the casing region before the flattened section of the head region.Type: GrantFiled: December 15, 2011Date of Patent: September 15, 2015Assignee: Robert Bosch GmbHInventors: Massimiliano Ambrosi, Elmar Vier, Andreas Karl, Andreas Lechler, Stephan Steingass, Nicolas Houis, Jens Norberg, Gerhard Stokmaier

Patent number: 8596609Abstract: The invention relates to a solenoid valve with a magnet assembly and a valve cartridge having a pole core, a valve insert connected to the pole core, an armature which is guided within the valve insert in an axially movable manner between a closed position and an open position and is coupled to a closing element, and a valve body which is connected to the valve insert and has a main valve seat which is arranged between at least one first flow opening and a second flow opening. The axially movable armature, when the magnet assembly is energized, is moved by a generated magnetic force within the valve insert in the direction of the pole core counter to a spring force of a resetting spring and counter to a fluid force in order to lift the closing element out of the main valve seat; and to permit a flow of fluid between the at least one first flow opening and the second flow opening.Type: GrantFiled: July 2, 2008Date of Patent: December 3, 2013Assignee: Robert Bosch GmbHInventors: Klaus Heyer, Massimiliano Ambrosi, Michael Eisenlauer, Michael Rietsche, Michael Tischer, Stephan Steingass, Michael Hilden
