Publication number: 20180340625Abstract: An adjustable magnetic valve includes a magnet assembly and a guide sleeve in which a static component is arranged fixedly and a valve armature is arranged so as to be axially displaceable therein. The magnet assembly is pushed onto the static component and the guide sleeve. The static component forms an axial stop for the valve armature, which either forces a closing element into a valve seat or lifts the closing element from the valve seat depending on the direction in which the valve armature is driven. The valve armature and the static component are each formed as plastic components. The valve armature has a magnet receptacle that receives a permanent magnet, which is polarized in terms of its movement direction such that the permanent magnet is arranged within the magnet assembly regardless of the armature stroke.Type: ApplicationFiled: May 24, 2018Publication date: November 29, 2018Inventors: Edgar Kurz, Massimiliano Ambrosi, Michael Eisenlauer, Wolf Stahr, Wolfgang Schuller

Publication number: 20180209559Abstract: A normally closed solenoid valve includes a valve sleeve, a pole core fixedly positioned in the sleeve, an axially displaceable armature, a spring, a closing element, a valve seat, and an elastic component. The spring acts between the pole core and the armature in order to push the closing element into the valve seat. The closing element interacts with the armature. A prestressing force of the spring causes a deformation of the elastic component, which is positioned between the armature and the pole core, such that an impact of the armature on the pole core is damped via a regression of the deformation of the elastic component.Type: ApplicationFiled: May 30, 2016Publication date: July 26, 2018Inventors: Pascal Godbillon, Massimiliano Ambrosi, Michael Eisenlauer, Edgar Kurz, Norbert Alaze

Publication number: 20170307101Abstract: A valve armature assembly of a solenoid valve includes a body, a closing element, and an elastic damping element. The body includes a depression located at an end of the body. The closing element is received in the depression and includes a closing member configured to interact with a valve seat of the valve. The elastic element is positioned in the depression between the closing element and the body and is configured to damp a pulse resulting from the closing member striking the valve seat.Type: ApplicationFiled: August 3, 2015Publication date: October 26, 2017Inventors: Massimiliano Ambrosi, Edgar Kurz, Norbert Alaze, Michael Eisenlauer

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
