20120256109 | Magnetic Valve and Driver Assistance Device having such a Magnetic Valve - A magnetic valve includes a main body and a closure element, which is connected to an end region of the main body and which can be impinged by a fluid pressure. The main body has at least one first support surface allocated to the closure element in the end region thereof. A support element is provided, which is connected to the main body and has at least one other second support surface serving as a bearing surface or forms the bearing surface together with the first support surface. The bearing surface is larger than the first support surface. | 10-11-2012 |
20120273707 | Solenoid Valve for Controlling a Fluid - A solenoid valve for controlling a fluid comprising an armature, a valve member which has a dome-shaped end region and which is connected to the a mature and is movable jointly with the armature, a first guidance region being provided on the armature, and a valve body with a valve seat, with a through orifice, the valve member opening and closing the through orifice on the valve seat, and with a guide element which defines a second guidance region for guiding the valve member and which guides the valve member when the solenoid valve is open, the guide element being formed in one piece with the valve body. | 11-01-2012 |
20130009081 | Solenoid Valve and Driver Assistance Device Comprising said type of Solenoid Valve - A solenoid valve includes an armature which is arranged in the region of at least one magnetic coil. At least one radial recess extending essentially in the radial direction, traversing at least in parts the front surface of the armature is provided. A driver assistance device including said type of solenoid valve is also disclosed. | 01-10-2013 |
20130193362 | Valve Module, in particular Solenoid Valve for a Brake System of a Motor Vehicle, Method for the Production of said Type of Valve Module - A valve module, in particular a solenoid valve for a brake system of a motor vehicle, is disclosed. The valve module includes an essentially cylindrical-shaped valve base body in which a valve needle is arranged in an axially displacable manner, and a housing cap which closes the valve base body on one end. The cap is maintained on the valve base body by at least one holding device. The maintaining device includes at least one recess on the outer surface of the cover of the valve base body into which plastically deformed material of the housing cap is introduced. A method for producing this type of valve module is also disclosed. | 08-01-2013 |
20140027658 | MAGNET VALVE FOR CONTROLLING A FLUID - 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. | 01-30-2014 |
20160059820 | VALVE FOR A COLD GAS GENERATOR AND AIRBAG SYSTEM - A valve for a cold gas generator for an airbag in a vehicle includes: a valve chamber; a control chamber; a control piston; an overflow channel; a retaining element; and a shutoff element. The valve chamber includes an inlet from the cold gas generator and an outlet to the airbag. The control piston separates the control chamber and the valve chamber. The control piston is movable between an open position and a closed position, the control piston releasing the outlet in the open position and closing it in the closed position. The control piston has (i) a first active piston surface on the side of the valve chamber, and (ii) a second active piston surface on the side of the control chamber. The first piston surface is smaller than the second piston surface. The overflow channel fluidically connects the valve chamber and the control chamber to one another. | 03-03-2016 |
