Embodiment Construction

[0021] figure 1 The solenoid armature 1 of a solenoid valve not shown here is shown in an embodiment not according to the invention. The solenoid armature 1 is designed in the form of a closure cap, that is to say essentially hollow cylindrical, wherein the solenoid armature 1 is closed on one side and forms the end face 2 of the solenoid armature 1 . In the radial direction, the magnetic armature 1 is delimited by its outer peripheral surface 3 . Electromagnetic armature 1 has a substantially circular cross section in longitudinal section. In contrast to this substantially circular cross section, the outer peripheral surface 3 has axial recesses 4 and 5 diametrically opposite each other. The axial recesses 4 and 5 have their maximum length in the axial direction and engage radially in the end face 2 . as in figure 1 As can be seen in the figure, the axial recesses 4 and 5 each open into the end face 2 . The axial recesses 4 and 5 serve, for example, for feeding and / or al...

Abstract

The invention relates to a solenoid valve comprising an armature (1) which is arranged in the region of at least one magnetic coil. At least one radial recess (6, 10) extending essentially in the radial direction, traversing at least in parts the front surface (2) of the armature (1) is provided. The invention also relates to a driver assistance device comprising said type of solenoid valve.

Description

technical field [0001] The invention relates to a solenoid valve having a solenoid armature arranged in the region of at least one solenoid coil. Furthermore, the invention relates to a driver assistance device. Background technique [0002] Solenoid valves of the type mentioned at the outset are known from the prior art. Such solenoid valves are used, for example, in driver assistance devices such as ABS devices, TCS devices or ESP devices. The solenoid valve includes a solenoid armature arranged in the region of at least one solenoid coil for opening and closing the solenoid valve. For this purpose, the electromagnetic armature is preferably axially displaceable by means of the electromagnetic coil. This means that the magnetic armature can be moved at least into the closed position and the open position. When in the closed position, the solenoid valve is non-flowable, that is, fluid cannot flow from the inlet to the outlet of the solenoid valve. Contrary to the above...
