Problems solved by technology

In this way, the speed at which the solenoid valve can move is reduced
But this reduces the maximum adjustment speed that the solenoid valve can achieve, that is, increases the minimum adjustment time that the solenoid valve can achieve.

Embodiment Construction

[0024] The figure shows a solenoid valve 1 , which is, for example, a component of a driver assistance device not shown here. The solenoid valve 1 has an armature 2 operatively connected to a sealing element 3 of the solenoid valve 1 . The sealing element 3 cooperates with a valve seat 5 formed in the valve body 4 to open or shut off the flow connection between the inlet connection 6 and the outlet connection 7 of the solenoid valve 1 . In the exemplary embodiment shown here, a filter 8 is assigned to the outlet connection 7 . Of course, a filter (not shown here) can additionally or alternatively be assigned to the inflow connection 6 . Depending on the arrangement of the inflow port 6 and the outflow port 7 , the solenoid valve 1 shown here is designed for axial inflow and radial outflow (relative to the longitudinal axis 9 of the solenoid valve 1 ). Of course, however, the inflow and outflow directions can also be arranged arbitrarily.

Abstract

The invention relates to a magnet valve (1) comprising a magnet armature (2) that is operatively connected to a sealing element (3) of the magnet valve (1) in order to displace said element and comprising at least one flow path (18) via which fluid chambers (16, 17) that lie on opposing faces of the magnet armature (2) can be connected or are connected in a fluidic manner. At least one damping element (19) is arranged in the magnet valve (1) in a displaceable manner in the axial direction, said damping element protruding into the flow path (18) at least in some regions.

Description

technical field [0001] The invention relates to a solenoid valve having an armature and at least one flow path, the armature being operatively connected to a sealing element of the solenoid valve for displacing the sealing element, through which at least one flow path is arranged on the armature The fluid cavities on opposite sides of the two are fluidly connected or fluidly connectable. The invention also relates to a driver assistance device. Background technique [0002] A solenoid valve of the type mentioned at the outset is known from the prior art. Said solenoid valves are often used in driver assistance devices, in particular ABS, TCS or ESP devices. The solenoid valve has an armature which is displaceable in the solenoid valve, in particular axially. The armature is operatively connected to the sealing element of the solenoid valve, so that when the armature is displaced, the sealing element is also displaced. The sealing element is usually provided for closing o...
