Embodiment Construction

[0029] figure 1 A cross-sectional view of the solenoid valve 1 is shown. The solenoid valve 1 has an armature 2 which is held in a housing 3 of the solenoid valve 1 and is displaceable in the axial direction (longitudinal axis 4 of the solenoid valve 1 ). The armature 2 serves to move the sealing element 5 , which is fixedly connected to the armature 2 for this purpose, for example by being screwed into the armature 2 or pressed into this armature. The sealing element 5 cooperates with a valve seat 6 formed in a valve body 7 . In this case, the valve body 7 is at least partially surrounded by the housing 3 and is therefore fixed relative thereto. In the valve body 7 , an ascending channel 8 , at least one inflow channel 9 and at least one discharge channel 10 are formed in addition to the valve seat 6 . The inflow channel 9 extends radially and opens into the ascending channel 8 . On the side facing away from the ascending channel 8 , the inflow channel 9 has an inflow con...

Abstract

The disclosure relates to a solenoid valve (1) and a driver assistance device, where the solenoid valve has a solenoid armature (2) which is operatively connected to a sealing element (5) of the solenoid valve (1) in order to move the same, and an armature opposing piece (16) which engages, at least in certain areas, in a receptacle opening (23) in the solenoid armature (2). There is provision here for the armature opposing piece (16) to be composed of a pole core (19) and an intermediate component (20) which is supported on the pole core (19), wherein only the intermediate component (20) is arranged at least in certain areas in the receptacle opening (23), and at least one venting opening (33, 36), which produces a fluid connection between the receptacle opening (23) and the surroundings of the solenoid armature, is formed in the intermediate component (20). The disclosure also relates to a driver assistance device.

Description

technical field [0001] The invention relates to a solenoid valve and a driver assistance device. The solenoid valve has an armature, which is operatively connected to a sealing element of the solenoid valve for changing its position, and an armature counter, which engages at least partially in a receiving opening of the armature. Background technique [0002] Solenoid valves of the type mentioned at the outset are known from the prior art. These solenoid valves are used, for example, in driver assistance systems, that is to say in particular in connection with ABS systems (Antilock Braking System), TCS systems (Traction Control System) or ESP systems (Electronic Stability Program System). The solenoid valve is designed, for example, as a 2 / 2 valve (2 / 2-way valve), which can be open or also closed when de-energized. In such solenoid valves a sealing element is usually arranged such that it can be displaced in its axial direction in order to co-operate sealingly with the val...
