Embodiment Construction

[0025] figure 1 A cross section of a region of the solenoid valve 1 is shown, which is arranged in an external device 2 which is only shown schematically here. The solenoid valve 1 has a valve body 3 and a housing 4, in which an armature 5 is movably supported in the axial direction. An ascending passage 6 is constructed in the valve body 3 and is in flow communication with at least one inflow passage 7. The solenoid valve 1 can be supplied with fluid through the inflow channel 7. The ascending channel 6 is here formed along the axial direction (relative to the longitudinal axis 8 of the solenoid valve 1 ). On the contrary, the inflow passage 7 flows from the ascending passage 6 into the peripheral surface 9 of the valve body 3 or the solenoid valve 1 in the radial direction.

[0026] In order to construct the ascending passage 6, starting from the end surface 10 of the solenoid valve 1 or the valve body 3, a hole is first drilled in the valve body 3 in the axial direction. Su...

Abstract

The invention relates to a magnetic valve (1) comprising a valve body (3) provided with a valve seat (12) which can be closed by a sealing element (14), at least one outlet channel (13) which leads into a fluid chamber (15) of the magnetic valve (1), receiving the sealing element (14) at least in parts, and a flow guiding element (16) which surrounds the sealing element (14) at least in parts. Said sealing element (14) is operatively connected to a magnet armature (5) arranged in a magnet armature chamber (17) embodied on one side of the flow guiding element (16) facing away from the fluid chamber (15). According to the invention, the valve body (3) and the flow guiding element (16) together form at least one connection channel (21) producing a fluidic connection between the fluid chamber (15) and the magnet armature chamber (17). The invention also relates to a driver assistance device comprising said type of magnetic valve.

Description

Technical field [0001] The invention relates to a solenoid valve with a valve body, in which a valve seat that can be closed by a sealing element, at least one discharge channel leading into a fluid cavity of a solenoid valve at least partially containing the sealing element, and at least partly surrounding The flow guiding element of the sealing element, wherein the sealing element is effectively connected with the armature arranged in the armature cavity, and the armature cavity is configured on the side of the guiding element away from the fluid cavity. The invention also relates to a driver assistance device. Background technique [0002] Solenoid valves of the type mentioned at the beginning are known from the prior art. Such solenoid valves, such as the two-position two-way solenoid valve with no flow closing and the two-position two-way solenoid valve with no flow closing, can be used in ABS, TCS or ESP systems. The solenoid valve has a valve seat, which can be closed wi...
