Embodiment Construction

[0025] figure 1 A cross section through a region of a solenoid valve 1 is shown, which is arranged in an external device 2 mentioned only slightly in the figure. Solenoid valve 1 has a valve body 3 and a housing 4 , wherein an armature 5 is mounted axially movable in housing 4 . Formed in the valve body 3 is an ascending channel 6 which is fluidically connected to at least one inlet channel 7 . Fluid can be supplied to the solenoid valve 1 via the inlet channel 7 . In this case, the ascending channel 6 is configured radially (relative to the longitudinal axis 8 of the solenoid valve 1 ). In contrast, the inlet channel 7 opens radially from there into the outer peripheral surface 9 of the valve body 3 or the outer peripheral surface 9 of the solenoid valve 1 .

[0026] To form the ascending channel 6 , starting from the end face 10 of the solenoid valve 1 or the end face 10 of the valve body 3 , a hole is first drilled axially into the valve body 3 . The bore is then closed...

Abstract

The invention relates to a magnetic valve (1) having a valve body (3), wherein the valve body (3) comprises a valve seat (12), which can be sealed by a sealing element (14), at least one outlet channel (13), which opens into a fluid chamber (15) of the magnetic valve (1) accommodating at least sections of the sealing element (14), and a flow directing element (16) surrounding at least sections of the sealing element (14), wherein the sealing element (14) is operationally connected to a magnetic anchor (5) arranged in a magnetic anchor chamber (17) designed on a side of the flow directing element (16) facing away from the fluid chamber (15). According to the invention, the flow directing element (16) encompasses at least sections of the valve body (3) and a connection channel (21) establishing a fluid connection between the fluid chamber (15) and the magnetic anchor chamber (17) is in fluid connection to a radial recess (29) extending through a wall (30) of the valve body (3) in the radial direction. The invention further relates to a driver assistance device having such a magnetic valve (1).

Description

technical field [0001] The invention relates to a solenoid valve having a valve body in which there is a valve seat which can be closed with a sealing element, at least one outlet channel leading to a fluid chamber of the solenoid valve which at least partially accommodates the sealing element, and a A flow guide element which at least partially surrounds a sealing element which is operatively connected to an armature arranged in an armature chamber which is formed on the side of the flow guide element facing away from the fluid chamber. The invention also relates to a driver assistance device. Background technique [0002] Solenoid valves of the type described above are known from the prior art. Such solenoid valves, for example 2 / 2-way solenoid valves without flow closing or 2 / 2-way solenoid valves without flow closing, can be used in ABS systems, TCS systems or ESP systems. These solenoid valves each have a valve seat that can be closed off with a sealing element. For ...
