Embodiment Construction

[0017] figure 1 Shown is a solenoid valve 1 , ie a de-energized closed outlet valve 2 . The solenoid valve 1 has a housing 3 which encloses a pole core 5 arranged in the region of the first end 4 along the longitudinal extension of the housing 3 and an armature 6 which adjoins the pole core in the axial direction, wherein in the helical Under the action of the compression spring 8, the armature 6 is kept in a de-energized state as a working chamber 7 spaced from the pole core 5 with approximately the width of the gap for the axial movement of the armature 6. One side of the helical compression spring is supported on the pole core 5 and The other side rests on the bottom 29 of the longitudinal bore 9 provided in the armature 6 . The armature 6 has at its end 10 opposite the longitudinal bore 9 for receiving the compression spring 8 a closing ball 11 which, in the de-energized state of the solenoid valve 1 shown, will be arranged in the housing 3. The valve opening 12 is close...

Abstract

The invention relates to a solenoid valve comprising a housing (3), a pole core (5) and a displaceably mounted armature (6) which is at least partially accommodated in the housing. According to the invention, the housing (3) is embodied as a single-part housing pot-shaped element (14) having a cover wall (22) and a base wall (15). The pole core (5) is compressed axially in the housing pot-shaped element (14) until it is in a desired axial position, and a first front side (19) of the pole core (5) is opposite the base wall (15) and a second front side (20) of the pole core (5), opposite the first front side (19), is opposite the armature (6). The invention also relates to a method for producing said type of solenoid valve.

Description

technical field [0001] The invention relates to a solenoid valve having a housing, a pole core and an armature at least partially accommodated in the housing and mounted displaceably. Furthermore, the invention relates to a method for producing such a solenoid valve. Background technique [0002] Solenoid valves of the type mentioned in the preamble are known. These solenoid valves are used, for example, as control and regulating valves for various media, in particular as hydraulic valves in brake circuits of motor vehicles. De-energized closed embodiments are known from the prior art, for example as so-called discharge valves with a pole core which is partially inserted into a sheath which is open at the end and which is connected to the sheath which is open at the end in the region of its end. welded together. [0003] A solenoid coil is placed on the pole core, which enables the operation of the solenoid valve by means of an electromagnetic field oriented by means of t...
