Problems solved by technology

However, deformation and / or damage to the valve element occurs in certain load states or operating states, in particular in the intermediate stroke position up to the large stroke position, wherein it can occur that the valve element can come into contact with the valve in the partial stroke position. physical contact
This could lead to impermissible damage or changes to the valve function

Embodiment Construction

[0019] Refer to the following Figure 1 to Figure 5 A solenoid valve for controlling fluid according to a preferred embodiment of the present invention is described in detail.

[0020] figure 1 A schematic cross-sectional view of a solenoid valve 1 for controlling fluids according to a preferred embodiment of the present invention is shown.

[0021] The solenoid valve 1 comprises an armature 2 , a valve element 3 and a valve body 4 which are arranged coaxially with the axis X-X in the pole housing 9 or in a housing 13 connected thereto. The armature 2 is installed here both in the pole housing 9 and in the housing 13 . The valve element 3 is connected to the armature 2 and is movable together with said armature. A first guide region 20 for guiding the armature 2 is provided on the armature 2 at the level of the first end region 130 of the housing 13 . The valve element 3 has a spherical end region 30 and a cylindrical guide section 31 directly connected to the spherical en...

Abstract

A solenoid valve for controlling a fluid comprising an armature, a valve member which has a dome-shaped end region and which is connected to the a mature and is movable jointly with the armature, a first guidance region being provided on the armature, and a valve body with a valve seat, with a through orifice, the valve member opening and closing the through orifice on the valve seat, and with a guide element which defines a second guidance region for guiding the valve member and which guides the valve member when the solenoid valve is open, the guide element being formed in one piece with the valve body.

Description

technical field [0001] The invention relates to a solenoid valve for controlling fluid. Background technique [0002] Various solenoid valves of different designs are known from the prior art for controlling fluids, in particular solenoid valves known as outlet valves for ABS / TCS / ESP systems in motor vehicles. During normal operation, the valve element of these solenoid valves is usually guided on the armature and through this contact in the conical valve seat of the valve body. However, deformation and / or damage to the valve element occurs in certain load states or operating states, in particular in the intermediate stroke position up to the large stroke position, wherein it can occur that the valve element can come into contact with the valve in the partial stroke position. physical contact. This can lead to impermissible damage or changes to the valve function. Contents of the invention [0003] In contrast, the solenoid valve according to the invention for controlli...
