AI Technical Summary

Problems solved by technology

Since even a valve stem cannot be produced as a perfectly symmetrical component at reasonable cost and therefore has different material properties or dimensional deviations on its circumference, such differences can also have a negative effect on the function of the valve

Embodiment Construction

[0019] The electromagnetically actuatable valve 10 shown in longitudinal section in FIG. 1 has a pressure-limiting effect and is used in vehicle brake systems with slip adjustment, such as anti-lock brake protection and / or drive slip adjustment. The valve 10 has an elongated valve housing 11 in which a longitudinal bore 12 is arranged. The longitudinal bore 12 has a plurality of longitudinal grooves 14 in an outflow point 13 , of which only one longitudinal groove 14 is visible in FIG. 1 . The valve housing 11 is connected to a valve connection element 15 on the end side on the side facing the outflow point 13 . The valve connection element 15 has an inlet 16 for pressure medium and a non-return valve 18 . On the side facing the valve housing 11 , an annular return point 19 is provided, which interacts with the longitudinal groove 14 and is surrounded on the peripheral side together with the valve housing 11 by a radial filter element 20 . A pot-shaped valve body 22 is fitte...

Abstract

An image display apparatus is disclosed that includes an image input unit configured to input plural images, a display image selection unit configured to select an image to be displayed from the images input by the image input unit, an image display unit configured to display the image selected by the display image selection unit, and an interest level recognition unit configured to determine whether an interest level of a user is high / low. The display image selection unit is configured to select the image to be displayed based on a determination result of the interest level recognition unit pertaining to the interest level of the user.

Description

technical background [0001] The invention relates to an electromagnetically actuatable valve according to the preamble of claim 1, in particular for use in a braking system of a motor vehicle. [0002] An electromagnetically actuatable valve of this type is known and has a rotationally symmetrical armature, which rests with an end face on a valve plunger of a valve closing member on the actuating seal seat. Since an armature of this type is practically produced at a reasonable cost without rotational symmetry, the armature therefore has different magnetic properties and shape properties over the circumference, which directly or indirectly affect the accuracy of the valve function. . These properties are, for example, locally varying material properties, which have a corresponding influence on the magnetic function. There are also run-out deviations from the plunger on the end face, which have an effect on the position of the plunger on the valve seat. Furthermore, fluctuati...
