Embodiment Construction

[0041] as from Figure 1 to Figure 9 It can be seen that the illustrated embodiments of the valve assembly 1 according to the invention each comprise a valve body 3 , 3A, 3B, 3C in which a fluid channel 7 is formed connecting the fluid inlet FE with the fluid outlet FA. The closing body 10 , which is movably mounted in the fluid channel 7 , is acted upon with a prestressing force FVS in the direction of the valve seat 5 formed in the valve body 3 , 3A, 3B, 3C, wherein the fluid force FF acts against the prestressing force FVS. Closing body 10 to open valve seat 5. In this case, the closing body 10 is guided axially and / or radially by at least one guide ball 12 . Furthermore, at least one guide ball 12 is arranged between the closing body 10 and the lateral boundaries of the fluid channel 7 .

[0042] as from Figure 1 to Figure 9 It can also be seen that the pretensioning force FVS acts on the closing body 10 at an angle via at least one guide ball 12 and that the at least ...

Abstract

The invention relates to a valve assembly (1), comprising a valve body (3) in which a fluid channel (7) is formed that connects a fluid inlet (FE) to a fluid outlet (FA), wherein a preload force (FVS) is applied to a closing body (10), which is movably mounted in the fluid channel (7), in the direction of a valve seat (5) formed in the valve body (3), a fluid force (FF) acting on the closing body (10) against the preload force (FVS) in order to open the valve seat (5). The closing body (10) is guided axially and / or radially by at least one guide ball (12), the guide ball (12) being arranged between the closing body (10) and a lateral boundary of the fluid channel (7).

Description

technical field [0001] The invention relates to a valve assembly of the type according to independent claim 1 . Background technique [0002] Known vehicle braking systems with ABS and / or ESP functions provide additional functions, for example to support the driver when maintaining a distance from a vehicle driving ahead. This is due to the fact that the additional function actively intervenes in the vehicle's braking system by building up pressure at the wheel brake calipers without the driver having to actuate the brake pedal himself. In order to prevent the driver from hearing disturbing noises, hydraulic damping measures are used which reduce pressure pulsations from the devices of the delivery unit of the vehicle brake system. Damping measures can consist of hydraulic resistance and capacity. For the effectiveness of such hydraulic shock absorbers, a large throttling through hydraulic resistance is used. Here, it can be regarded as a disadvantage that, with the high ...
