Embodiment Construction

[0020] A fundamental aspect of the invention consists in the embodiment of a status display unit in any type of fluid technology device. Embodiments are described with reference to a valve arrangement 1 for controlling fluid flow, but should not be limited thereto. Examples of further fluid-technical devices for realizing the invention are vacuum generators, maintenance devices for producing compressed air, or also drives such as rotary and linear drives. The following basic description applies generally to all types of fluid technology devices.

[0021] The valve device 1 comprises, for example, a plate-shaped valve seat 2 which is also divided according to requirements, and which is penetrated by a plurality of valve seat passages 3, and these valve seat passages 3 are in the figure 2 Partially shown only in dashed lines. The valve seat 2 defines a mounting surface 4 on which a plurality of electrically actuatable valve units 6 arranged one behind the other in the directi...

Abstract

This is a fluid-technical assembly having a state display unit (23) which has a light source (24) which is arranged in a concealed manner in the assembly, and an optical waveguide (25) which guides the light signals to a display region (26). The light source (24) emits polychromatic light which is filtered by a colour filter (42) in such a way that a defined visible light colour appears in the display region.

Description

technical field [0001] The invention relates to a fluidic device having at least one status display unit comprising a light source concealed in the device and an optical conductor which guides the light signal of the light source to a display area on the outside of the device. Background technique [0002] A fluid technology device of this type designed as a valve device is known from DE 201 05 982 U1. It comprises a plurality of interconnected valve units that can be operated electrically, and the operating state of the valve units is visually displayed by a status display unit. A printed circuit board is provided on the housing mounted end-face to the valve unit arrangement, which carries a plurality of light-emitting diodes, from which a light conductor leads in each case to a display area on the outer side assigned to the valve arrangement. The light signals emitted by the light-emitting diodes are guided by associated light guides to the display area, wherein the light...
