Problems solved by technology

At the same time, practice has shown that in relatively large passage openings in sheet metal backing layers, when exposed to strong pulse pressures passing through the screen in only one direction or to passing through the screen in two In the case of fluids with significantly different pressures in different directions, the area of ​​the screen affected by these flows is stretched in the direction of the passage, so that the open area of ​​the screen increases in the passage opening and, therefore, it is no longer possible to capture the desired all particles
Due to the more extreme stretching of the sieve layer in the region of the passage openings, there is the danger that individual threads of the sieve break

Embodiment Construction

[0053] Figure 1 shows a control system according to the prior art, a partial Figure 1-a A top view of the middle board 101 of the control system is provided. partial Figure 1-b A section through two channel guides 102 , 103 and an intermediate plate 101 arranged between them is shown in a sectional view. Regarding the middle plate 101, Figure 1-b The section shown in the corresponding Figure 1-a Section A-A in. Figure 1-c Focusing only on the middle plate 101 and showing in detail the middle plate 101 in Figure 1-b The area highlighted by the dashed box in .

[0054] From FIG. 1 it becomes clear that the intermediate plate 101 comprises a plurality of passage openings, wherein the passage openings 113 for fastening members and the passage openings 111 , 112 for fluids can be different from each other, the intermediate plate 101 via the passage The opening 113 is connected to the channel guide 102 , 103 or via the channel guide 102 , 103 to an additional component. ...

Abstract

The invention relates to a control system with at least two channel-guiding parts (2, 3) and an intermediate plate arranged between the two channel-guiding parts (2, 3). The intermediate plate (1) comprises at least two flat metallic gasket layers (5, 7) as well as a screen layer (4) arranged between the at least two facial metallic gasket layers (5, 7). In the intermediate plate (1), one or several fluid passage openings (11) are formed, which pass through the flat metallic gasket layers (5, 7) so that they form passage openings. These passage openings are spanned by the screen layer (4). This control system is characterized in that in at least one of said one or several fluid passage openings (11) at least one support arrangement (41) for the screen layer (4) is formed in the flat metallic sealing layer (5, 7) adjoining to the screen layer (4).

Description

technical field [0001] The invention relates to a control system having at least two channel guides and an intermediate plate arranged between the two channel guides. The intermediate plate includes at least two flat metal backing layers and a screen layer arranged between at least two surface metal backing layers. In the intermediate plate, one or more fluid passage openings are formed which pass through the flat metal backing layer so that they form passage openings. These passage openings are spanned by the screen layer. The sieve layer acts primarily as a filter to catch particles which might not be carried into the channel guides, where they could thus cause blockages and malfunctions. The screen layer is not intended to be a replaceable filter system, but rather a permanently installed element that is used throughout the system except for another filter system that can be replaced and emptied. The control system is especially intended for use in hydraulic transmission...
