Abstract
(DE)
Die Erfindung betrifft ein Ventilbauteil (1, 12, 17, 29, 34, 43, 46, 48), insbesondere für einen Kolben oder ein Ventil, umfassend mindestens ein erstes scheibenförmiges Fügeteil (2, 3, 17, 24, 28, 33, 45) und mindestens ein zweites scheibenförmiges Fügeteil (2, 3, 17, 24, 28, 33, 45), wobei das erste und zweite Fügeteil (2, 3, 17, 24, 28, 33, 45) mindestens eine Öffnung (4, 5, 14, 15, 27, 37) aufweist und wobei nach einem Fügen der Fügeteile (2, 3, 17, 24, 28, 33, 45) die Öffnung (4, 5, 14, 15, 27, 37) der Fügeteile (2, 3, 17, 24, 28, 33, 45) derart zusammenwirkt, dass ein Kanal gebildet ist und ein fluides Mittel, insbesondere ein Öl, durch den Kanal (6, 16, 39) gebildet ist und eine fluides Mittel durch den Kanal (6, 16, 39) hindurch strömbar ist und wobei in einem ersten Bereich des ersten Fügeteils (2, 3, 17, 24, 28, 33, 45) eine zumindest teilweise umlaufende Erhöhung (9, 19, 25, 30, 35) und/oder Vertiefung (10, 20, 26, 32, 36) und in einem dem ersten Bereich gegenüberliegenden zweiten Bereich des zweiten Fügeteils (2, 3, 17, 24, 28, 33, 45) eine zumindest teilweise umlaufende Erhöhung (9, 19, 25, 30, 35) und/oder Vertiefung (10, 20, 26, 32, 36) vorgesehen ist, wobei die Erhöhng (9, 19, 25, 30, 35) und/oder die Vertiefung (10, 20, 26, 32, 36) nach dem Fügen der Fügeteile abdichtend zusammenwirken.
(EN)
The invention relates to a valve component (1, 12, 17, 29, 34, 43, 46, 48), in particular for a piston or a valve, comprising at least one first disk-shaped joining part (2, 3, 17, 24, 28, 33, 45) and at least one second disk-shaped joining part (2, 3, 17, 24, 28, 33, 45), wherein the first and second joining parts (2, 3, 17, 24, 28, 33, 45) have at least one opening (4, 5, 14, 15, 27, 37), and wherein, once the joining parts (2, 3, 17, 24, 28, 33, 45) have been joined, the opening (4, 5, 14, 15, 27, 37) in the joining parts (2, 3, 17, 24, 28, 33, 45) interacts in such a way that a channel is formed and a fluid medium, in particular an oil, is formed through the channel (6, 16, 39) and a fluid medium can flow through the channel (6, 16, 39), and wherein, in a first region of the first joining part (2, 3, 17, 24, 28, 33, 45), an at least partially peripheral elevation (9, 19, 25, 30, 35) and/or depression (10, 20, 26, 32, 36) and, in a second region of the second joining part (2, 3, 17, 24, 28, 33, 45), said second region being opposite the first region, an at least partially peripheral elevation (9, 19, 25, 30, 35) and/or depression (10, 20, 26, 32, 36) are provided, wherein the elevation (9, 19, 25, 30, 35) and/or the depression (10, 20, 26, 32, 36) interact with one another in sealing fashion once the joining parts have been joined.
