Description

Es sind Ringvehtile mit Lenkerführung bekannt, bei welchen die Lenker der Vientilplatte nicht unmittelbar am Ventilsitz oder Ventilfänger, sondern an gleichartigen. Lenkern der S Fängerplatte befestigt sind. Bei diesen Ventilen wird eine außerordentliche Hubhöhe erzielt. Ein Nachteil derselben besteht aber darin, daß die Ventilplatte wohl in geöffnetem Zustand genau, in der Schließstellung dagegenThere are ring valves with handlebars known, in which the links of the valve plate are not directly on the valve seat or valve catcher, but on similar ones. The handlebars of the S catcher plate are attached. With these valves an extraordinary lifting height is achieved. A disadvantage of this is, however, that the valve plate is probably exactly in the open position, but in the closed position

ίο weniger genau geführt ist. In der Öffnungsstellung liegen nämlich die Lenker mit den Platten in einer Ebene und stellen so einer seitlichen Verschiebung der Ventilplatte den größten Widerstand entgegen. In der Schließstellung dagegen sind die Lenker am weitesten aus der Ebene der Platten herausgebogen. In dieser Betriebsstellung ist aber zur Erzielung einer gleichbleibend guten Abdichtung im Dauerbetrieb eine möglichst genaue Führung der Ventilplatte erwünscht.ίο is less precisely guided. In the open position namely are the handlebars with the plates in the same plane and thus provide one lateral displacement of the valve plate counteracts the greatest resistance. In the closed position on the other hand, the links are bent furthest out of the plane of the plates. In this operating position, however, is to achieve a consistently good seal In continuous operation, the most precise possible guidance of the valve plate is desired.

Gegenstand der Erfindung ist ein Ringventil mit aus der Ventilplatte konzentrisch zur Mitte ausgeschnittenen Lenkern, bei welchem der vorbeschriebene Nachteil beseitigt ist. Die Erfindung besteht darin, daß die Lenker mit den freien Enden gleichartiger Lenker einer zwischen Ventilplatte und Ventilsitz angeordneten Federplatte fest verbunden sind. Bei dieser Anordnung ist die Ventilplätte in ihrer Schließstellung vollkommen genau geführt. '" The subject of the invention is a ring valve with links cut out concentrically to the center of the valve plate, in which the above-described disadvantage is eliminated. The invention consists in that the links are firmly connected to the free ends of similar links of a spring plate arranged between the valve plate and the valve seat. With this arrangement, the valve plate is completely precisely guided in its closed position. '"

In der Zeichnung ist als Beispiel eine Ausführungsform der Erfindung dargestellt. Es zeigen:In the drawing, an embodiment of the invention is shown as an example. It demonstrate:

Fig. 3 einen senkrechten Schnitt durch das zusammengesetzte Ventil. In der linken Hälfte ■ befindet sich die Ventilplatte in der Verschlußlage, während sie rechts in geöffnetem Zustand dargestellt ist.Fig. 3 is a vertical section through the assembled valve. In the left half ■ the valve plate is in the closed position, while it is on the right in the open state is shown.

Die Ventilplatte 1 besteht aus mehreren konzentrischen Ringen, von denen der innere zur Bildung der die freie Mittelöffnung 2 umschließenden Lenker 3 aufgeschnitten ist. Diese Lenker 3 können gegebenenfalls zur Erhöhung ihrer Biegsamkeit auf dem größten Teil 4 ihrer Länge eine etwa durch Abschleifen erzielte geringere Stärke aufweisen als die übrigen Teile der Ventilplatte 1. Auch kann aus dem gleichen Grund die Breite der Lenker 3 geringer sein, wobei dann vorteilhaft die freien Enden 5 derselben zur Erzielung einer hinreichend großen Fläche für die Befestigung an der Federplatte 6 (Fig. 2) etwas in die freie Mittelöffnung 2 vorspringen.The valve plate 1 consists of several concentric rings, of which the inner one to form the free central opening 2 enclosing Handlebar 3 is cut open. This link 3 can optionally be used to increase their flexibility over most of their length 4 achieved approximately by grinding have less thickness than the other parts of the valve plate 1. Also can be made of the same reason the width of the handlebars 3 may be smaller, then advantageously the free ends 5 of the same to achieve a Sufficiently large area for attachment on the spring plate 6 (FIG. 2) protrude somewhat into the free central opening 2.

Die Ventilplatte 1 ist an der Federplatte 6 befestigt, die mit Lenkern 7 ausgestattet ist, die beispielsweise konzentrisch den nabenförmigen "Mittelteil 8 umgeben. Auch diese Lenker 7 mit ihren freien Enden 9 können ähnlich ausgebildet sein wie die Lenker 3The valve plate 1 is on the spring plate 6 attached, which is equipped with links 7, for example concentrically the hub-shaped "Surround the middle part 8. These links 7 with their free ends 9 can also be designed similarly to the handlebars 3

Claims

the valve plate .. In particular, so can the handlebars 7 possibly all over. Length with the exception of the free end 9 be made somewhat narrower or even thinner.

The connection of the valve plate 1 with the Spring plate 6 is made in such a way that the ends 5 of the former to the ends of the the latter placed and then, for example, by spot welding to the punctured by the Circles 10 indicated locations are attached to each other. But it can be sent to the Make 10 openings punched out or be drilled, through which then for connection, for example screws or rivets r.r (Fig. 3) are performed.

The assembled valve (Fig. 3) consists of the valve seat 12, in which the through-slots 13 are arranged and in the center of which the bolt 14 is located Valve plate 1 is connected. The spring plate rests in a veras deep ling 15 surrounding the bolt 14, so that the links of the valve plate attached to the top of the spring plate are exactly with the latter if the valve is in the left position in FIG illustrated closing position is located on the hub portion of the spring plate 6 rests a ring 16, 'the distance of the capture plate tj yon "DENV valve seat 12 ensures .. the all parts can be fixed against each drawn through a not shown in the drawing screw wördiem.

If the valve plate is connected to the catcher plate by rivets 11, recesses 18 and 19 are expediently provided in the valve seat 2 and in the catcher plate 17, into which the rivets n on the ends of the valve plate enter! can. In addition, if necessary; a. -Parallel to the bolt 14, guided pin be provided, the shower grips the opening 20 of the spring plate 6 and into a correspondingly arranged bore of the valve seat 12-. enough. This creates a _; Rotation of the parts against each other while the valve is working is prevented.

As already mentioned, the above-described design of the valve results in the closed position, the lowest possible construction height of the handlebar assembly ·, the a precise guide of the plate ι in this secures decisive moment.

If the valve plate swings into the opening position shown on the right in FIG. plate sets, the handlebars are 3 of the valve plate and so the arm 7 of the spring plate from their position flat S-shaped ago & usgebogiein., with no appreciable stresses occur at the connection location 10. Furthermore, the abovementioned valve construction results in vain great durability also for the reason that the connecting points of the links can swing out at the moment of the opening stroke. Bending of the spring plate 6 is prevented with certainty given the considerable overall length of the link 3, 7.

A particular advantage of the new valve is that the concentric center pin 14 surrounding handlebar 3 have only a very small diameter, so that so only a small part of the air passage slots 13 required footprint of the valve is lost.

⁴ J. Ring valve with links cut out from the valve plate concentrically to the center, characterized in that the links (3) with the free ends (9) are identical links. (7) a spring plate (6) arranged between the valve plate (1) and the valve seat (12) are firmly connected.

2. Ring valve according to claim 1, characterized characterized in that the spring plate (6) in the closed position of the valve in a Recess (15) of the valve seat. (12) and the valve plate (1) is therefore in one plane with its links (3}.
