Description

Gegenstand der Erfindung ist ein Kolbe nschilber, der aus beliebigen Werkstoffen für beliebige Zwecke gefertigt werden kann, der aber hauptsächlich für solche Anwendungsfälle bestimmt ist, in denen korrosionsfeste Werkstoffe, wie Graphit; imprägnierte Kohle, keramische Stoffe oder Kunststoffe, verwendet werden müssen.The invention is a Kolbe nschilber, which consists of any Materials can be manufactured for any purpose, but mainly for such applications are intended in which corrosion-resistant materials such as graphite; Impregnated carbon, ceramics, or plastics must be used.

Bei dem Kolbenschieber gemäß der Erfindung wird die Abdichtung zwischen Kolbenschaft und Bohrung dadurch bewirkt, daß auf den Schaft zwei Manschetten aufgeschoben sind, deren Spreizung durch eine ebenfalls auf den Schaft aufgeschobene Büchse hervorgerufen wird. Zu diesem Zweck ist der Schaft an seiner Spindelseite mit einer Gewindehülse versehen, und diese Hülse preßt die Manschetten mit der Büchse gegen einen Bund am anderen Schaftende.In the piston valve according to the invention, the seal is between The piston skirt and bore are caused by two collars being pushed onto the skirt are, the expansion of which is caused by a sleeve also pushed onto the shaft will. For this purpose, the shaft is provided with a threaded sleeve on its spindle side provided, and this sleeve presses the sleeves with the sleeve against a collar at the other end of the shaft.

Ein derartiger Kolbenschieber wird durch die Zeichnung näher veranschaulicht. Der aus imprägnierter Kohle hergestellte Schieberblock i trägt die Bohrung ja für den Zufluß und die Bohrung ib für den Abfluß des abzusperrenden Mediums. Auch der Kolbenschaft 2 in der Bohrung ja besteht aus imprägnierter Kohle, desgleichen die Büchse 3, während die -NSanschetten 4a und 4b, welche die ei- entlichen Dichtungskörper darstellen, aas elasti:ciiere;n Material, beispielsweise aus, ener Mischung von Kautschuk und Graphit, hergestellt sind. Auf den Schaft ist die Hülse 5 aufgeschraubt; durch den Schraubdruck wird die untere Manschette 4b gegen den Bund 211 am unteren Schaftende angepreßt, und die Spreizteile der beiden Manschetten legen sich dicht an Schaft und Bohrung an. Nachdichtungen lassen sich dadurch ermöglichen, daß man die Bohrung mit Vorsprüngen,- auf die sich die untere Manschette in der Schlidstellung des Schiebers aufsetzt, versieht, am einfachsten in der Weise, daß man die Bohrweite unten etwas enger wählt.Such a piston valve is illustrated in more detail by the drawing. The slide block i made of impregnated carbon carries the bore for the inflow and the bore ib for the outflow of the medium to be shut off. Also the Piston skirt 2 in the bore is made of impregnated carbon, as does the Sleeve 3, while the -NS collars 4a and 4b, which are the individual sealing bodies represent, aas elastic: ciiere; n material, for example from, a mixture of Rubber and graphite. The sleeve 5 is screwed onto the shaft; by the screw pressure, the lower cuff 4b is against the collar 211 on the lower Shaft end pressed on, and the expansion parts of the two cuffs are tight on the shaft and bore. Re-seals can be made possible by the fact that the hole with projections, - on which the lower collar rests in the closed position of the slide touches down, the easiest way to do this is to determine the drilling width choose a little closer below.

PATENTANSPRÜCHE: i. Kolbenschieber, dadurch gekennzeichnet, daß zur Abdichtung zwischen Kolbenschaft und Bohrung auf den Schaft zwei Manschetten mit die Spreizung bewirkender -Büchse aufgeschoben sind und daß der Schaft an seiner Spindelseite mit einer Gewindehülse versehen ist, welche die Manschetten mit der Büchse gegen einen Bund am anderen Schaftende preßt. PATENT CLAIMS: i. Piston valve, characterized in that two sleeves with the expansion-causing sleeve are pushed onto the shaft to seal between the piston shaft and the bore and that the shaft is provided on its spindle side with a threaded sleeve which connects the sleeves with the sleeve against a collar at the other end of the shaft presses. 2. Kolbenschieber nach Anspruch i, dadurch gekennzeichnet, daß die Bohrung Vorsprünge aufweist, auf die sich die untere Manschette in der Schließstellung des Schiebers aufsetzt.2. Piston valve according to claim i, characterized in that the bore has projections on which the lower cuff touches down in the closed position of the slide.
