Description

Kolben, welche in Zylindern oder Rohren laufen; besitzen als Abdichtungen Kolbenringe oder Dichtungsmanschetten. Es hat sich in der Praxis gezeigt, daß sich diese Abdichtungen, besonders bei frei beweglichen Kolben, einseitig stark abnutzen und dadurch oft ausgewechselt werden müssen. Diese Abnutzung ist dann sehr stark, wenn die Kolben in waagerechten oder schräggestellten Zylindern arbeiten oder wenn Kalben unmittelbar mit Antriebspleueln verbunden sind. Bei letzteren wirkt der schräge Angriff des Pleueldruckes einseitig auf den Kolben und ebenso auf die Abdichtungen.Pistons running in cylinders or tubes; own as seals Piston rings or sealing collars. It has been shown in practice that these seals, especially with freely moving pistons, wear heavily on one side and therefore often have to be replaced. This wear and tear is then very strong, if the pistons work in horizontal or inclined cylinders or if Kalben are directly connected to drive connecting rods. In the latter case, the incline is effective Attack of the connecting rod pressure on one side on the piston and also on the seals.

Weiterhin hat die Praxis gezeigt, daß bei Kolben, welche plastische oder unreine Massen vor sich herbewegen, ebenfalls die Kolbenabdichtungen in kurzer Zeit beschädigt und auch durch das in die Kolben und deren Zwischenräume eindringende Fördermaterial die Abdichtungen zugesetzt und zerstört werden. -Um sowohl eine Kolbenführung als auch eine Kolben- und Abdichtungsreinigung zu erreichen, wird erfindungsgemäß folgendes vorgeschlagen: Der Kolben i (Abb. i und 2 der Zeichnung), welcher sich in einem Zylinder :2 bewegt, erhält zwei oder mehr Rollenpaare 3, die den Kolben i. und damit auch die Abdichtungen 4 zentrisch im Zylinder 2 führen.Furthermore, practice has shown that pistons, which are plastic or move impure masses in front of you, likewise the piston seals in a short time Time damaged and also by the penetration into the pistons and their spaces Conveying material added to the seals and destroyed. -To both a piston guide as well as piston and seal cleaning is achieved according to the invention The following suggested: The piston i (Fig. i and 2 of the drawing), which in a cylinder: 2 moves, receives two or more pairs of rollers 3 that control the piston i. and thus also lead the seals 4 centrally in the cylinder 2.

Einseitig auf den Kolben i wirkende Kräfte, hervorgerufen vorn Eigengewicht des Kolbens oder durch ebenfalls einseitig wirkende Pleuelkräfte, werden von den Rollen aufgenommen. Es ist eine konstruktive Angelegenheit, diese Rollen fest oder federnd einzubauen. Durch diese zentrische Kolbenführung wird die Reibung der Kolben und -Dichtungen im Zylinder kräftesparend vermindert. Eine ungleiche Abnutzung der bewegenden Teile ist damit vermieden. Zum Zwecke der Kolben- und Abdichtungsreinigung erhält der Zylinder 2 an einem oder an beiden Enden, dort wo sich der Kolben in seiner Endbewegungslage befindet, eine ringförmige Spülkammer 5, welche mit einer Anzahl Löchern 6, mit dem Zylinderinnern 7, verbunden ist. .Das Reinigungsmittel, z. B. Wasser, tritt bei 8 ein, verteilt =ich in der oberen Spülkammer 9, tritt durch die Löcher 6 in die untere Spülkammer io und fließt bei i i mit den Verunreinigungen ab. Die Trennwände z2 erzeugen die beiden Spülkammern 9 und io. Die Zuführung des Reinigungsmittels, welches unter erhöhtem Druck erfolgt, kann, falls notwendig, in den Endlagen des Kolbens ein- und ausgeschaltet werden.Forces acting on one side of the piston i, caused by its own weight of the piston or by connecting rod forces also acting on one side, are controlled by the Roles added. It is a constructive matter to set these roles firmly or to be installed resiliently. This centric piston guide creates the friction between the pistons and seals in the cylinder reduced energy-saving. An uneven wear of the moving parts is avoided. For the purpose of piston and seal cleaning receives the cylinder 2 at one or both ends, where the piston is in its end position is an annular rinsing chamber 5, which with a Number of holes 6, with the cylinder interior 7, is connected. .The cleaning agent, z. B. water, occurs at 8, distributed = I in the upper rinsing chamber 9, passes through the holes 6 in the lower washing chamber io and flows at i i with the impurities away. The partition walls z2 generate the two rinsing chambers 9 and io. The feeding of the Detergent, which is carried out under increased pressure, can, if necessary, can be switched on and off in the end positions of the piston.
