Diese Dichtungsarten haben den Nachteil der Eintrocknung oder einer baldigen Ab arbeitung neben mangelhafter Schmierung.
Durch die Erfindung sollen diese Mängel beseitigt werden.
Fig. 1 stellt den Schnitt durch die Stulpe nach A-B der Fig. 2 und Fig. 2 die Draufsicht auf den Kolben dar.
Die Blechkolbenmanschette a ist zwecks Erzeugung einer Labyrinthdichtung und gleichzeitig zur Herbeiführung einer elastischen Dichtung sowie zur Aufnahme und Abgabe des Schmierfettes mit kurzen Falten b versehen, die in der Wand der Manschette von oben nach unten verlaufen. Jede Falte b gehört einer Welle c an, die um die Manschette herumläuft. Hiebei nehmen die durch die Falten gebildeten Vertiefungen das Schmier' fett auf, während die nach aussen hervorstehenden Erhöhungen die Federung der Kolben. manschette nach aussen (elastische Dichtung) bewirken.

Spring-loaded and self-lubricating piston seal sleeve made of sheet metal.
The aim of the invention is to provide pistons, in particular for piston pumps, with a self-lubricating seal that is always usable and always closes well.
In the case of the pump pistons in use up to now, the
EMI1.1
These types of seals have the disadvantage that they dry out or that they will soon be processed in addition to poor lubrication.
The invention aims to overcome these deficiencies.
Fig. 1 shows the section through the cuff according to A-B of Fig. 2 and Fig. 2 shows the top view of the piston.
The sheet metal piston sleeve a is provided with short folds b in the wall of the sleeve from top to bottom in order to produce a labyrinth seal and at the same time to produce an elastic seal and to receive and dispense the lubricating grease. Each fold b belongs to a wave c which runs around the cuff. The indentations formed by the folds receive the lubricating grease, while the protrusions protruding outwards take up the suspension of the pistons. effect the sleeve to the outside (elastic seal).
