PATENTAMT.PATENT OFFICE.
Bei hydraulischen Pressen verursacht das Dichthalten des Prefskolbens, welcher im Cylinder durch eine Leder- oder Guttaperchamanschette abgedichtet ist, die gröfsten Schwierigkeiten. In hydraulic presses, the sealing of the pref piston, which is in the cylinder is sealed by a leather or gutta-percha point, the greatest difficulties.
Wie aus der Zeichnung ersichtlich ist, besteht die Dichtung aus zwei Manschetten von ungleichem äufseren Durchmesser, die durch einen Metallring α von einander getrennt sind.As can be seen from the drawing, the seal consists of two sleeves of unequal outer diameter, which are separated from each other by a metal ring α.
In diesem Ring befinden sich auf der unteren und inneren Fläche halbrund ausgedrehte Nuthen b b1, die als Sammelstelle für das Wasser dienen, welches die untere Manschette durchläfst. Von den Nuthen b bl aus führen kleine Löcher nach oben, die alle in der Mitte des Ringes auslaufen und das in den Nuthen angesammelte Wasser in das Innere der zweiten oberen Manschette ableiten, wodurch auch die obere Manschette zur Wirkung kommt und somit der Prefskolben vollständig abgedichtet wird. Das Ganze ist durch einen Winkelring verschlossen, der bei Bedarf ein schnelles Auswechseln der Manschetten gestattet.In this ring there are semicircular turned grooves bb 1 on the lower and inner surface, which serve as a collection point for the water that flows through the lower sleeve. From the grooves bb l small holes lead upwards, which all run out in the middle of the ring and drain the water that has accumulated in the grooves into the interior of the second upper sleeve, whereby the upper sleeve also comes into effect and thus completely seals the pref piston will. The whole thing is closed by an angle ring, which allows the cuffs to be changed quickly if necessary.
Claims (1)
Hydraulische Presse mit zwei Kolbendichtungsmanschetten, dadurch gekennzeichnet, dafs ein Ring aus Metall oder einem anderen widerstandsfähigen Material zwischen beiden Manschetten eingesetzt ist, der das Druckwasser, welches die untere Manschette durchläfst, durch eingedrehte Nuthen und eine Anzahl kleiner Löcher in das Innere der zweiten oberen Manschette abführt.Patent claim:
Hydraulic press with two piston sealing cuffs, characterized in that a ring made of metal or another resistant material is inserted between the two cuffs, which the pressurized water, which flows through the lower cuff, through screwed grooves and a number of small holes in the interior of the second upper cuff leads away.
