Description

Kugeldruckpresse für Brinellversuche nlit Ausübung der Kraft durch Druckflüssigkeit. -Wird der Kolben C durch eine Handpumpe D unter Flüssigkeitsdruck 'gesetzt und trift Flüssigkeit aus dem Pumpenraum E infolge von Undichtigkeiten am Kolbenumfang durch, so wird diese Flüssigkeit durch den Abschluß des Gehäuses mit einem elastischen Mittel, z. B. einer Gummirnembran, am Ausfließen verhindert und von Zeit zu Zeit durch öffnen eines Ventils B unter dem Einfiuß einer leichten Druckfeder und eines kleinen Kolbens F o. dgl. wieder in den Pumpenraum E zurückgeführt.Ball pressure press for Brinell tests with exertion of force through hydraulic fluid. - If the piston C is placed under liquid pressure by a hand pump D and liquid from the pump chamber E penetrates as a result of leaks on the piston circumference, this liquid is removed by closing the housing with an elastic means, e.g. B. a rubber membrane, prevented from flowing out and returned to the pump chamber E from time to time by opening a valve B under the influence of a light compression spring and a small piston F or the like.
