ANDREAS RADOVANOVIC in ZÜRICH. Kraftschlüssiger Saugventilschluß bei Pumpen.ANDREAS RADOVANOVIC in ZURICH. Non-positive suction valve closure for pumps.

Zusatz zum Patente 134942 vom 24. Februar 1901.Addendum to patent 134942 of February 24, 1901.

Patentiert im Deutschen Reiche vom 11. Oktober 1902 ab. Längste Dauer: 23. Februar 1916.Patented in the German Empire on October 11, 1902. Longest duration: February 23, 1916.

Um bei langhubigen Pumpen mit dem im Haupt - Patent gekennzeichneten kraftschlüssigen Saugventilschluß den Plungerkopf zu stützen, wird, wie beiliegende Zeichnung zeigt, der Zylinder c als Führung in einer solchen Länge ausgebildet, daß ihn der Plungerkopf während des ganzen Hubes nicht verläßt. Für das Durchströmen der Flüssigkeit werden die Schlitze ί am Zylinder c angeordnet, die gegen den Totpunkt zu Ende des Ansaugens konisch zulaufen. Gegen Ende des Saughubes verdeckt der Plungerkopf k die konisch zulaufenden Schlitze immer mehr (wie dies die gestrichelt gezeichnete Stellung zeigt), verkleinert dadurch den Querschnitt für die aus dem Räume m in den Pumpenraum überströmende Flüssigkeit und erzeugt in in einen hydraulischen Druck, welcher, wie im Zusatz-Patent 136604 beschrieben, auf das Saugventil schließend wirkt.In order to support the plunger head in long-stroke pumps with the force-fit suction valve closure identified in the main patent, the cylinder c is designed as a guide of such a length that the plunger head does not leave it during the entire stroke, as the accompanying drawing shows. For the liquid to flow through, the slots ί are arranged on the cylinder c , which taper conically towards the dead center at the end of the suction. Towards the end of the suction stroke of the plunger head obscured k the tapered slots increasingly (as shown by the dashed line position), thereby reduces the cross-section for the m from the space into the pump chamber via flowing liquid and produces in into a hydraulic pressure which, as described in the additional patent 136604, acts on the suction valve closing.
