Zusatz zum Patente 134942 vom 24. Februar 1901.Addendum to patent 134942 of February 24, 1901.
Patentirt im Deutschen Reiche vom 14. Mai 1901 ab.
Längste Dauer: 23. Februar 1916.Patented in the German Empire on May 14, 1901.
Longest duration: February 23, 1916.
Gegenstand der Erfindung ist eine Weiterbildung der in dem Haupt-Patent beschriebenen Anordnung.The subject of the invention is a further development of the one described in the main patent Arrangement.
Fig. ι zeigt einen Längs- und Fig. 2 einen Querschnitt nach A-A, Fig. 3 ein Ventildetail. Fig. 1 shows a longitudinal and Fig. 2 shows a cross section according to AA, Fig. 3 shows a valve detail.
Der Raum m, in welchen der Plungerkopf k am Ende der Saugperiode eintritt, ist vom Pumpenraum n, in welchen sich auch das Saugventil öffnet, durch einen Cylinder a getrennt, in welchem der mit dem Saugventil verbundene Kolben a' spielt.The space m, in which the plunger head k enters at the end of the suction period, is separated from the pump space n, in which the suction valve also opens, by a cylinder a in which the piston a ' connected to the suction valve plays.
Der hydrauliche Druck, welcher beim Eindringen des Plungerkopfes k in die Bohrung c erzeugt wird, drückt gegen den Kolben a' und prefst dadurch das Saugventil s an seinen Sitz. Das Saugventil wird daher nicht durch einen direct über ihm wirkenden Druck, sondern vermittelst des Kolbens a', welcher den im Räume m entstandenen . hydraulischen Druck aufnimmt, geschlossen. Es entsteht also über dem Saugventil beim Schliefsen kein hydraulischer Druck, so dafs ein Ansaugen auch noch während der Schliefsbewegung des Saugventils stattfinden kann.The hydraulic pressure, which is generated when the plunger k penetrates into the bore c , presses against the piston a ' and thereby prefers the suction valve s to its seat a ', which is the result of the space m . absorbs hydraulic pressure, closed. There is therefore no hydraulic pressure over the suction valve when it closes, so that suction can also take place during the closing movement of the suction valve.
Der Kolben a! kann mit dem Saugventile entweder starr (Fig. i) oder elastisch (Fig. 3) verbunden sein. Gegen das Auftreten eines übermäfsigen Druckes oder eines Vacuums im Räume m sind, wie nach dem Haupt-Patent, im Plungerkopf entgegengesetzt öffnende Ventile ν und v' angeordnet. Die Saugventilachse kann gegen die Plungerachse eine beliebige Lage einnehmen.The piston a! can be connected to the suction valve either rigidly (Fig. i) or elastically (Fig. 3). Against the occurrence of an excessive pressure or a vacuum in the space m , as according to the main patent, oppositely opening valves ν and v ' are arranged in the plunger head. The suction valve axis can assume any position against the plunger axis.
Claims (1)
Kraftschlüssiger Saugventilschlufs mit hydraulischem Druck nach Patentschrift 134942, dadurch gekennzeichnet, dafs der beim Eintritt des Plungerkopfes k in den Raum m erzeugte hydraulische Druck auf einen mit dem Saugventil verbundenen Kolben a! wirkt, welcher in einem Cylinder α spielt, der den Raum m vom Pumpenraume η trennt und so das Saugventil schliefst, ohne dafs direct über demselben ein hydraulischer Druck auftritt.Patent claim:
Non-positive suction valve connection with hydraulic pressure according to patent specification 134942, characterized in that the hydraulic pressure generated when the plunger head k enters the space m acts on a piston a connected to the suction valve! acts, which plays in a cylinder α , which separates the space m from the pump space η and thus closes the suction valve without any hydraulic pressure appearing directly above it.
