Die Erfindung bezieht sich auf eine druckmittelgetriebene Schubkolbenpumpe mit einander gegen-, überliegenden Pumpenräumen, bei der der Schübkolben als auf einem ortsfesten Kolben hin- und hergleitender Zylinder ausgebildet ist, welcher ortsfeste Kolben eine mit einem in der Längsachse des Schubkolbens angeordneten Hauptsteuerschieber ausgerüstete Schiebersteuerung aufweist, die mit den inneren Begrenzungsflächen der Schubkolbenköpfe zusammenarbeitet. The invention relates to a pressure-medium-driven push piston pump with one another, overlying pump chambers, in which the thrust piston slides back and forth on a stationary piston Cylinder is formed, which stationary piston one with one in the longitudinal axis of the thrust piston arranged main control slide valve control equipped with the inner Boundary surfaces of the piston heads cooperates.

Eine derartige Schubkolbenpumpe betrifft der Gegenstand der Patentanmeldung P 12 67 983.3-15 (deutsche Auslegeschrift 1267 983). Bei dieser Schubkolbenpumpe ist der Hauptsteuerschieber als Drehschieber ausgebildet.Such a thrust piston pump relates to the subject of patent application P 12 67 983.3-15 (German interpretation 1267 983). In this piston pump, the main control spool is as Rotary valve formed.

Der Erfindung liegt die Aufgabe zugrunde, den Gegenstand der Hauptpatentanmeldung in der Konstruktion und somit fertigungstechnisch zu vereinfachen und eine Schiebersteuerung zu schaffen, die auch nach langer Betriebsdauer nicht störanfällig ist.The invention is based on the object of the main patent application in the construction and thus to simplify production engineering and to create a slide control that is not susceptible to failure even after a long period of operation.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der Hauptsteuerschieber als vom Antriebsmedium für den Schubkolben durchflossener Stufenkolben ausgebildet ist.According to the invention, this object is achieved in that the main control slide is a stepped piston through which the drive medium for the thrust piston flows is trained.

Zur Erzielung einer gedrängten Bauweise ist es vorteilhaft, in dem Hauptsteuerschieber einen Zuflußkanal und einen Abflußkanal vorzusehen, deren Zufluß bzw. Abflußöffnung in der Längsachse des Schubkolbens liegen.To achieve a compact design, it is advantageous to have an inflow channel in the main control slide and to provide a drainage channel, the inflow or outflow opening in the longitudinal axis of the Thrust piston lie.

Um die Strömungsverluste gering zu halten, entspricht der Durchmesser der Zufluß- und der Abflußöffnung der lichten Weite des Zuflußkanals und des Abflußkanals.In order to keep the flow losses low, the diameter of the inflow and the outflow opening corresponds the clear width of the inflow channel and the outflow channel.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt. Es zeigtAn embodiment of the invention is shown in the drawings. It shows

The drive medium is supplied via the inflow channel 3, flows partially through the interior of the main control slide 4, namely the chamber 5 and reaches the in F i g. 1 position shown on the Channel 6, the bore 7 and the channel 8 in the cylinder space 9. In this cylinder space is a Pressure built up by which the thrust piston is moved in the direction of arrow 10.

as Anschlag 18 des Vorsteuerschiebers 19 zusammen. Der Vorsteuerschieber wird umgeschaltet. Durch diese Bewegung des Vorsteuerschiebers wird die Steuerkammer 20 des Hauptsteuerschiebers 4 auf Zufluß geschaltet. Der Zufluß erfolgt über die Leitung 21, den Ringraum 22 und die Leitung 23. Da die Steuerkammer 24 ständig über die Bohrungen 25 und 26 mit dem Abfluß 15 in Verbindung steht, wird der Hauptsteuerschieber in die andere Endstellung bewegt. Hierdurch wird der Abflußkanal 14 mit der Bohrung 27 verbunden und der Zylinderraum 9 auf Abfluß geschaltet. Das Antriebsmedium fließt nun über den Kanal 6, die Bohrung 28 und den Kanal 29 in den Zylinderraum 11. Der Schubkolben bewegt sich in Richtung des Pfeiles 30. Am Ende dieser Hubbewegung arbeitet die innere Begrenzungsfläche 31 des Schubkolbenkopfes 32 mit dem Anschlag 33 des Vorsteuerschiebers 19 zusammen. Der Vorsteuerschieber wird wieder in F i g. 2 aufgezeigte Stellung bewegt. In dieser Stellung ist die Steuerkammer 20 über die Bohrung 23, den Ringraum 22 und den Kanal 34 mit dem Abfluß 15 verbunden. Infolge des Druckes in der Zuflußleitung wird der Haupsteuerschieber in die in den F i g. 1 und 2 aufgezeigte Stellung bewegt.

The pilot spool is switched over. This movement of the pilot spool is the Control chamber 20 of the main control slide 4 switched to inflow. The inflow takes place via the pipe 21, the annular space 22 and the line 23. Since the control chamber 24 continuously via the bores 25 and 26 is in communication with the drain 15, the main control slide is in the other end position emotional. As a result, the discharge channel 14 is connected to the bore 27 and the cylinder chamber 9 opens Drain switched. The drive medium now flows through the channel 6, the bore 28 and the channel 29 into the cylinder chamber 11. The thrust piston moves in the direction of the arrow 30. At the end of this The inner limiting surface 31 of the piston head 32 works with the stop 33 in the stroke movement of the pilot valve 19 together. The pilot valve is shown again in FIG. 2 position shown emotional. In this position, the control chamber 20 is through the bore 23, the annular space 22 and the Channel 34 connected to the drain 15. As a result of the pressure in the supply line, the main control slide becomes in the in the F i g. 1 and 2 position shown moved. By the grub screw 35, whose cylindrical bolt 36 protrudes into a groove 37 of the main control slide 4, becomes the main control slide secured against rotation.
