 die Ringaussparung n und die Verbindungsleitung r in den Arbeitszylinder der betreffenden Maschine strömt. Zum Umsteuern, also in diesem Falle zum Absperren des Druckwasser von der Maschine, wird der Steuerkolben nach oben bewegt und hiebei geht zunächst der Schutzkolben   i   an den Öffnungen p vorbei, wodurch die Durchströmung des Druckwassers aus der Leitung q in    die Leitung   r stark vermindert wird, so dass, wenn der untere Dichtungskolben mit seiner Manschette A über die   Öffiiungen p   geht, kein schädliches Durchströmen von Druckwasser gegen das Innere des Manschettenrandes nach den   Onnungan p stattfindet,   worauf nach Vorbeigang des unteren Dichtu.

   manschette g ist bei dem dargestellten Ausführungsbeispiel die Anordnung eines Schutzkolbens unnötig, da diese niemals über die ÖfInmlgen 0 tritt.

   Wenn dagegen die Steuervorrichtung nicht,   wie bei dem dargestellten Beispiel, zur Steuerung von Druckwassermaschinen mit einfachem Tauchkolben bestimmt ist, sondern wenn die Steuervorrichtung durch Vereinigung zweier Vorrichtungen oder einer vermehrten Anzahl von Rohranschlüssen für die Steuerung von Maschinen mit doppeltem Tauchkolben oder Stufenkolben ausgeführt ist, so ist entsprechend jeder Abdichtungsmanschette, die an einem   Ofnungskranz   vorbeizugehen hat, ein entsprechender Schutzkolben vorzuschalten.

 the ring recess n and the connecting line r flows into the working cylinder of the machine in question. To change direction, i.e. in this case to shut off the pressurized water from the machine, the control piston is moved upwards and the protective piston i first passes the openings p, which greatly reduces the flow of pressurized water from line q into line r , so that when the lower sealing piston with its cuff A goes over the openings p, no harmful flow of pressurized water against the inside of the cuff edge takes place after the opening p, whereupon after the lower seal u has passed.

   ngskolbens the pressurized water from the working cylinder reaches the sewer line M. When the control piston moves back into the position shown in FIG. 1, the sleeve h of the lower sealing piston is again moved past the openings p

   cuff g, the arrangement of a protective flask is unnecessary in the illustrated embodiment, since this never goes over the opening 0

   If, on the other hand, the control device is not intended to control pressurized water machines with a single plunger, as in the example shown, but if the control device is designed by combining two devices or an increased number of pipe connections for the control of machines with double plungers or stepped pistons, so a protective flask must be connected upstream of each sealing cuff that has to pass a wreath.

Claims (1)

PATENT-ANSPRUCH : Steuervorrichtung für mit Druck-wasser betriebene Arbeitsmaschinen mit Dichtungsmanschetten am Steuerkolben, dadurch gekennzeichnet, dass derjenigen Dichtungsmanschette bzw. einer Mehrzahl solcher, die die Verbindung der Druckwasserleitung mit dem Arbeitszylinder der Maschine vermittelt, ein Schutzkolben in Form eines oder mehrerer Einzelkolben vorgeschaltet ist, der das Durchströmen des Druckwasser während des Vorbeigleitens der Dichtungsmanschette an den Durchströmungsöffuungen erheblich einschränkt, um die Dichtungsmanschette gegen eine vorzeitige Zerstörung beim Vorbeigehen an den Durchgangsöffnungen durch die Druck- wasserströmung zu schützen. PATENT CLAIM: Control device for pressurized water-operated machines with sealing sleeves on the control piston, characterized in that the sealing sleeve or a plurality of such sealing sleeves which connect the pressurized water line to the working cylinder of the machine is preceded by a protective piston in the form of one or more individual pistons, which the The flow of pressurized water while the sealing sleeve slides past the throughflow openings is considerably restricted in order to protect the sealing sleeve against premature destruction when passing the through openings by the pressurized water flow.
