Description

Steuerung für druckluftbeaufschlagte Arbeitszylinder, vornehmlich für Weichenstellvorrichtungen des Untertagebetriebes Das Patent 756 137 betrifft Bine Steuerung für druckluftbeaufschlagte Arbeitszylinder, vornehmlich für Weichenstellvorrichtungen des Untertagebetrie#bes, unter Benutzung eines im Steuergehâuse fliegend gelagerten Kolbenschiebers, dessen beide Kolbenflâchen dauernd mit Druckl.uft beaufschlagt und gleich groB sied, wâhrend die zwecks Umsteuerung wechselweise zu dffnenden Entlastungsbohrungen der Arbeitsrüume des Kolbenschiebers ihrem Durchmesser nach grüBer ausgebildet sind als die dauernd gedffneten und gedrosselfén EinlaBbohrungen des Betriebsmittelsdamit wird bei vorübergehender Entlastung des einen Kolbenraumes durch ein von auBen betâtigtes AbschluB-organ trotz der dauernd nachstrdmenden Frischluft, derKolbenschieber unter derBelastung,der anderen Kolbenseite augenblicklich umgesteuert. Hierdurch wird dann nach dem Hauptpatent die Beaufschlagung des eigentlichen Arbeitszylinders gesteuert, wobei auch immer der vorgeschaltete Kolbenschieber die andere Seite dieses Arbeitskolbens mit dem Auspuff verbirndet.Control for working cylinders pressurized with compressed air, primarily for turnout machines in underground operations. Patent 756,137 relates to Bine control for working cylinders pressurized with compressed air, primarily for point setting devices of the underground mine, using an overhung in the control housing Piston valve, the two piston surfaces of which are continuously pressurized with compressed air and the same amount of boiling, while the relief bores to be opened alternately for the purpose of reversing the working spaces of the piston valve are designed to be larger in diameter than the continuously open and throttled inlet bores of the equipment is temporarily relieved of pressure in one piston chamber by an externally actuated one Closing organ despite the constant inflow of fresh air, the piston valve underneath the load on the other side of the piston is reversed immediately. This will then the application of the actual working cylinder is controlled according to the main patent, where the upstream piston valve is always the other side of this working piston connected to the exhaust.

Das Patent 885 247 betrifft nun eine weitergehende Vereinfachung dieser Anordnung insofern, The patent 885 247 now relates to a further simplification of this arrangement insofar as

Claims (1)
Verbindungsstange der Kolbenschieber (51, 52) eingreifender Ansatz (56) des jochs (4i), vorgesehen ist, durch die bei einem anf5,nglichen Steckenbleiben .des Steuerkolbens (5i,52) die Umsteuerung mechanisch erzwungen wird. 4. Steuerung nach Anspruch i, dadurch gel;ennzeichnet, dafl die Umschaltung durch den Umsteuer- bzw. Arbeitskolben selbst durchgeführt wird, indem den schieber- Oder ventilartig wirkenden Kolbenkdrpern (32' bzw. 32") die Anschlüsse (53,54) zum Betâtigungskontakt (55) so zugeordnet werden, daB sie abwechselnd von den Kolben (32', 32") ge8ffnet bzw. geschlossen werden. 5. Steuerung nach den Ansprüchen i und 2, dadurch gekennzeichnet, daB in dem mit den Arbeitsr5.umen vor den Kolben (32' bzw. 33') verhundeneri Schiebergeh5,use (5o) sich ein dreiteiliger Kolbenschieber (5 i, 52, 56) bewegt, wobei die Stirnflâchen der beiden 3.uBerenSchieberteile durch die KanS,le (36, 37) abwechselnd beaufschlagt bzw. auf Auspuff gesteuert werden, w5.hrend durch den mittleren Schieberteil (56) die mit den Arbeitsr5.umen vor den Kolben (32' bzw. 33') durch Leitungen (5g, 6o) verbundenen Anschlüsse (57, 58) im Wechsel mit dem zum Betâtigungskontakt (55) führenden AnschluB (6i) verbunden werden.
Connecting rod of the piston slide (51, 52) engaging projection (56) of the yoke (4i) is provided, through which the reversal is mechanically forced if the control piston (5i, 52) gets stuck. 4. Control according to claim i, characterized in that the switching is carried out by the reversing or working piston itself by the piston bodies (32 'or 32 ") acting like a slide or valve, the connections (53, 54) to the Actuating contact (55) can be assigned in such a way that they are alternately opened and closed by the pistons (32 ', 32 "). 5. Control according to claims 1 and 2, characterized in that a three-part piston valve (5 i, 52, 56) is located in the slide valve housing (5o) connected to the working space in front of the piston (32 'or 33') ), whereby the end faces of the two 3rd outer slide parts are alternately acted upon by the channels (36, 37) or controlled to the exhaust, while through the middle slide part (56) which with the working spaces in front of the piston ( 32 'or 33') by lines (5g, 6o) connected connections (57, 58) alternately with the connection (6i) leading to the actuation contact (55).
