Description
Druckluftmotor. Betreibt man Druckluftmotoren nach Art der Gleichstromdampfmaschinen mit vom Kolben gesteuertem Auslaß, so ergibt sich beine Kolbenrückgang eine unerwünscht hohe Kompressionsendspannung. Auch bei Gleichstroindampfmaschinen tritt dieser Übelstand dann auf, wenn das @"akuum nachläßt, oder die :Maschine mit Auspuff in die Atmosphäre arbeitet, und man hat zur Abhilfe schon vorgeschlagen, Hilfsauslaßorgane, die zusammen finit der Einlaßsteuerung betätigt werden, zu verwenden.Air motor. If air motors are operated in the manner of direct current steam machines with the outlet controlled by the piston, there is an undesirable piston retraction high compression end tension. This drawback also occurs with direct-flow steam engines then on when the @ "akuum wears off, or the: machine with exhaust into the atmosphere works, and it has already been suggested to remedy this, auxiliary outlet organs that work together finite of the inlet control to be operated.
Erfindungsgemäß soll bei Druckluftinotoren ein gesteuerter Hilfsauslaß dadurch geschaffen werden, claß der .das Einlaßventil bewegende Stößel als Hilfsauslaßorgan ausgebildet ist.According to the invention, a controlled auxiliary outlet is intended for compressed air motors thereby created, the .das inlet valve moving plunger as an auxiliary outlet member is trained.
Ein Ausführungsbeispiel ist in der Zeichnung dargestellt.An exemplary embodiment is shown in the drawing.
Der einfach wirkende Motor erhält als Einlaßorgan ein Ventil a, während der Austritt durch Schlitze h erfolgt. Das Ventil wird unmittelbar durch einen Stößel c von der unrunden Scheike d betätigt. Das Ventil a wird durch die Fader e, der Stößel durch die Feder f zurückbewegt. Der Stößel c dient 11111i gleichzeitig als Hilfsauslaßorgan, indem auf dein ol:eren Teil des Stößels Längsnuten g angebracht «-erden, welche während des Rücklaufes des Kolbens das Zvlinderinnere mit dein Auslaßraum h verbinden.The single-acting motor is provided with a valve a as the inlet element, while the outlet takes place through slits h. The valve is actuated directly by a plunger c from the non-circular Scheike d . The valve a is moved back by the fader e, the plunger by the spring f. The plunger c serves at the same time as an auxiliary outlet member, in that longitudinal grooves g are made on the oil part of the plunger and connect the interior of the cylinder with the outlet space h during the return of the piston.
Die unrunde Scheibe d ist so ausgebildet, ilaß während des Rücklaufes des Kolbens der Stößel sich so weit nach unten verschiebt, daß die Nuten g einerseits die Kante i. des Ringraumes h überlaufen, anderseits mit dem Zvlinderinnern in Verbindung stehen und so die gewünschte Auslaßverbindung herstellen.The non-circular disk d is designed so that it can be used during the return movement of the piston of the plunger moves so far down that the grooves g on the one hand the edge i. of the annular space h overflow, on the other hand with the cylinder interior in connection and thus establish the desired outlet connection.
Der Gegenstand der Erfindung bleibt derselbe, wenn anstatt der einfachen Nuten Bohrungen in dem Stößel vorgesehen werden, oder wenn diese Nuten oder Überstromkanäle in einer besonders auf den Stößel aufgesetzten Büchse liegen. Auf diese Weise ist ein zu frühes Auftreten hoher Kompressionen vermieden, und es wird ein völligeres Diagratnni erreicht.The object of the invention remains the same if instead of the simple one Grooves bores are provided in the plunger, or if these grooves or overflow channels lie in a sleeve specially placed on the plunger. That way is avoiding high compressions too early and becoming more complete Diagratnni achieved.
