Description
Einrichtung zum Verändern des Hubes eines Flüssigkeits-Schubkolbenmotors Die Erfindung betrifft eine Einrichtung zum Verändern des Hubes eines Flüssigkeits-Schubkolbenmotors durch Verändern der Länge des wechselseitig beaufschlagbaren Arbeitskolbens.Device for changing the stroke of a liquid piston engine The invention relates to a device for changing the stroke of a liquid reciprocating piston engine by changing the length of the reciprocating working piston.
Bekannte Motoren dieser Art haben einen Doppelkolben, der von einem Vorholkolben größerer wirksamer Druckfläche und einem Rückholkolben kleinerer wirksamer Druckfläche gebildet wird. In den Rückholkolben ist eine Gewindebuchse eingeschraubt, die mittels eines Steckschlüssels von außen verschraubt werden kann. Für den Vorholkolben und den Rückholkolben bzw. dessen Gewindebuchse sind an den Zylinderenden feste Anschläge vorgesehen, die den Hub des Doppelkolbens begrenzen. Ist die Gewindebuchse vollständig in den Rückholkolben eingeschraubt, so hat der Doppelkolben seinen größten Hub. Durch Herausschrauben der Gewindebuchse läßt sich der Hub bis auf Null verkürzen. Auf diese Weise wird praktisch jede Verkürzung des Hubes zwangläufig von einer entsprechenden Verlagerung des Arbeitsweges des Abtriebsgliedes des Doppelkolbens in Richtung auf den vorkolbenseitigen Anschlag zu begleitet. In bestimmten Fällen kann aber gerade eine Verlagerung des Arbeitsweges des Abtriebsgliedes in entgegengesetzter Richtung erwünscht sein. Diese ist mit der beschriebenen Einrichtung nicht durchführbar. Vor allen Dingen gestattet es diese Einrichtung nicht, den Hub überhaupt ohne Verlagerung des Arbeitsweges des Abtriebsgliedes zu verändern, so daß die Mitte des Abtriebsgliedweges zum Festpunkt wird. Hierauf kommt es z. B. an, wenn ein solcher Motor zum Antrieb der Fadenführer von Kreuzspulmaschinen benutzt wird, auf der Spulen mit unterschiedlicher Länge gebildet werden sollen. Der Fadenführerweg ist in diesem Falle von der Spindellängsmitte aus symmetrisch auf beiden Seiten zu verlängern oder zu verkürzen, wenn eine Änderung der Spulenlänge beabsichtigt ist.Well-known engines of this type have a double piston that is driven by a A return piston with a larger effective pressure area and a return piston with a smaller effective pressure area Printing area is formed. A threaded bushing is screwed into the return piston, which can be screwed on from the outside using a socket wrench. For the advance piston and the return piston or its threaded bushing are fixed to the cylinder ends Stops are provided that limit the stroke of the double piston. Is the threaded bushing fully screwed into the return piston, the double piston has its largest Hub. The stroke can be shortened to zero by unscrewing the threaded bushing. In this way, practically every shortening of the stroke is inevitably accompanied by a corresponding one Shifting the working path of the output member of the double piston in the direction of to accompany the stop on the front piston side. In certain cases it can a shift in the working path of the output member in the opposite direction be desirable. This cannot be carried out with the device described. Most importantly, this facility does not allow the hub to be operated without relocating at all to change the working path of the output member, so that the center of the output member path becomes a fixed point. It comes to z. B. on when such a motor to drive the thread guide of cross-winding machines is used on the bobbins with different Length should be formed. In this case, the thread guide path is from the longitudinal center of the spindle to lengthen or shorten out symmetrically on either side when making a change the coil length is intended.
Einen Flüssigkeits-Schubkolbenmotor zu schaffen, der alle diese Forderungen erfüllt, ist Aufgabe der Erfindung. Diese besteht darin, daß der Arbeitskolben aus zwei gegeneinander verstellbaren Einzelkolben besteht.To create a liquid piston engine that meets all of these requirements fulfilled, is the object of the invention. This consists in that the working piston is made of consists of two mutually adjustable single pistons.
Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung.The drawing shows an embodiment of the invention.
In dem Zylindergehäuse 1 läuft der wechselseitig beaufschlagbare Arbeitskolben, der zum Verändern seiner Länge aus zwei gegeneinander verstellbaren Einzelkolben 2 und 3 besteht. Die Einzelkolben 2 und 3 befinden sich an den inneren Enden von zwei Hülsen, die an ihren äußeren Enden je einen mutterartigen Bund 4 bzw. 5 mit Innengewinde aufweisen. Mit diesen Innengewinden sind die Hülsen auf eine durchgehende Stange 6, die an ihren Enden je ein Außengewinde 7 bzw. 8 hat, aufgeschraubt. Durch Verdrehen der Hülsen lassen sich die Kolben 2 und 3 axial auf der durchgehenden Stange 6 verschieben. Gegenmuttern 9 und 10 dienen dazu, die axial eingestellten Einzelkolben 2 und 3 an der Stange 6 festzulegen. In geläufiger Weise kann die Stange 6 gleich als unmittelbares Abtriebsglied, beispielsweise als Fadenführer einer Kreuzspuhnaschine, dienen.The working piston, which can be acted upon alternately and which consists of two mutually adjustable individual pistons 2 and 3 to change its length, runs in the cylinder housing 1. The individual pistons 2 and 3 are located at the inner ends of two sleeves which each have a nut-like collar 4 and 5 with an internal thread at their outer ends. With these internal threads, the sleeves are screwed onto a continuous rod 6, each of which has an external thread 7 or 8 at its ends. The pistons 2 and 3 can be moved axially on the continuous rod 6 by rotating the sleeves. Lock nuts 9 and 10 are used to fix the axially adjusted individual pistons 2 and 3 on the rod 6. In a common way, the rod 6 can serve as a direct output member, for example as a thread guide of a cross-winding machine.
Der Begrenzung der Bewegung des aus den beiden Einzelkolben 2 und 3 bestehenden Arbeitskolbens dienen in geläufiger Weise die Deckel des Zylindergehäuses 1, wobei die Hublänge des Arbeitskolbens vom gegenseitigen Abstand der Einzelkolben 2 und 3 bestimmt wird. Letztere werden durch die Druckflüssigkeit wechselweise beaufschlagt.The limitation of the movement of the two single pistons 2 and 3 existing working pistons are used in a common way, the cover of the cylinder housing 1, where the stroke length of the working piston depends on the mutual distance between the individual pistons 2 and 3 is determined. The latter are alternately acted upon by the hydraulic fluid.
