Description

Preßlcftmaschine mit Drehkolben. Die Erfindung betrifft eine Preßluftinas.chine mit Radialschieberdrehkolben und Winkelansätzen an den Schiebern und bezweckt, die Kolbenreibung zu vermindern. Dies wird nach der Erfindung dadurch erreicht, daß auf dem Rückweg des Kolbens, die sich verdichtende Luft durch enge, in einen gemeinsamen Ausströmungskanal mündende Löcher austritt und daher teilweise gedrosselt wird. Infolgedessen entstehen auch beim Rückgang des Kolbens zwischen :den einzelnen Zy linderräuinen Druckunterschiede, die zusammen mit bekannten Winkelansätzen an den Schiebern deren Anliegedruck schwächen. Dadurch wird die Reibung zwischen den Schiebern und der Zylinderbüchse verringert. Die Maschine nach der Erfindung eignet sich auch für andere Bettrniebsmittel, wie z. B. Dampf.Pressing machine with rotary piston. The invention relates to a Preßluftinas.chine with radial slide rotary lobes and angle attachments on the slides and aims that To reduce piston friction. This is achieved according to the invention in that on the way back of the piston, the compressing air through tight, into a common Exiting outflow channel opening holes and is therefore partially throttled. As a result, when the piston retracts between: the individual Zy linderräuinen pressure differences, which together with known angular approaches to the Sliders weaken their contact pressure. This will reduce the friction between the slides and the cylinder liner is reduced. The machine according to the invention is also suitable for other bed libations, such as B. Steam.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung in einem. Schnitt veranschaulicht.In the drawing, an embodiment of the invention is in one. Section illustrates.

Der Drehkolben a ist in bekannter Weise mit Schlitzen b und Schiebern c versehen. Durch Schlitze d, eine daMnter liegende Kammer f und einen weiten Auspuffstutzen g gelangt die wirksam gewesene Preßluft aus den Zylinderäumen e ins Freie. Jeder Schieber c bat in bekannter Weise einen Winkelansatz h, dessen längerer Schenkel quer zum Schieber steht und dessen kurzer, radial gerichteter Schenkel an der Innenwand des Zylinders entlangschleift. Die Winkelansätze h regeln in bekannter Weise während jeder ersten halben Umdrehung,des Kolbens wegen der zwischen den einzelnen Zylinderräumen e herrschenden Druckunterschiede den Anliegedruck der Schieber c. Die Schieberansätze können auch andere Formen haben.The rotary piston a is in a known manner with slots b and slides c provided. Through slits d, a chamber f underneath, and a wide exhaust pipe The compressed air that has been effective reaches the outside from the cylinder spaces e. Everyone Slide c asked in a known way an angle approach h, the longer leg stands transversely to the slide and its short, radially directed leg on the inner wall dragging along the cylinder. The angle approaches h regulate in a known manner during every first half turn of the piston because of the space between the individual cylinder chambers e prevailing pressure differences the contact pressure of the slide c. The slider approaches can also have other forms.

Die untere Hälfte der Zylinderbüchse hat enge Löcher i, die in einen gemeinsamen Kanal k münden. Bei jeder zweiten halben Uhrdrehung des Kolbens a wird daher die in den Zylinderräumen e sich verdichtende Luft teilweise gedrosselt, derart, daß in diesen auch beim Rückweg des Kolbens Druckunterschiede entstehen. Die verdichtete Luft sucht durch Druck auf die äußere Seite des quer stehenden Schenkels des, Winkelansatzes h die Schieber c nach. innen zu drücken. Wegen dieses Gegendrucks werden die Schieber durch die Umdrehungen des Kolbens a weniger stark herausgeschleudert, so daß die Reibung zwischen den Schiebern und der Zylinderbüchse herabgesetzt wird. Die engen Löcher i müssen natürlich so gro3 sein, daß in den Zylinderräumen keine Spannung auftritt, die die Leistung der Preßluftmaschine nennenswert vermindert.The lower half of the cylinder liner has narrow holes i that go into a common channel k open. Every other half a clock turn of the piston a becomes therefore the air compressing in the cylinder chambers e is partially throttled, in such a way that that pressure differences also arise in these on the return path of the piston. The condensed Air seeks through pressure on the outer side of the transverse leg of the angled attachment h the slide c after. to push inside. Because of this back pressure, the valves thrown out less strongly by the revolutions of the piston a, so that the Friction between the slides and the cylinder liner is reduced. The tight ones Holes i must of course be so large that there is no tension in the cylinder spaces occurs, which significantly reduces the performance of the compressed air machine.
