Description

Umsteuerung für Drehkolbenmaschinen mit sichelförmigem Arbeitsraum und in der Kolbentrommel radial verschiebbaren Kolben, unter völliger Vermeidung der Kompression des Treibmittels. Wenn man die Umlaüfimaschii,nen mit exzentrisch gelagerter Kolbentrommel und diarin radial verschieblichen Kolben für wecn- sielnde D;relhnichttmg nwsbädet, so empfiehlt es sich, auf jeder Seite gesondevte E'inlaß- und Auslaßkanälle zu verwenden, um Ein1aß und Auslaß, :den an sie ggiestellten Bedingungen ent- sprechend, rausbilden zu können. Hierbei be- reitet :nun die idoppelseitige Anlbrdngurng von Eimaß ;und Au laß insofern Slclhwiierigkeitan, als bekanntlich der Awsl@aß sich über d;engan- zen Bogen .erstrecken muß, auf :düni :diie Ar- beitsräulme sich verkleinern, während der Einlaß insofern an der gleichien Stelle erfol- gen muß, als er .im Anfang der Vergrößerung der Arbeit,sräume einsetzen muß. Bei dran nun aus praktischen. Gründen,unvermeiidlichen Nebeneinander von Ei@nlaß und Auslaß tritt auf dien Bogen zwischen. Auslaß und dem lauf dieser Seite abgeschlossenen Ei.nlaß eine Ver- dic'htung ein, diie einen, unwil lkominenen Rück@d,ruck für idie Maschine bedeutet. Man 'hat ibereits (vgl. franz. Patentschrift 333o83) eine Einrichtung getroffen, bei der dieses Auftreten eines Rück@d,riwckos dadurch vermieden w.i:rd.,-,diaß,doch wieder dem auf dem Auslaß.bogen eingeschlossenen Dru*,mittel ein Ein.laßkanal durch den Umsteuerschleber eröffnet wird, wodurch tatsächlich ;die Ver- 4ichbung bei der Bewegung der Kolbenflizgel auf ,düesiem Bogen vermiedene, wird.. Mit der Erfindung wird die gleiche Aufgabe in elegan- terer 'Weise gelöst, insofern al:s zunächst über -dem ganzen Arbeitsbogen, der der Verkleine- rung der Arbeitsräume entspricht,eine Aus- 1aßmögl;ichkei:t geschaffen wird, während der Eimaß .innerhalb der gleichen Strecke durch besondere, dien Aus.laß durchsetzende Röhr- chen gebildet wird. Gerade .infolge dieses Durchsetzerns des Auslasses durch dien Ein- laß sind. in .einifachster Weise für .beide die erforderlichen Bedingungen erfüllt, ohne saß damit rückwärts eine gegenseifige Störung verknüpft wäre. Dazu oanmt noch, idaß man diese Einlaß,röhrdhen durch geeignete düsen- förmige Ausbildung einerseits und ihre ,an- nähernd tangentlale Anordnung @anderseits auch noch -so ausbilden kann, d:aß nebien,dien rein statiischen Druck dies Betri.ebsmdttels auch .noch seine Strömungsenergie etwas aus- genutzt wir.d. Inder Zeichnung ist eine Ausführungsform -des Erfindunigsgegenstandes kn A1yb. i und 2 im Qu@ersdmitt und Längsschnitt wiedergege- ben, und zwar -in Anwündung auf eine @um- steuerbare Maschine, wie solche zum Antrieb von Förderhaspeln u. rigl. henutzt werden kann. In dien Gehäuse i o, dias durch Deckel i i abgeschlossen ,i,st, dreht sich mnit der zentri- schen, .in Kugellagern 12 laufenden Achse 13 die Kolbentrommel 14, in der de Kolben 15 in radialen Schlitzen verschiebbar sind. Zw-i- sclhen dem Gehäuse io und der Kolbentrom- mel 14 :ist -das Einsatzstück 16 geschaltet, das innen und außen nach verschiedenen, um .das Maß der Exzentrizität e versetzten Mittel- punkten albgedreht ist. Damit liegt,das Ein- satzstück 16 rrnit seinem unteren Teil dicht an dem Innenumfang des Gehäuses io an, wäh- rendes s'ic'h oben .mit deal Alns.atz 17 dagegen anlegt. Die sich @derngeinäß zu beiden Seiten des Einsatzstückes 17 ergehenden sichelförmigen Räume 25, 25' dlienen als Aus- und Einlaß- sammelräume, indem sie einerseits durch Kanäle 18, 18' zu einem Sdhieberspiegel ge- führt werdie@n, auf @die,m der Muschelschieber 19 mit Hilfe des :Gestänges 2o verstellt wer- den kann, und indem sie anderseits durch Kanäle 23, 23' des Einsatzstückes 16 m,it dem Arbeitsramm verbunden sind. Durch die Muschel kann j eweilig idie Verbindung von, 18 oder i8' m:it dem Kanal 21 herbeigeführt wer- den., ,der zum Auspuff 22 führt. Die Kanäle 23, 23' .sind lannähernd tangential gestellt, so d,aß das :ausströmende Treibmittel möglichst ohne Riolhtungsumk ehr aus diem Arbeitsraum in d;ie Kanäle i8 bzw. 18' belangen kann. Der Eimaß des Treibmittels erfolgt unter Ver- mittlung der Kanäle 23, 23' @d;urch eine Anzahl von Röhrchen 24, 2.a.', ;die vorn Schieberspie- äel aus die sichelförmigen @a@mm@elräume durchsetzen Bund dicht ,i,n das Einsatzstück 16 eingesetzt sind. Durch .diese Einrichtung wird erreicht, daß bei völliger Vermeiidung der Ko@mpres;sion der Einlaß des Treibmittels in alle Arbeitszellen der Masclh@i,nie erfolgt ohne Benutzung der gleichen Kanäle sowohl für Ein- als auch Aus- laß. Letzteres gestattet die Verwendung :der Röhrchen 24, 2d.' zur Regelung (der Leistung, wenn in @die Röhrchen Abschlußorgane einge- baut werden, so saß die Röhrchen in beke- biger Anzahl für d'en Einlaß verwendet wer- den können. Reversal for rotary piston machines with a sickle-shaped working chamber and pistons that can be moved radially in the piston drum, completely avoiding the compression of the propellant. If you use the Umlaüfimaschii eccentrically mounted piston drum and radially displaceable piston for reversible sielnde D; relhnichttmg nwsbädet, it recommends separate inlet and outlet ports on each side To use outlet ducts to inlet and Outlet,: the conditions set for you speaking to be able to train. Here, rides: now the double-sided attachment of Measure; and let there be difficulty in as is well known the Awsl @ ate himself about the narrow zen arch. must stretch, on: thin: the ar- Beitsräulme decrease during the Admission takes place at the same point when he started the enlargement the work, spaces must use. With it now for practical reasons. Reasons, inevitable The inlet and outlet occur side by side on the arc between. Outlet and the barrel on this page, leave a Thought one, the one unwillingly Rück @ d, jerk for i means the machine. One already has (see French patent specification 333o83) established a facility in which this occurrence of a Rück @ d, riwckos thereby is avoided: rd., -, diaß, but again the one on the Outlet bend enclosed pressure, medium an inlet channel through the reversing valve is opened, whereby actually; the Exercise in the movement of the piston wing on, avoiding the bow, will .. With the Invention accomplishes the same task in elegant solved in a different way , insofar as: s first about -the whole worksheet, the one of the small ones- of the workspaces, an 1aßmögl; ichkei: t is created during the Measured within the same distance special tube penetrating the exterior chen is formed. Just because of this Enforcement of the outlet through the inlet let are. in the easiest way for both of them Required conditions met without sat thus backwards a counter-soap disturbance would be linked. In addition to that, one also oanmt pipe this inlet through suitable nozzle shaped training on the one hand and its, on the other approximately tangential arrangement @ on the other side also -so can train, d: ate nebien, dien purely static pressure of this operating medium also. is being used. In the drawing is an embodiment -the subject of the invention kn A1yb. i and 2 reproduced in the Qu @ ersdmitt and longitudinal section practice, namely -in application to an @ um- controllable machine, such as those for propulsion of conveyor reels and rigl. be used can. In the housing io, dias through cover ii completed, i, st, rotates with the centric between,. in ball bearings 12 running axis 13 the piston drum 14 in which the piston 15 are displaceable in radial slots. Zw-i- the housing and the piston mel 14: the insert 16 is switched, the inside and outside according to different to .that Degree of eccentricity e offset central score is rotated. So lies the one Clause 16 with its lower part close together the inner circumference of the housing, while rendes s'ic'h above .with deal Alns.atz 17 against it applies. The @ derngeinäß on both sides of the Insert 17 going sickle-shaped Rooms 25, 25 'serve as outlet and inlet collection rooms by putting one hand through Channels 18, 18 'to a swash mirror leads werdie @ n, on @ die, m the mussel slide 19 can be adjusted with the help of the rod 2o that can, and by doing it on the other hand Channels 23, 23 'of the insert 16 with the Working rams are connected. Through the Mussel can in each case i the connection of, 18 or i8 'with: it can be brought about by channel 21 the., which leads to the exhaust 22. The channels 23, 23 '. Are approximately tangential, see above d, ate the: leaking propellant if possible without reversing the direction from the work area in the channels i8 or 18 '.
