Description
Stermotor mit 1 Ventil und mit paarweise gege@läufigen Kolben,die im Viertakt beaufschlagt werden,aber wie im Zweitakt arbeiten.Star engine with 1 valve and pistons running in opposite directions in pairs, the be applied in four-stroke, but work as in two-stroke.
Kreiskol@enmotoren erregten Aufschen,weil sie im Viertakt aufbereiteten aber im Zweitakt wirkten. Die Abgase wurden fast tollkonnen aus dem Brennraum verdrängt und dieser gut mit Frischluft gefüllt,wobei ein hohes pe erreicht wurde.Die Dreickkolben treiben dabei direkt die Welle.Bei luftgekühlten Kolben ist ein fast völliger Massenausgleich möglich,bei ölgekühlten zwar nicht,Die einzelnen Trommeln; sind bei hoher Leistung klein uid leicht und gestatten ein Hintereinanderschalte@.Der Nachteil dieser Motores sind die Kolbendichtung und die umständliche Kühlung derselben.Die-Dichtungen und der zu flache Brennraum lassen keime Dieselverdichtung zu.Höchste Zünddrücke Ton 12 atü und auffallender keiner Auspuff weisen schon auf die Nachteile von Dichtung und Brennraum hin.Rotary piston engines excited because they processed in four stroke but worked in two-stroke. The exhaust gases were pushed out of the combustion chamber almost perfectly and this well filled with fresh air, whereby a high pe was achieved. The triangular pistons drive the shaft directly. With air-cooled pistons there is an almost complete mass balance possible, although not with oil-cooled ones, The individual drums; are at high performance small and light and allow a series connection @. The disadvantage of this motor are the piston seal and the cumbersome cooling of the same. The seals and The combustion chamber, which is too shallow, allows for germs of diesel compression. Highest ignition pressures Ton 12 atü and noticeable no exhaust already point to the disadvantages of gasket and combustion chamber.
Trotzden ist der Brennstoffverbrauch bei ihn relativ günstig.Den# nach scheint der Kreiskolbenbetrieb auf die Welle in Bezug auf den Leistungsunsatz günstiger zu sein als der normale Kurbeltrieb.Diesa Nachteile - incl. Laufbahnverschleiß lassen den Kreiskolbenmotor noch als gewagtes Experiment erscheinen,zumal auch im Kompressorenbau seit Jahrzehnten der Kreiskolben den Tauchkolben nicht verdrängen konnte.Nevertheless, the fuel consumption is relatively cheap with him. after the rotary piston operation seems to be on the shaft in terms of the power increase to be cheaper than the normal crank drive. These disadvantages - including raceway wear make the rotary piston engine appear to be a daring experiment, especially in the Compressor construction for decades the rotary piston has not displaced the plunger could.
Der folgend beschriebene Anmeldegegenstand will die Vorteile des Kreiskolbenmotors übernehnen,jedoch nur bewährte Maschinenelemente benutzen,wobei auch ein Dieselbetrieb möglich sein würde.The subject of the application described below seeks the advantages of the rotary piston engine Overstretch, but only use proven machine elements, including a diesel operation would be possible.
Die Kolbenzapfen 1 tragen Rollen2,die den Nocken 3 und die Welle4 treiben. Auf ien Kolbenzapfen 1 sitzen noch Zahnstangen 5,die alle auf das lose auf der Welle 4 sitzende Zahnrad 6 so eingreifen,daß immer 2 gegenübersitzende Kolben gegenläufig arbeiten und dadurch massenmäßig ausgeglichen sind.Bei 4 Zylindern können diese außermittig stehen, um schon beim höchsten Zünddruck ein Drehmoment auszuü ben. Bei nur 2 Zylindern müssen beide in einer Achse liegen, well sonst ein freies Kippmoment entsteht.The piston pin 1 carry rollers2, which the cam 3 and the shaft4 to drive. On the piston pin 1 there are still racks 5, all of which are loose Gear 6 seated on the shaft 4 engage so that there are always 2 opposing pistons work in opposite directions and are therefore balanced in terms of mass. With 4 cylinders, these are off-center in order to exert a torque even at the highest ignition pressure ben. With only 2 cylinders, both must be in one axis, otherwise a free one Tilting moment arises.
In jedem Zylinderkopf sitzt 1 großes Ve ntil 7, sowohl für Ausals auch Einlaß, Das auch bei geringem Ventilhub genügend Querschnitt freigibt- Mit dci Ventil verbunden ist ein Rohrschieber 8, der bei beginnend ei Ventilhub H1, Fig 4, den Auslaßkanal A öffnet und nachher bei größerem Hub M2 den Einlaßkanal E. Der Roirschieber 8 kann nach Fig 3 (linke Hälfte) mit Einlaßkanal E nahe dem Ventilsitz ausgeführt werden oder Fig 3 (rechte Hälfte) mit einer Ringt####wand 9 und dem Auslaßkanal A nahe dem Ventilsitz.Dadurch soll ein Mischen von Abgas und Frischluft verhindert werden.Das öffnende Ventil 7 drückt außerdem bei Ende Auspuff so im die Kolbenmulde 10,Fig 3, daß dadurch die Abgase aus dem Brennraum verdrängt werden.Der Brennraum läßt eine hohe Verdichtung zu.Ein-und Auslaßringkanäle E und A sind spiralförmig un den Rohrschieber 8 angeordnet Fig 5,damit sowohl Abgase und nachher Frischluft bzw. Gemisch inner in gleicher Drehrichtung rotieren und neben bekannten Vorteilen sich beim Entleeren und Auffüllen gegenseitig unterstützen.Den Steuernokken 11 mit den kleinen Hub H1 für den Auslaß und nachher mit größeren Hub H2 für den Einlaß zeigt Fig 4. Fig 1 zeigt Zylinder I bei Beginn Dehnen,Zyl II bei Beginn Auspuff,Zyl III bei Beginn Saugen und Zyl IV bei Beginn Verdichten.Die 4 Takte verteilen sich entgegen der Drehrichtung,die Zündungen dagegen gehen mit der Drehrichtung,also I,IV,III,II. Vereinigt man die gemeinsame Saugleitung aller 4 Zylinder zu einem ringförmigen Rohr 12 Pig 6,herrscht in dieser Leitung 12 ein kontinuierlicher Gleichstrom im Gegensatz zu Kurbelwellenmotoren,wo störende Schwingungen auftreten.In each cylinder head there is 1 large valve 7, both for exhaust and also inlet, which releases enough cross-section even with a small valve lift Connected to the valve is a pipe slide 8, which starts at valve stroke H1, 4, the exhaust port A opens and afterwards the intake port with a larger stroke M2 E. The Roir slide 8 can be close to Fig. 3 (left half) with inlet port E to the Valve seat are executed or Fig 3 (right half) with a ring #### wall 9 and the outlet channel A near the valve seat. This is intended to allow the exhaust gas and The opening valve 7 also presses at the end of the exhaust so in the piston recess 10, Fig. 3, that it displaces the exhaust gases from the combustion chamber The combustion chamber allows high compression. Inlet and outlet ring channels E and A are arranged in a spiral un the slide valve 8 Fig 5, so that both exhaust gases and then rotate fresh air or mixture inside in the same direction of rotation and next to known advantages support each other when emptying and refilling Control cokes 11 with the small stroke H1 for the outlet and afterwards with a larger stroke H2 for the inlet is shown in FIG. 4. FIG. 1 shows cylinder I at the start of stretching, cylinder II at Start of exhaust, Cyl III at the start of suction and Cyl IV at the start of compression Clocks are distributed against the direction of rotation, the ignitions, on the other hand, go with the Direction of rotation, i.e. I, IV, III, II. If the common suction line of all 4 Cylinder to an annular tube 12 Pig 6, there is a continuous in this line 12 Direct current in contrast to crankshaft motors, where disturbing vibrations occur.
Kerzen-oder Einspritzventilstellung richten sich nach der Zylindergröße.In Fig 1 u.2 ist die Kühlung zit Luft angedeutet.Jede andere ist möglich. Das Schwungrad kann klein sein.Ein Massenausgleich ist nicht nötig.Zündverteiler und Einspritzpumpe haben die Drehzahl der Welle 4.Bei kleineren Motoren nit kleinem Ventilhub ersetzt eine dicke Welle 15 die Schwinghebel.The spark plug or injection valve position depends on the cylinder size The cooling with air is indicated in Fig. 1 and 2. Any other is possible. The flywheel can be small, mass balancing is not necessary, ignition distributor and injection pump have replaced the speed of shaft 4 in smaller motors with a small valve lift a thick shaft 15 the rocker arm.
Es lassen sich mehrere solcher Sterne hintereimandersetzen.Several such stars can be placed one behind the other.
Der Flächendruck der Rolle 2 auf den Nocken 3 in Zündpunkt ist klei-@er als die Walzenpressung auf das erste nachgeordnete Getriebzahnrad.The surface pressure of roller 2 on cam 3 at the ignition point is lower than the roller pressure on the first downstream gear wheel.
Ein Vorteil dieses Sternmotors liegt noch darin,daß die Massenkräfte aller Kolben etc in den Totlagen über die Zahnstangen 5 verein#gnig# die Verdichter arbeit 1 Zylinders unterstützen-ohne im das Schwungrad und wieder zurückzufließen und dadurch dem Leistungsumsatz bein Kreiskolben gleichen.Another advantage of this radial engine is that the inertia forces all pistons etc in the dead positions via the gear racks 5 unite the compressors work 1 cylinder support - without flowing in the flywheel and back again and thus equal to the power turnover in rotary pistons.
