Abstract

The eccentric shaft slide-piece has an equalising ring (1b) on the rotaty cam (1a) and which is rotated at the same speed in a contrary direction to produce a constant to and fro movement of the parts mounted on the outside of the equalising ring (1b). The eccentric shaft and the equalising ring have spars (2e & d) which equalise the centrifugal force of the to and fro movements and cause them not to vibrate by weighting the corresponding parts. ADVANTAGE - The eccentric shaft slide-piece with a rigid piston rod, instead of a crank shaft and connecting-rod, cause quiet running, need only gear-oil for lubricating the parts and have separate oil lubrication not needing to be replenished.

Description

Es ist bekannt, eine Drehbewegung durch eine Kurbel oder eine Exzenterwelle mittels einer Pleuelstange über ein Pleuellager und eine seitliche Führung in eine gradlinige Bewegung umzusetzen (z. B. Otto-Motor). Ebenso ist dies bei in einer Führung laufenden Schiebern, die durch drehende Nocken verschoben werden (Ventilsteuerung).It is known to have a rotary movement by means of a crank or an eccentric shaft by means of a connecting rod via a connecting rod bearing and a lateral guide in implement a straight-line movement (e.g. Otto engine). This is also the case with in a guiding slide that is moved by rotating cams (Valve control).

Neben dem unruhigen Lauf benötigt die Kurbelwelle einen relativ großen Raum für die Kreisbewegung. Die pendelnde Kolbenstange führt neben ihrem Schwung zu einem seitlichen Andruck des Kolbens bzw. Schiebers. Beim Verbrennungsmotor ist der Kurbelwellenraum zum Zylinderraum offen, wodurch das Schmiermittel mit Verbrennungsrückständen vermischt wird.In addition to the restless running, the crankshaft requires a relatively large space for circular motion. The oscillating piston rod leads alongside its momentum a lateral pressure of the piston or slide. With the internal combustion engine the crankshaft space is open to the cylinder space, causing the lubricant is mixed with combustion residues.

Der in Anspruch 1 angegebenen Erfindung liegt das Problem zugrunde,The invention specified in claim 1 is based on the problem

1. Piston or slide without lateral force effect with reduction vibrating parts from a rotational movement in a straight line to move or vice versa (1);
2. the piston by rotating the drive shaft as an advantageous sliding valve to be used with four-stroke engines (18);
3. to enable corresponding piston capacities by more piston functions on a bearing, intensify the way of working, compress it in several stages or to relax (24, 27);
4. over multi-function pistons (22, 34, 35, 38) opposite work phases, such as. B. Compression and relaxation to interact directly to Reduce friction losses;
5. More environmentally friendly energy use by eliminating the lubricant in the fuel (23), higher compression and further relaxation (35, 38).

Die durch die Erfindung erzielten Vorteile bestehen darin, daß anstelle der Kurbelwelle und Pleuelstange bei dem Exzenterwellenschieber mit starrer Kolbenstange eine hohe Laufruhe durch exakte Auswuchtung möglich ist. Der seitliche Andruck durch die Funktion der Pleuelstange entfällt. Der erforderliche Raum bzw. das Gehäuse ist kleiner. Die beweglichen Teile können mit Getriebeöl geschmiert werden. Für den Kolben erfolgt separate Schmierung, wodurch der Ölverbrauch bestehen bleibt, aber kein Ölwechsel mehr notwendig wird.The advantages achieved by the invention are that instead of Crankshaft and connecting rod on the eccentric shaft slide with rigid piston rod smooth running is possible due to exact balancing. The side Pressure due to the function of the connecting rod is eliminated. The required Space or the housing is smaller. The moving parts can with gear oil be lubricated. Separate lubrication takes place for the piston, whereby the oil consumption remains, but no more oil change necessary becomes.

Diese Erfindung ermöglicht es, einen Zweitaktmotor ohne Schmiermittel im Treibstoff zu betreiben. Hierbei wird im Zylinderraum unterhalb des Kolbens durch eine feste Platte zwischen Zylinderwand und Kolbenstange der Zylinderraum abgeschlossen (23). Die Schmierung des Kolbens erfolgt durch einen Ölkanal in der Zylinderwand oder am Kolben zwischen Abdichtungsringen (16, 21).This invention enables a two-stroke engine without lubricant in the To operate fuel. Here, in the cylinder space below the piston the cylinder space through a solid plate between the cylinder wall and piston rod completed (23). The piston is lubricated through an oil channel in the cylinder wall or on the piston between sealing rings (16, 21).

Die in Anspruch 2 angegebene Ausgestaltung ermöglicht eine genaue Auswuchtung, da die Gewichtsstollen an Exzenter und Ausgleichsring (2) einander entgegenlaufen und gleichzeitig den Schwung des Kolbens ausgleichen.The embodiment specified in claim 2 enables precise balancing, since the weight lugs on the eccentric and the compensating ring (2) run in opposite directions and at the same time balance the swing of the piston.

Die in Anspruch 3 angegebene Versetzung auf 180° ergibt die Möglichkeit, zwei entgegenlaufende Kolben (3, 22, 25, 26, 27) auf einer Zylinderachse zu bewegen, wodurch Flieh und Schwung ausgeglichen werden.The offset to 180 ° specified in claim 3 gives the possibility of two to move opposing pistons (3, 22, 25, 26, 27) on a cylinder axis, which balances fleeing and momentum.

Ein besonderer Vorteil dieser Erfindung ist nach Anspruch 4 die Führung der Kolbenstange in Richtung der Zylinderachse bzw. der gewünschten Hubrichtung. Dies erfolgt durch die Lagerung am Ausgleichsring, der infolge seiner entgegengesetzten Drehung zum Exzenter die Kolbenstange auf einer Linie führt. Exzenter und Ausgleichsring drehen sich mit gleicher Geschwindigkeit.A particular advantage of this invention is the leadership of the claim Piston rod in the direction of the cylinder axis or the desired stroke direction. This is done by mounting on the compensation ring, which is due to its opposite Rotation to the eccentric leads the piston rod in a line. eccentric and compensation ring rotate at the same speed.

Die Ausgestaltung nach Anspruch 5 ermöglicht es, mehrere Ausgleichsringe auf einer Achse zu drehen (6, 8, 14). Die Steuerwelle hierfür liegt im Drehpunkt des Exzenters bzw. Exzenterwelle. Die auf der Steuerwelle aufgesetzten Zahnräder drehen die Ausgleichsringe mit.The embodiment according to claim 5 makes it possible to have several compensation rings axis (6, 8, 14). The control shaft for this lies in the fulcrum of the Eccentric or eccentric shaft. The gears on the control shaft rotate the compensation rings.

Die Ausgestaltung nach Anspruch 6 ist durch die Verwendung von wenig Teilen eine robuste Ausführung, bei der der Ausgleichsring mit einem Zahnrad am Gehäuse (Zahnkranz) abrollt (30). Der Durchmesser des Zahnkranzes ist doppelt so groß wie der des Zahnrades. Dadurch entsteht die entsprechende Gegenbewegung des Ausgleichsringes zum Exzenter, welcher durch die Verringerung des Durchmessers als Kurbel ausgebildet ist. Infolge dieser Verringerung ist der Ausgleichsring in seiner Wirkung verstärkt (Drehpunkt dezentralisiert).The embodiment according to claim 6 is a through the use of few parts robust design, in which the compensating ring with a gear on the housing (ring gear) rolls (30). The diameter of the ring gear is twice as large as that of the gear. This creates the corresponding counter movement of the compensating ring to the eccentric, which acts as a crank by reducing the diameter is trained. As a result of this reduction, the compensating ring is effective reinforced (pivot point decentralized).

Die Ausgestaltung nach Anspruch 7 und 8 bietet die Möglichkeit, den Hubkolben um die Zylinderachse zu drehen (10, 11, 12, 13, 14) und dadurch den Kolben als Ventilschieber auch für Viertaktmotoren, Kompressoren oder Pumpen zu benutzen.The embodiment according to claim 7 and 8 offers the possibility of the reciprocating piston to rotate the cylinder axis (10, 11, 12, 13, 14) and thereby the piston as Valve spool can also be used for four-stroke engines, compressors or pumps.

Die Ausgestaltung nach Anspruch 9 bewirkt, daß der Kolben, Schlitze und Öffnungen, je nach Formgebung, an den Ein- und Austrittskanälen vorbeigleiten (15-19). Da der Kolben zur Hubbewegung sich gleichzeitig dreht, entsteht an der Zylinderwand eine schräge Bewegungsrichtung, der der Kolbenmantel (18) angepaßt ist, so daß entsprechend des Arbeitsganges die Kanäle geöffnet oder geschlossen sind.The embodiment according to claim 9 causes the piston, slots and openings, depending on the shape, slide past the inlet and outlet channels (15-19). Since the piston rotates at the same time as the stroke movement, the cylinder wall is created an oblique direction of movement to which the piston skirt (18) is adapted, so that the channels are open or closed depending on the operation.

Durch die Ausgestaltung nach Anspruch 10 werden die Gleitstellen an den Ein- und Ausströmkanälen abgedichtet. Dies erfolgt durch radial am Kolben beweglich angebrachte Teile - Flügel (19), Ring (20) -, die durch die Fliehkraft bei der Drehbewegung des Kolbens gegen die Zylinderwand (Abdichtstelle) gedrückt werden.Due to the configuration according to claim 10, the sliding points on the and outflow channels sealed. This is done by moving the piston radially attached parts - wing (19), ring (20) - by the centrifugal force at the Rotary movement of the piston against the cylinder wall (sealing point).

Werden die Abdichtteile an der Zylinderwand (21) angebracht, wirken die Teile durch Federdruck. Dies hat den Vorteil, daß der Kolben lediglich als glatter Schieber ausgeformt ist.If the sealing parts are attached to the cylinder wall (21), the parts act by spring pressure. This has the advantage that the piston is only smoother Slider is formed.

Die Ausgestaltung nach Anspruch 11 hat den Vorteil, daß die Dichtringe in der Kolbenbüchse durch leichte Spannung am Kolben abdichten. Dabei kann ein Ölkanal zwischen zwei Ringen geleitet werden, der für Schmierung und Kühlung sorgt (21). Hierfür bietet sich ein separater Ölvorratsbehälter an, in den Öl nachgefüllt, aber nicht gewechselt werden muß.The embodiment according to claim 11 has the advantage that the sealing rings in the Seal the piston liner by slightly tensioning the piston. It can be an oil channel between two rings, which provides lubrication and cooling (21). There is a separate oil reservoir for this, in which oil is refilled, but does not have to be changed.

Durch die Ausgestaltung nach Anspruch 12 ist es möglich, mit einem Kolben bei gleicher Schubrichtung mehrere Verdrängräume zu bilden. Dies geschieht, indem der Kolben wie der Zylinderraum, stufenweise abgesetzt, unterschiedliche Durchmesser aufweist (35). Die im I. und II. Verdrängraum entspannten Gase werden im größeren Raum III nachentspannt.The configuration according to claim 12 makes it possible to use a piston to form several displacement spaces in the same direction of thrust. This is done by the piston like the cylinder chamber, gradually offset, different diameters has (35). The gases released in the 1st and 2nd displacement space are released in the Relaxed larger room III.

Die Ausgestaltung nach Anspruch 13 ermöglicht durch entgegenlaufenden Kolben eine noch größere Nachentspannung und die Vorkomprimierung der Luft. Dies erfolgt durch gleiche Formgebung wie bei Anspruch 12, jedoch mit zwei Kolben (38, 22).The embodiment according to claim 13 enables by counter-rotating pistons even greater relaxation and pre-compression of the air. This takes place by the same shape as in claim 12, but with two pistons (38, 22).

Durch die Ausgestaltung nach Anspruch 14 wird die Anwendung des Hubdrehkolbens als Ventilschieber auch bei herkömmlich ausgestatteten Motoren mit Kurbelwellenbetrieb möglich. Dies erfolgt dadurch, daß eine Lagerung zur Drehung im Kolben eingebaut ist und entsprechender Zahnradantrieb in der Zylinderwand den Kolben dreht. Die Lagerung kann auch so ausgestaltet werden, daß sich nur der Kolbenmantel oder die Kolbenflügel drehen.Due to the configuration according to claim 14, the use of the lifting rotary piston as a valve spool also for conventionally equipped engines with crankshaft operation possible. This is done in that a bearing for rotation in the piston is installed and the corresponding gear drive rotates the piston in the cylinder wall. The storage can also be designed so that only the piston skirt or Turn the piston wing.

In den Zeichnungen ist die Erfindung bei verschiedenen Ausführungsbeispielen dargestellt. Durch die Mannigfaltigkeit der Anwendungsberiche wird hier exemplarisch auf die Funktion bei einem Hubkolben eingegangen. Darüber hinaus ergeben sich bei Verdrängermaschinen besondere Vorteile, die bei den Zeichnungen zum Ausdruck kommen.In the drawings, the invention is shown in various embodiments. The diversity of the application areas is exemplary here on the function of a reciprocating piston. Surrender beyond there are special advantages in displacement machines, which in the drawings for Expression.

The rotation ratio is determined by the size of the gears.

15-17 Piston shapes for reciprocating lobes - four-stroke engines.
The sealing points (rings -VII-, slider -VIII-, wing -IX-) slide over the inflow and outflow channels by rotating the pistons while simultaneously moving the stroke.
Depending on the piston shape, the cylinder heads are adapted to take advantage of the displacement space.
The simplest form for this are pistons with inclined piston rings (III). However, depending on the work performed, there is a lateral pressure against the cylinder wall. This can be prevented by double-sided sloping as with VII and IX. In piston form IX, the piston vanes (q) are pressed against the cylinder wall by their centrifugal force to seal the inflow and outflow channels.
With piston form VIII, only the slide valve (y) rotates with the control shaft (w).
18. Piston casing of a reciprocating piston for drawing 17 / IX.
As a result of the rotating and lifting movement, the direction of movement indicated by arrows takes place:
I - outflow channel (p) open,
II - inlet duct (o) opens,
III - intake valve closes (compression),
IV - both valves are closed (explosion.
19. Piston wing - centrifugal valve wing
They are guided in a radially movable manner on the piston (17 / IX) or control shaft (11) and are pressed against the piston wall by the centrifugal force during rotation.
20. Lifting piston as valve slide
The inlet and outlet openings are sealed by a metal ring (like piston rings). The piston seals on the piston due to its spring action on the cylinder wall by centrifugal force. The conical shape of this sealing ring also exerts pressure against the cylinder wall.
21. Cylinder with built-in sealing rings
All sealing parts against pistons are installed here so that the piston skirt consists of a smooth surface, cf. see drawing 18.
The inlet (o) and outlet channels (p) are sealed (s) by a conically shaped sealing ring, which seals in directions (against the cylinder wall and piston) due to its spring action as in drawing 20.
The cylinder rings (t) are held in place by parts of the cylinder liner and are pressed against the piston by their spring force.
In between is an oil channel (v), which is used to lubricate and cool the piston.
22. Two-cylinder four-stroke engine with two counter-rotating pistons and 4 displacements
While the displacements I and II work in four stroke, the exhaust gas relaxation of I and II takes place alternately in displacement III, displacement IV can be used for pre-compression.
23. Two stroke engine
The gas mixture does not reach the bearings on the drive shaft (which was previously required in the crankshaft chamber). The piston is lubricated and cooled separately through an oil channel (v). The cooling can also take place via an oil channel from the drive shaft.
24. Two-cylinder displacer with four displacements.
25. Two-cylinder displacer with opposing pistons.
26. Seals on piston rods with cylinder rings
For this, little space is required between the cylinder rooms (cf. 25).
27. Four-stage displacer.
28. 4 working steps of a four-stroke engine with 4 displacements and two-stage relaxation.
29. Eccentric shaft slide with a reduced diameter of the eccentric (shape of a crankshaft).
In accordance with the reduction, the compensation ring is larger and the stroke length is longer.
30. Eccentric shaft slide with a gear on the compensation ring, which is in one The sprocket rolls on the housing. The gear is half the size of the ring gear on Housing and thereby turns the compensating ring in the opposite direction.
31. Eccentric shaft spool as drawing 30, but for 2 axial pistons with counter functions.
32. Two eccentric shaft slides for moving and guiding one in a linear direction guided stamp (punching or the like). Drive of the compensation ring according to 8.
33. Two eccentric shaft slides for moving and guiding one in a linear direction guided stamp (punching or the like). Drive of the compensation ring according to 30.
34. reciprocating reciprocating piston, a cylinder space is reduced by the volume of the piston rod. This has the advantage that two operations are carried out with one piston. In the case of heat pumps, the large cubic capacity is ideal for compression, the small one for relaxation, and vice versa for a refrigeration machine.
If air is used as the medium, only one heat exchanger is required with an open circuit. Since the effort required for this is low, this system can also be used as a heater: outside air is compressed, flows through a radiator, releases heat there, is relaxed and expelled again.
35. Reciprocating pistons or reciprocating pistons with three displacement spaces: The displacement spaces I and II work as a four-stroke engine. The emission of the burned gases takes place in the displacement room III and is relaxed.
36. Eccentric shaft valve with fixed eccentric bearing and reciprocating piston drive
There are two gears and a gear roller on the drive shaft (g). The gears operate the eccentric and the compensation ring. A gear wheel connected to the piston rod slides on the gear roller and rotates the piston.
37. Reciprocating piston with rotating piston jacket
As in drawing 18, the rotating piston skirt performs the valve functions, while the core of the piston only carries out the stroke movement.
38. Two double-stroke pistons or stepped pistons with four displacement spaces
The two pistons run on the same cylinder axis in the opposite direction. With the same weight, this means complete swing compensation and enables vibration-free running when using the eccentric shaft slide (cf. 3, 14, 31).
Workflow as an internal combustion engine
Displacements I and II work staggered in four-stroke, displacement III subsequent relaxation of the gases when discharging from I or II, displacement IV pre-compression of the air for I or II.
The double-stroke piston offers significant advantages:

1. High compression through pre-compression,
2. larger space for relaxation than for compression,
3. has balanced working phases: The compression in I or II takes place by back pressure on the piston in III. The use of the driving force results in the alternation of the displacement I-III-II-III and takes place without a break, apart from the "dead point".
The valve control can be done by a camshaft or by the lifting rotary piston respectively. However, the latter is a simplification.
39. Lifting piston, rotatable, with a thrust bearing mounted around the piston rod in the piston
A gearwheel engages in grooves on the piston skirt to rotate the piston and also rotates it. The length of the grooves corresponds to the stroke of the piston.
A "connecting rod bearing" is possible in the axial bearing of the piston rod, and thus the movement of the piston in this embodiment as a valve slide can also take place with a crankshaft and connecting rod.
