DE102009040270A1 - Ring piston machine, particularly motor, pump or compressor for generating kinetic energy or electrical energy, has two overlapping piston rings by which control of piston takes place - Google Patents

Abstract

The ring piston machine has two overlapping piston rings by which the control of the piston takes place. The two piston rings are connected by an inner toothing and an eccentrically supported toothing. The accelerating and decelerating movement of the piston carrier rings and the pistons takes place by the eccentrically supported toothing and the shaft toothing in hypocycloid form.

01. Introduction

The engine technology for internal combustion engines with pistons as well as the steam engine technology has in principle remained the same since the first gasoline engine / steam engine. Pistons are first accelerated in one direction, decelerated, come to a halt, accelerated in the other direction, retarded, come to a stop, and so on. These changes are a huge waste of energy.

Since the combustion energy contained in an energy source is converted into propulsion energy in piston engines via a variety of mechanical parts (piston, connecting rod, crankshaft, clutch, gimbal, timing chain, camshafts, valves, valve springs and much more), only a small part exploited this energy (35-45%).

So far, there has only been a further development of the old piston engine technology (the steam engine technology is de facto no longer applicable).

The Witt type rotary piston engine with desmodromic control (forced control) is a new development in internal combustion engine technology, steam pressure, water pressure and air pressure motor technology as well as in pump and compressor technology.

02. Preliminary considerations

• a. in a straight cylinder, a piston has to be moved back and forth twice to return to its original location so that an ignition can be repeated. The piston moves along a line, ie one-dimensionally. In a long cylinder (torus) bent into a circular ring, the piston moves in one direction only (only out), but still arrives at its place of origin. This piston moves along a curved line, but in one area, ie in two dimensions.
• b. If one transfers a rotating movement (toothed wheel) into a straightforward forward movement (toothed rack), the speed of the toothed rack is also constant at a constant rotational speed of the toothed wheel. Here, the gear is stored centrally ( 1 ). With an eccentric bearing of the gear, there are the following changes: To ensure that all teeth of the gear mesh, the rack must be adjusted. She gets the waveform of a shortened cycloid ( 2 ). During the first half turn of the gear, the rolling length is smaller (fewer teeth) than in the second half turn. At a constant rotational speed of the eccentrically mounted gear, the "shaft rack" accelerates and decelerates ( 2 ).
• c. If you bend now the straight "shaft toothed rod" to a circular ring (toothing inwards), and if you let inside eccentrically mounted gears in this "wave tooth ring" grab, you get a planetary gear with the property that with constantly rotating eccentric planetary gears, the outer ring gear alternately accelerating and decelerating ( 3 ). The inner shape of the annulus has the shape of a shortened hypocycloid. This eccentrically mounted planetary gear is referred to below planetary gear type Witt.

d. Placing two of these planetary gear Witt superimposed, with each two of the eight inner, eccentrically mounted gears on each axis (four axes) mounted offset by 180 °, which accelerates a circular ring in the moment in which the other annulus delayed ,

03. History of the piston engine

The two previously known piston engines, which were also built (type Beck, 1909 and type Essemble 1912) have an oscillating (reciprocating) movement and an axial power transmission (axis in axis) to a lying behind gear. The control is done here via connecting rods and rods. In the Essemble engine, the circular cylinder rotates about its own axis.

The so-called Strebinger engine ( www.strebinger.de ) has only one direction of movement of the piston; however, one piston pair comes to a stop before the other pair of pistons starts to move. Power transmission here: axial. Whether he was ever built is unknown.

In the patent application DE 102005020221 A1 (Rotary piston machine) is the accelerated and delayed motion in a rotational movement described. This "movement in motion" has been known for years. Again, however, of a "hinge-like axis" and the most diverse drives for generating this movement in motion (elliptical gears, alternating gears, pivoting levers, connecting rods, connecting rods, crank gears, etc.). Was shown in this application, a rotary engine and no piston engine. The patent office had cited the "force-locking" transmission mechanisms

The piston engine according to patent EP 0021765 A1 and Patent Application 102008038708.8-15 has indeed two piston carrier rings, but also two ring cylinders (Tori), These are arranged so that the engine has no compression stroke.

The Witt type rotary piston engine described below has a completely different control and drive system.

04. mode of operation (schematically) - here an example with eight pistons

The ring piston motor, type Witt consists mainly of two piston carrier rings, on which 4 pistons are mounted on the outer edges per piston carrier ring in this example (also possible 6, 8, 10 ... piston). The pistons move in a cylinder (torus) bent into a circular ring. The piston shape corresponds to the cylinder shape. Each piston carrier ring is internally provided with a toothing (ring gear). In this toothing, which has the form of a shortened hypocycloids grip per piston carrier ring each four eccentrically mounted gears (planet gears). The circumference of a planetary gear in this example is one quarter of the circumference of the toothing of the ring gear ( 4 , Level 1 ).

The eccentrically mounted on four auxiliary shafts gears (planetary gears) in conjunction with the piston carrier ring (ring gear), the planetary gear, type Witt.

The two piston carrier rings are connected via the 2 × 4 = 8 eccentrically mounted gears, which are mounted on four auxiliary shafts desmodromisch (positively controlled) with each other.

Since the pistons fixedly connected to the two piston carrier rings (by a phase-shifted arrangement of the piston carrier rings to each other) are accelerating and decelerating, there is in the absolute movement of the system in one direction, a relative "pulsating" movement between the pistons ( 5 ).

The pistons move away from each other and approach each other as they move, and the work spaces between the pistons, in the torus space. The four Otto cycles (aspiration, compression, operation, ejection) are distributed over four sectors in the torus (2 × 4 in this example). The suction and discharge takes place via slots in the cylinder wall, which are automatically opened and closed by the piston during "hiking" without additional effort.

Since the two Kolbentragerringe are connected to each other desmodromic, the relative movement of the pistons can only be done to each other, if the absolute movement of both piston rings takes place in one direction only (engine must be started to be turned on).

05. Power transmission

The kinetic energy of the pistons resulting from the combustion pressure is transmitted to the four auxiliary shafts (two levels) via the two pistons and the eight eccentric gears. On these four auxiliary shafts, there is once again one gear per secondary shaft in a third plane. These four, this time centrally mounted gears (planet gears), engage in the fifth mounted in the middle of the system gear (sun gear) and transmit the force to the main axis, which is also the drive axle ( 4 , Level 3 ).

Since with one revolution of the system 16! Explosions take place, the engine is both slowly rotating and because of its operation very high speed.

By changing the gear ratio in the planetary gear in the third level of the torque curve can be changed.

On a transmission may possibly be completely dispensed with because of the revving of the engine (similar to the electric motor).

06. Piston lubrication

The slightly curved pistons (shape and size adapted to the torus) have piston rings at both ends. Because the pistons are firmly connected to the piston carrier rings, and the piston carrier ring is mounted, the pistons "theoretically" have no contact with the cylinder wall of the torus. Only the piston rings slide along the cylinder wall.

The lubrication of the pistons can be done either by injection at the moment of "flying through", or in the form of an addition to the energy source.

07. cooling

Most of the heat generated at the explosion sites is dissipated by means of water or oil (possibly air cooling sufficient).

08. Engine components

The Witt type rotary piston engine consists of eight main components, ignoring the ancillary components:

• 1. Two piston carrier rings
• 2. Eight pistons with piston rings
• 3. Eight eccentric gears / planet gears
• 4. Four centric gears / planet gears
• 5. One main gear / sun gear
• 6. Four side waves
• 7. A main shaft
• 8. Two housing parts

09. Efficiency

A calculation of the energy yield has not been carried out so far. Since all moving masses of the Witt rotary piston engine have only one rotational movement and, in addition, the crankshaft and the complete valve train are eliminated, it can be assumed that the efficiency is higher than that of a normal engine. Gasoline engine: Ring piston engine: For a work cycle (suction, compression, working, ejection) two crankshaft revolutions are required. Since a work cycle is distributed among four sectors in the torus, suction, compression, operation, and ejection are constantly repeated after each passage of the piston through a sector. Single-cylinder engine with one spark plug: 0.5 ignitions per revolution. Four-cylinder engine with one spark plug: 4 firings per revolution. Four-cylinder engine with four spark plugs: 2 firings per revolution. Eight-cylinder engine with two spark plugs: 16 ignitions per revolution. Eight-cylinder engine with eight spark plugs: 4 firings per revolution. Twelve-cylinder engine with three spark plugs: 36 ignitions per revolution
