DESCRIPTION Number wreath 3DX »: *; D2X- rotary piston machine.

Motors with cylinders arranged in a circle are known. (Radial engines ) There are also known motors whose cylinders are arranged in a star shape around a stationary one Rotate the crankshaft. (Rotary motors). All of these motors have the motion conversion in the center of the star and, like all piston engines, use the xub- in a rotary movement of the crankO With the conventional crankshaft are certain Disadvantages linked. There are lateral forces on the cylinder wall. The piston rod t connecting rod), because of these forces, cannot fall short of a certain length of time ( Ideally - infinitely long piston rod). The lifting height can be a certain minimum not fall below (torque J; upper and lower L dead center can be set in sveg speed diagrams do not vary.

in the 4-act version, per cylinder for all crankshaft machines only one working stroke for 2 rotations of the output shaft.

The conventional valve controls require a detrimental one constructive effort.

For reasons of performance, the outlet valve opens (overlaps) generally about 40 ° to 60 ° before reaching the bottom dead center.

Air injection near bottom dead center to achieve it The most complete possible combustion (detoxification) is therefore part of the workflow problematic and ineffective.

Especially the detoxification (complete combustion) of the explosion work machines is of such importance today that every effort is worth it.

The prerequisite for such a detoxification is a correspondingly variable one Movement meciianism (conversion of the linear movement into a rotating zewegun.

The construction of a shown in the accompanying drawings A toothed ring engine is very simple and avoids all the disadvantages of a piston engine, as stated above, without any other disadvantage in purchase to have to take.

The motor consists of the following elements: (see @ chg.I and II) 1. The runner with all (la) with straight guide t lb) with cylinder bores t lc) with inlet and outlet slots t ld) 2. the cover for the inlet side (pa ) for the outlet side (2b) with the holes for inlet control (2c) for outlet control (2d) for spark plugs (2e) setting for retrieval (2f) 30 The ring gear that The conversion of the lifting movement into a rotary movement with an optimal flank design conveyed.

4. Ben piston with rollers for the running ring (4a). for straight guidance (4t) for retrieval (4c) 5. The cylinder liners.

How it works: The rotor with cylinders and pistons rotates, the pistons are based on the gear rim, the side forces that occur are in the line of origin, intercepted by the co-rotating straight line.

This means that the piston (without the piston pin) can be designed in the simplest possible way will.

It is sucked in through the slots in one of the covers, and it is ejected (Exhaust) through the slots in the other cover The sealing is done by ring-shaped Bars on the runner slots The version shown is a 3-cylinder engine represents, whereby the ring gear is designed in such a way that per revolution of the rotor (= output shaft ) and there are 4 working strokes per cylinder 0 The 3-cylinder engine has, on the output shaft, the characteristics of an engine with 12 cylinders (two-stroke) and with 24 cylinders (4 stroke) as is known (for sealing reasons) always some reservations about slot controls.

The ring gear motor can now also be equipped with valves and instead of letting the cylinders rotate, the can also be used in a conventional manner Rotate the ring gear.

Normal valves (poppet valves) require a not inconsiderable one constructive effort.

With a "tube piston valve" (see drawing III) (also for conventional in-line engines) significant structural and technical simplifications Achieve advantages, e.g. very coarse valve cross-section and the option of one Manifold injection is practically direct injection into the combustion chamber close.

For demonstration of a "valve-controlled n ring gear motor with Ring gear output shaft is a construction example in the drawings iVa; IVb; IVc; IVd; shown, the engine consists of the following elements 1 cylinder head ring 2 tubular piston valves 3 cylinders 4 pistons 5 piston rod 6 cam disk 7 sprocket rotor 8 Ignition distributor 9 Cover 10 Intake pipe 11 Exhaust pipe 12 Straight guide The ring gear is designed, for example, so that the expansion and discharge strokes are significantly larger are used as a suction and compression stroke (discharge of only completely reacted gases k Detoxification) A valve overlap, long is no longer necessary0 The ring gear is designed in such a way that (with four-stroke behavior) each piston per revolution of the output shaft performs several work strokes.

Claims (1)

installment entitlements: A Combustion engine with cylinders arranged in a star shape in one Runner, characterized in that the cylinder cover is in the center of the star that the pistons, which are designed without a piston pin, are on a stationary one External links support the ring gear so that this support takes place over needles that the piston rollers engage in straight guide slots that the gear rim flanks can be designed in such a way that the upper or lower iot point curve optimally corresponds to the Compression or Verrehnungsvorgang can be adapted that the ahnkranz Can be designed so that per revolution of the power shaft (rotor) per cylinder more working stroke can be achieved with a change in the number of cylinders (Type change) No structural changes are required that the lubricant at the same time can be used as a coolant that near the bottom dead center In the working stroke, Laft is injected, which causes the residual combustion of the HO (detoxification ) and the increased performance leads to the fact that the motor can be used as a pump, that the pump swaps the suction side and pressure side when the direction of rotation is changed. B Patent claims internal combustion engine with a star-shaped arrangement Cylinders, characterized in that the cylinder head is formed as a ring is attached to the inside of single cylinders that the control over novel "tube piston valves" that the valve control takes place via cam disks happens that are directly connected to the output shaft V no transmission medium necessary ) that the friebwrk (ring gear) can be designed so that the torque remains constant from top to bottom dead center, b) that the stroke height of the expansion stroke and the discharge stroke is considerably larger than the suction and compression stroke, c) that the dead center can be designed so that at the beginning of the suction stroke or the ejection stroke, the corresponding valves are fully open (or at the end fully closed) without the need for an "overlap". t detox ) Characterized in that without influencing the achievable torque of the hub can be kept extremely small (in the construction example shown is the tiub 20 mm the bore 60 mm).
