The invention relates to a rotating motor in which two or several intermeshing screws are used, the type of piston a steam engine or the blade of a turbine has the effect of a flowing or transform a pressurized fluid directly into a driving force.

It is a well-known fact that when a screw is placed in a cylinder, whose outer diameter would correspond exactly to the inner diameter of the cylinder, and one let a flowing or pressurized mass of liquid flow from one side of the latter penetrate, the greater part of the living force of the same would not be made usable. After acting on the first turn of the screw, the liquid would simply the free space between the cylinder wall, along the side surfaces of the aisles follow to at the other end of the cylinder without any appreciable work being done to have to escape again.

The new arrangement is based on the idea, the effect, which a liquid can exert on a snail, harness it in the most perfect way by two or more snails acting in a peculiar manner to one another are employed are arranged in a total of exactly closing in one and the same cylinder are. The wings of one snail are for this purpose in that by the wings of the other snail intermeshing space formed at a corresponding distance from each other so arranged that they do not touch at any point. The so arranged, with their threads interlocking snails make a deviation of flowing or pressurized liquids Resistance corresponding to the mass and completely absorb its vital force, to turn it into a driving force.

The invention therefore offers its utility in any liquid engine for the previously used means of hunting, such as pistons, connecting rods and crank, turbine blade etc., complete replacement. However, it can just as well be used as a means of transmission for pumps or propellers, etc.

In the accompanying drawing, for example, an engine is shown, which with the new Is equipped transmission means.

In the rear closed cavity of the bed AA ¹ , the intermeshing screws mounted on shafts are arranged. The gears g and c seated on the rear part of these shafts transmit the movement of the worms to a gear wheel d wedged onto the transmission shaft. The liquid penetrates through the

openings C and, after it has set the screws in rotation, escapes through outlets D. H. In this space a rotation is generated by the action of the liquid on the screws or, conversely, by the action of the screws on the liquid and transmitted to the gear transmission gcd. This space is so constructed that the inner wall adapts exactly to the cylindrical shape of the individual snails. However, this depends on the liquid to be used, but in such a way that, when the motor is at rest, the screws can rotate freely without being subjected to the hydraulic action. In the cover A of the rear closed cavity, two bushings α α are arranged, into which the guide rods h are screwed. These rods serve to accommodate the screws L. provided with hollow axes. They also have a longitudinal bore through which the oil or the like is passed to lubricate the screws L rotating on the rods. The opposite end of each worm is fastened by means of the split pins s s on a shaft r, the front end of which is screwed into a cross head η which in turn rotates in a ball bearing. The latter is mounted in a slide T which slides lengthways on the bed A1 in a rack-and-pinion guide so that it can be adjusted automatically or by hand by any suitable device. Each of the shafts r has a gear wheel g and c of the same size, each of which is provided with a guide wedge j which fits into the longitudinal groove arranged along the entire length of the shaft. This arrangement shown in Fig. 1 and 2 allows a longitudinal movement of the shafts r with the carriage T and worms L attached to them, while the gears g and c are always held in place. The engagement of the gears g and c ensures the parallel running of the worms L, which always turn in such a way that their threads never touch. One of the wheels g or c transmits the movement to the wheel d keyed to the receiving shaft. The bearing block q for the receiving shaft can be attached to the bed A1 of the motor. Flanges, which are located at the foot of this bracket, can be used to hold the ball bearing shells for drives g and c (Fig. 1 and 2). The length of the snail can be interrupted to a certain extent V, so that a neutral free space is formed, so to speak. As soon as this is set in the taper A F of the rear space, the liquid penetrating through openings C pours out directly through the outlet D without affecting the screw. In the case of such a screw consisting of two separate pieces, two pairs of screws acting in opposite directions can therefore be arranged, as shown in FIGS. 1 and 2 The direction of rotation of the transmission shaft is opposite. The pitch of the worm is not even, but increasing, which follows a certain law. You can therefore achieve different speeds by moving one more or less wide or narrow sets the split pitch of the worm in the taper AF. Pateντ claims: 1. Helical gear capsule mechanism with reversing, characterized by two axially adjustable screw pairs (L) rotating in opposite directions, of which .
