The invention relates to a method and a device for the smooth transmission of motion or for the smooth coupling of two moving elements, which are used in various branches of technology Can find application. It is preferably a very fine primary adjustment movement, the z. B. is carried out automatically by an instrument, for a second

o transferring the switching or adjusting device or a servomotor smoothly, whereupon then the required setting by the relevant switching device or the servomotor or control is carried out.

The drawing shows an exemplary embodiment of the device for executing of the method according to the invention schematically.

In the drawing, α is an angularly bent pipe. The tube is supported on the one hand in a tip b , on the other hand it grips with its lower open end over the conical nozzle of a tube c. The upper end of the tube a is provided with a nozzle d . On the tube, a lever construed o. The like. E on, can be pivoted by the esin the direction of the arrow to the right dare axis. Opposite the nozzle are the openings of two Z-shaped bent tubes f and g, which open on the other side near the bottom and the cover of a cylinder // which, in a manner not shown in the drawing, is horizontal

39179G Guides lies and can shift in these. A piston / is arranged in the cylinder, the rod k of which is fixed. The operation of the facility is as follows. A liquid or a gas, preferably compressed air, is supplied through the pipe c. The air flow flows into the pipe α and flows out of the nozzle d . Since the nozzle is opposite the openings of pipes f and £, ίο the compressed air is blown through pipes f and g into cylinder Ii. Assuming now that the nozzle d was just opposite the tube g , the air would only penetrate through the tube g to the right of the piston i into the cylinder //. As a result, an overpressure would arise on this side and, since the piston i is stationary, the cylinder / 1 would move to the right, with the tube f then facing the nozzle d. If the movement of the cylinder h is so great that a greater part of the air enters the pipe f than the pipe g, then a greater pressure would arise to the left of the piston ί, and the cylinder would move as to the left again. A state of equilibrium will therefore be established in which the openings of the tubes f xmd g. face the nozzle d in such a way that the same amount of air flows into both tubes i, i.e. the same pressure j is maintained on both sides of the piston i. If the pipe α is now pivoted to the right or left by the lever e , the cylinder h must join in this pivoting movement, because every time the nozzle is shifted in relation to the openings in the pipes f and g facing it, a pressure difference immediately arises on the two sides of the piston , which causes a movement of the cylinder in the direction in which the nozzle d has shifted. The device thus forms a follow-up system, ie a system which consists of two parts which are coupled to one another in such a way that the movement of one part is transmitted to the other part without friction due to the coupling and the transmission. Losses can arise. It is therefore possible, even if very small forces act on the lever c , to transfer the movements carried out by the easily pivotable tube ei to a machine part that is relatively difficult to move, namely the cylinder Λ. The energy required to carry out the movement of the cylinder d is provided by the compressed air flow, which, however, does not prevent the movement of the tube α in any way. Of course, the method can also be carried out in a different way, so instead of the to-and-fro movement of the cylinder, a rotary movement can also be produced, or the nozzle d can be given a straight or any other movement instead of the oscillating movement. The idea of the invention is based on the fact that when a movement is transmitted from one element to another, energy and directional determination or control are separated from one another in such a way that the primary moving element only controls the direction of the secondary moving element, without any energy for moving the controlled element To have to deliver element, while the energy required to move the secondary element is supplied from the outside so that it does not affect the control movement of the primary element. Patext claims: i. Method for the smooth transmission of a movement from a moving primary element to a moving secondary element or for the smooth coupling of two elements, characterized in that the primary element serves only to control the direction in which the energy is transmitted to the secondary element, without energy itself to this, while the 9 ^C energy required to move the secondary element is supplied from the outside in such a way that the movement of the primary element is not influenced by it. 2. The method according to claim 1, characterized in that the movement of the Pri- 9i märelementes used to change the direction of a liquid or gas flow which is supplied as kinetic energy for the secondary element and depending on its direction controlled by the primary element causes its movements. 3. Apparatus for carrying out the method according to claim 1, characterized through a nozzle executing the primary movement, from which compressed air or hydraulic fluid against two adjacent openings from after the lid and bottoms one Cylinder o. The like. Leading pipes flows, so that in the cylinder, the piston solidly is arranged according to the movement of the nozzle on one side or the other Overpressure arises, which results in a corresponding movement of the cylinder. 1 sheet of drawings.
