Abstract

The invention relates to a device which makes it possible to transmit a movement between two parts without the intervention of a physical link. It consists of a cylindrical magnetic piston (1) inserted into a non-magnetic guide tube (2). An annular magnet (3) or an electromagnetic coil can be slipped over the outside of the guide. The device according to the invention is particularly intended to be used for carrying out physics experiments.

Description

La présente invention concerne un piston qui peut transmettrc un mouvement à un autre organe sans lien materiel ou recevoir dans le mêmes conditions un mouvement de ce même organe. The present invention relates to a piston which can transmit a movement to another member without material link or receive under the same conditions a movement from this same member.

Habituellement, les pistons moteurs ou résistants sont solidaires d'une tige comme dans les pompes, ou d' une bielle comme dans les moteurs; les efforts transmis entre piéces peuvent être intenses. Usually, the engine or resistant pistons are integral with a rod as in pumps, or with a connecting rod as in engines; the forces transmitted between parts can be intense.

Dans 1' appareil suivant 1' invention, le couplage entre piston et organe de commande ou de réception du mouvement est magnétique ou électro magnétique; les efforts transmis entre piéces seront modérés. In one device according to the invention, the coupling between piston and member for controlling or receiving the movement is magnetic or electromagnetic; the forces transmitted between parts will be moderate.

L' appareil est constitué d' un piston cylindrique magnétique ou magnétisable guidé de façon douce dans un tube de faible épaisseur, éventuellement transparent dont la substance est amagnétiquesur la surface exterieure du tube peut coulisser avec un jeu faible un aimant annulaire en ferrite ou une bobine de fil de cuivre qui jouera le rôle d' un électroaimant.Suivant la disposition des pôles magnétiques, le piston et l'aimant annulaire ou la bobine s'interpénétrent ou s' expulsent. The device consists of a magnetic or magnetizable cylindrical piston gently guided in a thin tube, possibly transparent whose substance is nonmagnetic on the outside surface of the tube can slide with a weak play an annular ferrite magnet or a coil of copper wire which will play the role of an electromagnet. Depending on the arrangement of the magnetic poles, the piston and the annular magnet or the coil interpenetrate or are expelled.

Le piston pourra être actionné par un fluide introduit dans le tube guide et interagir avec l'aimant annulaire.En déplacant l'aimant annulaire par un dispositif approprié on agira sur le piston
Tel qu'il est présenté,le dispositif comprend un piston magnétique(l) guidé par un tube(2) sur lequel peut glisser un aimant annulaire(3).The piston can be actuated by a fluid introduced into the guide tube and interact with the annular magnet. By moving the annular magnet by an appropriate device we will act on the piston
As presented, the device comprises a magnetic piston (l) guided by a tube (2) on which an annular magnet (3) can slide.

Le dispositif suivant l'invention est particuliérement destiné à être utilisé pour des expétiences de physiques variées (étude de mouvement, de forces,modélisation,magnétisme et électomagnétisme)  The device according to the invention is particularly intended to be used for various physical experiments (study of movement, forces, modeling, magnetism and electromagnetism)
