Abstract

The control cylinder comprises a main housing (2) within which is located a piston (3). The cylinder is fixed to one section of the door and fame assembly whilst a shaft (4) that is connected to the piston is connected to the other half. Control valves (7) are located within the piston to control the opening and closing operations.

Description

L'invention concerne les mécanismes de commande d'emplacement relatif d'éléments mobiles (en particulier de l'angle d'ouverture d'éléments rotatifs)-par exemple portes, fentres, couvercles, dos de siège etc. The invention relates to mechanisms for controlling the relative location of moving elements (in particular the opening angle of rotating elements) - for example doors, windows, covers, seat backs, etc.

L'élément mobile 1 est joint à l'élément immobile 11 à l'aide d'un cylindre hydraulique 2 avec son tige-glissière 4. Piston 3 divise le volume intérieur du cylindre 2 en deux sections A et B jointes par un ou deux canaux 5a et 5b. Les canaux 5 sont fermés par des soupapes 7 qui sont commandées par des dispositifs 8. Les dispositifs 8 sont actionnés par un signal (ou force) donné par les capteurs de contrôle 6 des pressions limite Pmax et Pmin : quand la pression à l'intérieur dans la section dépasse Pmax la soupape est ouverte et le liquide est écoulé dans l'autre section ; quand la pression tombe au-dessous de pain la soupape se ferme. The movable element 1 is joined to the stationary element 11 using a hydraulic cylinder 2 with its slide rod 4. Piston 3 divides the interior volume of the cylinder 2 into two sections A and B joined by one or two channels 5a and 5b. The channels 5 are closed by valves 7 which are controlled by devices 8. The devices 8 are actuated by a signal (or force) given by the control sensors 6 of the limit pressures Pmax and Pmin: when the pressure inside in the section exceeds Pmax the valve is open and the liquid is discharged in the other section; when the pressure drops below the bread the valve closes.

Quand les soupapes sont fermées et l'effort sur l'élément mobile n'est pas important (la pression dans aucune des deux sections ne dépasse pas Pmax), alors le piston et l'élément 1 restent immobiles. When the valves are closed and the force on the movable element is not significant (the pressure in either of the two sections does not exceed Pmax), then the piston and the element 1 remain stationary.

Quand l'effort exercé par la main sur l'élément 1 est suffisamment grand (la pression dans une des sections a dépassé Pmin), le capteur de contrôle de la pression 6 actionne le dispositif 8 qui ouvre la soupape 7. Pare cette action la pression d'unité du liquide (et donc la pression sur le piston) tombe de plusieurs fois. Donc, pour que l'élément mobile puisse continuer à changer de position il lui faut appliquer la force 4 à 10 fois inférieure de l'effort initial. Quand l'élément mobile a pris la position voulue, son mouvement est freiné par la main, la pression du liquide dans la section tombe au-dessous de pain et la soupape se ferme. When the force exerted by the hand on the element 1 is sufficiently large (the pressure in one of the sections has exceeded Pmin), the pressure control sensor 6 actuates the device 8 which opens the valve 7. Pare this action the unit pressure of the liquid (and therefore the pressure on the piston) drops several times. Therefore, so that the movable element can continue to change position it must apply the force 4 to 10 times lower than the initial effort. When the movable element has taken the desired position, its movement is braked by hand, the pressure of the liquid in the section falls below the bread and the valve closes.

Si les capteurs de la pression et le mécanisme de commande de la soupape utilisent l'énergie électrique, il suffit alors d'avoir un seul canal entre les sections A et B et une seule soupape 7. Dans ce cas (Fig. 2) les deux canaux, les deux soupapes et les deux dispositifs d'ouverture-fermeture des soupapes sont combinés dans l'espace (5, 7,8). If the pressure sensors and the valve control mechanism use electrical energy, then it is sufficient to have a single channel between sections A and B and a single valve 7. In this case (Fig. 2) the two channels, the two valves and the two valve opening-closing devices are combined in space (5, 7,8).

Dans la première variante du dispositif mécanique (Fig. 1) il existe deux canaux (Sa et 5b) et deux soupapes 7a et 7b. La soupape 7a fait passer le liquide de A vers B uniquement, et la soupape 7b dans le sens contraire uniquement. Le capteur de contrôle 6 et le dispositif 8 sont des éléments constitutifs (9 et 12) de la soupape 7 (Fig. 3). Le capteur 6 est réalisé en forme d'une soupape 9 ; le dispositif 8 a la forme d'un cylindre creux 12 liant les soupapes 9 et 7. Les soupapes 7 et 9 sont pressées par un ressort commun 10. La base 13 de la soupape 7 a d'abord la forme d'un cylindre, et le bout la forme conique. Quand la soupape 7 est fermée, les surfaces cylindriques de la soupape 7 et de la base 13 se touchent légèrement. In the first variant of the mechanical device (Fig. 1) there are two channels (Sa and 5b) and two valves 7a and 7b. The valve 7a passes the liquid from A to B only, and the valve 7b in the opposite direction only. The control sensor 6 and the device 8 are constitutive elements (9 and 12) of the valve 7 (Fig. 3). The sensor 6 is made in the form of a valve 9; the device 8 has the form of a hollow cylinder 12 connecting the valves 9 and 7. The valves 7 and 9 are pressed by a common spring 10. The base 13 of the valve 7 first has the form of a cylinder, and the tip the conical shape. When the valve 7 is closed, the cylindrical surfaces of the valve 7 and of the base 13 touch slightly.

Dans la deuxième variante du dispositif mécanique les soupapes 7 (avec les capteurs 6 et les dispositifs 8) sont réalisées en forme d'éléments déformables (pouvant s'écarter) du piston. Pour cet effet le piston est fait entièrement ou partiellement d'un matériau capable de se déformer dans des conditions de travail, dans les limites de la déformation élastique. In the second variant of the mechanical device, the valves 7 (with the sensors 6 and the devices 8) are produced in the form of deformable elements (which can deviate) from the piston. For this purpose the piston is made entirely or partially of a material capable of being deformed under working conditions, within the limits of elastic deformation.

Dans la troisième variante du dispositif mécanique sont utilisées des soupapes de type d'une valve d'une chambre à air utilisé dans les pneus d'automobile. In the third variant of the mechanical device, valves of the type of a valve of an inner tube used in automobile tires are used.

Afin de faciliter l'ouverture de l'élément mobile à partir d'une position extrme, le cylindre a le diamètre plus grand à l'endroit où le piston se trouve dans la position extrme, ou bien des cannelures pour que le liquide puisse s'écouler librement d'une section à l'autre.  In order to facilitate the opening of the movable element from an extreme position, the cylinder has the largest diameter at the place where the piston is in the extreme position, or else grooves so that the liquid can s '' move freely from one section to another.
