 EMI1.1 
 



  Demande de Brevet d'Invention Introduite par 14. Raoul,Déslré  ", Joseph MOJ,.LE l, Ingénieur 01V11 . l, 72 Rue Ro7al.. !eru8, pour s IMIMENTS DE LOGIQUE PNBOMATIQCE A'PI80145 LIBRES      
 EMI1.2 
 DI'8'1 TYLL$ Les principales fonctions logiques Pas , E6al1 t et NI sont   obtenues.,   comme le montrent les figures I, 2   et 3     .l'aide   de pistons libres différentiels A ,   B   et C. L'alimenta-   @   tion permanente en fluide sous-pression (liquide ou gaz; air   comprimé   par exemple ) s'effectue en X, Les pistons A, B, C, 
 EMI1.3 
 sont donc repasssés vers la droite , en 10absence de signal zur. 



  Dans les figures I et 3 l'air comprime entrant par X peut 
 EMI1.4 
 s'échapper vers la sortie Y ; dans la figure 2 au oon%raire , -¯le passage de X vers Y setrouve interrompu et le circuit Y est mis à l'échappement par l'orifice E. Grâce à leur section plus grande , les pistons B ou C sont repoussés vers la gauche si 
 EMI1.5 
 l'alimentation entlU1de sous-pression s'effectue par y , 9 y, ou Y2 . Selon la forme donnée aux pistons , les garnitures d'étan- chéité sont placées en 2-3-4-5 dans le bâti 1 ( figures 1 & 2 ) ou sur les pistons ( figure 3 ).

   Dans le premier   cas ,  les fonds ou extrémités des pistons sont sphériques   afin   de facili- ter leur passage sur les garnitures d'étanchéité et d'assurer une meilleure obturation en prenant appui sur les garnitures 2   ,de   la figure I ou sur les garnitures 3 et 4 de la figure 2. 



  ¯¯Dans le second cas ,   figure 3 ,  les fonds des pistons A et C sont concaves afin de faciliter la répartition de la pression du fluide entrant par X et par y2. Notons également que par   simplification   de la figure 2 on obtient un clapet d'intercom-

 munication permettant le passage de la canalisation 7 à la sor-   -,tie   E ou de la canalisation 9 à la sortie E, sans   possibilité   -,.de passer de 7 à 9 et réciproquement, Il suffit de ne conserver 
 EMI1.7

 EMI1.8 
 située a gaucne. i=in , si on supprime e4Écuimm iorixiaa r on obtyezrtn clapet de non-retour de E vers 9 ( figure 2).

  Patent Application Submitted by 14. Raoul, Déslré ", Joseph MOJ, .LE l, Engineer 01V11. L, 72 Rue Ro7al ..! Eru8, for s IMIMENTS DE LOGIQUE PNBOMATIQCE A'PI80145 FREE
 EMI1.2
 DI'8'1 TYLL $ The main logic functions Pas, E6al1 t and NI are obtained., As shown in figures I, 2 and 3, using free differential pistons A, B and C. permanent tion in pressurized fluid (liquid or gas; compressed air for example) is carried out in X, The pistons A, B, C,
 EMI1.3
 are therefore passed again to the right, in the absence of signal zur.



  In figures I and 3 the compressed air entering through X can
 EMI1.4
 escape to exit Y; in figure 2, the passage from X to Y is interrupted and the Y circuit is exhausted through the orifice E. Thanks to their larger section, the pistons B or C are pushed back towards the left if
 EMI1.5
 the entlU1de underpressure supply is effected through y, 9 y, or Y2. Depending on the shape given to the pistons, the seals are placed at 2-3-4-5 in the frame 1 (figures 1 & 2) or on the pistons (figure 3).

   In the first case, the ends or ends of the pistons are spherical in order to facilitate their passage over the seals and to ensure better sealing by resting on the seals 2, in figure I or on the seals 3. and 4 in Figure 2.



  ¯¯In the second case, figure 3, the bottoms of pistons A and C are concave in order to facilitate the distribution of the pressure of the entering fluid by X and by y2. Note also that by simplification of Figure 2 we obtain an intercom valve
 EMI1.6
 munication allowing passage from pipe 7 to outlet -, tie E or from pipe 9 to outlet E, without the possibility -,. of changing from 7 to 9 and vice versa, It is sufficient to keep
 EMI1.7
 z 1 ---. r. as part B of the free piston and remove all the part
 EMI1.8
 located on the left. i = in, if we remove e4Écuimm iorixiaa r we obtain a non-return valve from E to 9 (figure 2).
