Description

  

  Compresseur de fluide élastique avec moteur de commande<B>à</B> vapeur.    La présente invention se rapporte<B>à</B> un  compresseur de fluide élastique avec moteur  de commande<B>à</B> vapeur, comportant au moins  un cylindre de compression avec chemise<B>de</B>  refroidissement permettant de le refroidir au  moyen<B>de</B> vapeur     d'écfiappement    venant du  moteur de commande du compresseur.

   Elle  présente la particularité que l'intérieur de la  chemise de refroidissement du cylindre de  compression est pourvu d'une     cloison-guide,     formant chicane, établie de manière<B>à</B>     dîriger     la vapeur d'échappement dans la chemise de  refroidissement de     facon   <B>à</B> la faire passer  sur toutes les parties de la paroi du cylindre  et<B>à</B> empêcher ainsi la formation de poches       d air.     



  Le dessin ci-joint représente,<B>à</B> titre  d'exemple,     une    forme d'exécution de l'objet  de l'invention, telle qu'elle s'emploie, par  exemple, sur les locomotives pour alimenter  les freins     Westinghouse    en air comprimé.  



  La     fig.   <B>1</B>     en    est une élévation latérale,  partie en coupe verticale, et  La     fig.    2 en est une coupe horizontale,    Le compresseur d'air représenté comporte       une    tête<B>à</B> tiroir de vapeur<B>1,</B> une paire de  cylindres moteurs<B>à</B> haute et<B>à</B> basse pression,  2,<B>3,</B> une paire<B>de</B> cylindres de compression  d'air<B>à</B> haute et<B>à</B> basse pression, 4.<B>5.</B> une  section intermédiaire entre ces deux paires  de cylindres et une tête<B>à</B> valve de com  pression<B>7</B> prévue aux cylindres de compression.  



  Le cylindre moteur<B>à</B> haute pression 2  renferme un piston relié par la tige<B>8 à</B> un  piston contenu dans le cylindre de compres  sion<B>à</B> basse pression<B>5</B> et le cylindre moteur  <B>à</B> basse pression<B>3</B> renferme un piston relié  par une tige<B>9 à</B> un piston contenu dans le  cylindre de compression<B>à</B> haute pression 4.  



  Le cylindre de compression<B>à</B> haute pres  sion 4 est pourvu d'une chemise de refroidis  sement<B>11</B> reliée<B>à</B> un     eonduit    12 allant<B>à</B>  l'orifice d'échappement de vapeur<B>13</B> du com  presseur. Cette chemise de refroidissement<B>Il</B>  est destinée<B>à</B> être parcourue par de la va  peur d'échappement et renferme une     cloison-          guide,    formant chicane, 14, s'étendant en  forme d'hélice autour de la paroi du cylindre      de compression 4, cette     cloison-guide    étant  venue de fonte avec la paroi dudit cylindre  et avec sa chemise de refroidissement et étant  disposée pour diriger la vapeur d'échappement  autour de la paroi dudit cylindre, comme  indiqué par les flèches,

   de façon<B>à la</B> faire  passer sur toutes les parties de cette paroi,  cette vapeur d'échappement se déchargeant  par     Forifice    d'échappement<B>15</B> prévu<B>à</B> l'ex  trémité inférieure du cylindre de compression  4. La vapeur d'échappement franchissant  ainsi toutes les parties de la paroi du cylindre  de compression, il ne se forme pas de poches  d'air en contact avec cette paroi, ce qui  permet d'utiliser la totalité de la surface de  la paroi du cylindre de compression pour  des buts de refroidissement.  



       rne    disposition similaire peut être prévue  pour le cylindre de compression<B>à</B> busse  pression, si on le désire, mais ordinairement  la pression du fluide comprimé dans ce cylindre  est trop faible pour occasionner     une    augmen  tation de température correspondante du fluide  comprimé, de sorte que l'écoulement normal  de la vapeur d'échappement par la chemise  de refroidissement précitée sera suffisamment  efficace pour les buts de refroidissement  envisagés.



  Elastic fluid compressor with <B> steam </B> control motor. The present invention relates <B> to </B> an elastic fluid compressor with <B> steam </B> control motor, comprising at least one compression cylinder with <B> cooling </B> jacket allowing it to be cooled by means of <B> </B> exhaust steam from the compressor drive motor.

   It has the particularity that the inside of the cooling jacket of the compression cylinder is provided with a guide partition, forming a baffle, established in such a way <B> to </B> to draw the exhaust vapor into the jacket. cooling so as to <B> to </B> pass it over all parts of the cylinder wall and <B> to </B> thus prevent the formation of air pockets.



  The accompanying drawing represents, <B> by </B> by way of example, one embodiment of the object of the invention, as it is used, for example, on locomotives to supply Westinghouse compressed air brakes.



  Fig. <B> 1 </B> is a side elevation, part in vertical section, and FIG. 2 is a horizontal section, The air compressor shown has a <B> with </B> steam drawer head <B> 1, </B> a pair of engine cylinders <B> at </B> high and <B> at </B> low pressure, 2, <B> 3, </B> a pair <B> of </B> air compression cylinders <B> at </B> high and < B> at </B> low pressure, 4. <B> 5. </B> an intermediate section between these two pairs of cylinders and a head <B> with </B> com pressure valve <B> 7 < / B> provided for the compression cylinders.



  The high pressure <B> </B> engine cylinder 2 contains a piston connected by the rod <B> 8 to </B> a piston contained in the <B> </B> low pressure compression cylinder < B> 5 </B> and the engine cylinder <B> at </B> low pressure <B> 3 </B> contains a piston connected by a rod <B> 9 to </B> a piston contained in the high pressure <B> </B> compression cylinder 4.



  The high pressure <B> </B> compression cylinder 4 is provided with a cooling jacket <B> 11 </B> connected <B> to </B> a conduit 12 going <B> to </B> the steam exhaust port <B> 13 </B> of the compressor. This <B> Il </B> cooling jacket is intended <B> to </B> to be traversed by the exhaust gas and contains a guide partition, forming a baffle, 14, extending in the form of a 'propeller around the wall of the compression cylinder 4, this guide partition being made of cast iron with the wall of said cylinder and with its cooling jacket and being arranged to direct the exhaust vapor around the wall of said cylinder, as indicated by the arrows,

   so <B> à la </B> pass over all parts of this wall, this exhaust vapor discharging through the exhaust port <B> 15 </B> provided <B> at </B> the lower end of the compression cylinder 4. As the exhaust vapor thus passes through all parts of the wall of the compression cylinder, no air pockets are formed in contact with this wall, which makes it possible to use the entire wall surface of the compression cylinder for cooling purposes.



       A similar arrangement can be made for the <B> pressure nozzle </B> compression cylinder, if desired, but ordinarily the pressure of the compressed fluid in this cylinder is too low to cause a corresponding increase in temperature of the fluid compressed, so that the normal flow of exhaust vapor through the aforementioned cooling jacket will be sufficiently effective for the intended cooling purposes.
