  "DISPOSITIF PERMETTANT D'AUGMENTER L'ADHERENCE DES FISTONS 
GARNIS DE CUIR   EMBOUTI   
La présente demande de brevet a pour objet un dispositif permettant d'augmenter l'adhérence des   cuits   emboutis garnis- sant les pistons des corps de pompes, compresseurs, ou autres engins à piston. 



   A cet effet le piéton sur lequel repose le cuir embouti est pourvu d'une gorge dans laquelle est disposé un cercle de piston du type bien   connu,,dont   la faoe extérieure presse sur le face interne du cuir embouti, ce qui oblige celui-ci à garder le contact avec l'alésage du cylindre dans lequel il se meut.En outre le piston comporte quatre douilles radiales, ou davantage, dans lesquelles à la naissance du fond de la gor ge logeant le cercle de piston, sont forés des trous logeant des ressorts à boudin,qui par leur extrémité libre agissent sur la face intérieure du cercle de piston, pour augmenter 1' 

 <Desc/Clms Page number 2> 

 adhérence du cecel de piston sur le cuir embouti et éventuelle- ment compenser l'usure du. cuir. 



   Afin de mieux faire ressortir l'exposé ci-dessu les des- sins annexés représentent! 
La fig.1 une coupe dans un cylindre muni des pistons gar- nis de cuir embouti avec le dispositif conformément à l'objet de l'invention . 



   La   fige?.   une vue de face du cylindre ouvert montrant le piston avec ses saillies ou douilles radiales. 



   La fig.3 une coupe en élévation dans une variante de cons-   truation     ,d'un   piston de pompe aspirante. 



   En se reportant aux fig.ci-dessu le cuir embouti garnit extérieurement un corps de piston 2 muni d'une gorge 6 dans laquelle est logé le cercle de piston 4. 



   Le corps du piston 2 est pourvu de douilles 3 munies de perforations dans lesquelles sont placés des ressorts tels que 5 qui par l'une de leurs extrémités appuie sur le fond de la perforation et par l'autre sur la face interne tu car- ale piston 4 
Dans l'exemple de la   fig.l   la pompe ou compresseur étant à double effet on a disposé dos à dos deux pistons tels que 2 reliés par la tige commune 8. 



   DAns la   fig.3   on a représenté une variante constructive dans laquelle le fond du piston 2 porte le clapet d'aspiration, une bride 9 faisant corps avec le piston 2 est destinée au raccordement à la tige 8 
Dans cette variante on retrouve teus les éléments carac t éristiques énoncés au suet de la   fig.l,,   
Il va de soi que l'on peut apporter d'autres détails de construction dans l'exécution de l'objet de l'invention .sans que pour cela s'écarter des limites de l'invention comme expo se ci-dessus. 



   Ainsi par exemple à la place des ressorts radiaux 5 on pourrait disposer des ressorts à lame logés dans la gorge 6 qui contribueraient également par leur forme à l'écartement   @

 du segment 4. 



   De même, l'usage ou la destination de la pompe ou compres- seur peut être quelconque, ainsi que le nombre et la disposition des cylindres renfermant les pistons garnis de segments avec ressorts radiaux , et cuirs emboutis comme décrit précédemment.

  "DEVICE ALLOWING TO INCREASE THE ADHESION OF FISTONS
EMBALLED LEATHER TRIM
The subject of the present patent application is a device which makes it possible to increase the adhesion of the stamped plates lining the pistons of the bodies of pumps, compressors, or other piston devices.



   For this purpose, the pedestrian on which the crimped leather rests is provided with a groove in which is disposed a piston ring of the well-known type, the outer faoe of which presses on the internal face of the crimped leather, which forces the latter to maintain contact with the bore of the cylinder in which it moves. In addition the piston has four radial bushings, or more, in which at the beginning of the bottom of the groove housing the piston ring, holes are drilled housing coil springs, which by their free end act on the inner face of the piston ring, to increase 1 '

 adhesion of the piston cecel to the crimped leather and possibly compensate for the wear of the. leather.



   In order to better highlight the above description, the attached drawings represent!
FIG. 1 a section through a cylinder provided with the pistons lined with crimped leather with the device according to the object of the invention.



   Freeze ?. a front view of the open cylinder showing the piston with its radial projections or bushings.



   FIG. 3 is a sectional elevation in an alternative construction of a suction pump piston.



   Referring to the figures above, the crimped leather adorns a piston body 2 on the outside provided with a groove 6 in which the piston ring 4 is housed.



   The body of the piston 2 is provided with bushings 3 provided with perforations in which springs such as 5 are placed, which by one of their ends presses on the bottom of the perforation and by the other on the internal face of the hole. piston 4
In the example of fig.l, the pump or compressor being double-acting, two pistons such as 2 are placed back to back, connected by the common rod 8.



   In fig. 3 there is shown a constructive variant in which the bottom of the piston 2 carries the suction valve, a flange 9 forming part of the piston 2 is intended for connection to the rod 8
In this variant we find all the characteristic elements stated in the subject of fig.l ,,
It goes without saying that other constructional details can be provided in the execution of the object of the invention without departing from the limits of the invention as explained above.



   Thus, for example, instead of the radial springs 5, leaf springs housed in the groove 6 could be arranged which would also contribute by their shape to the spacing @

 of segment 4.



   Likewise, the use or destination of the pump or compressor can be arbitrary, as well as the number and the arrangement of the cylinders containing the pistons furnished with rings with radial springs, and pressed leathers as described above.

REVENDICATION Dispositif permettant d'augmenter l'adhérence des pistons garnis de cuir emboutilcaractérisé en ce que le piston recouvert par le cuir embcuti comporte une gorge ou rainure circulaire dans laquelle est engagé un segment de piston dont la face interne reçoit la poussée de ressorts logés ou non dans les perforations de douilles du piston, disposées radialement ,tandis que la face externe du dit segment s'applique sur la face interne du cuir embouti de manière à ce que celui-ci adhère intimement sur la fa- ce interne du corps cylindrique dans lequel il se meut . CLAIM Device making it possible to increase the adhesion of the pistons furnished with embroidery leather, characterized in that the piston covered by embcuti leather has a groove or circular groove in which is engaged a piston ring, the inner face of which receives the thrust of springs, whether or not they are housed in the bushings of the piston, arranged radially, while the outer face of said segment is applied to the inner face of the crimped leather so that the latter adheres intimately to the inner face of the cylindrical body in which he moves. RESUME Un segment de piston est disposé entre la face interne du cuir embouti et le corps du piston proprement dit, desrcorts disposés radialement ou dans la gorge ou rainure circulaire lo- geant le segment ,contribuant avantageusement à l'adhérence du cuir embouti sur la face du cylindre. ABSTRACT A piston ring is disposed between the inner face of the crimped leather and the body of the piston itself, with reinforcements disposed radially or in the groove or circular groove housing the ring, advantageously contributing to the adhesion of the crimped leather to the face of the piston. cylinder.
