Definitions
- the present invention concerns a new utensil, specific for the disassembly and assembly of oleodynamic or air gaskets, like those applied onto oleo-hydraulic and pneumatic cylinders.
- a utensil for removing O-rings and backup rings from perimetral cavaties of cylinders is known from US-A-481320.
- the body of this utensil is provided with planes defining a laminar shape at the tip of the body.
- two oppositely curved sections are provided which define a prying section that may penetrate between the O-ring respectively the backup ring and the perimetral cavity.
- Figure 1 shows an axonometric view of a specific utensil for the disassembly and assembly of oleodynamic and air gaskets.
- Figure 2 shows a vertical section of the new utensil according to the present invention.
- Figure 3 shows a scheme of the functioning and the way of using the utensil according to the present invention.
- the utensil according to the present invention performs above described phases in opposite sense.

Claims (1)
- Outil pour le démontage et le montage de garnitures hydrauliques et à air comprenant:un manche (2);un corps cylindrique (1), solidaire du manche (2);un rétrécissement, vers le sommet du corps opposé au manche, obtenu avec des plans inclinés opposés (3, 4) qui transforment la structure cylindrique du corps (1) en une forme laminaire au sommet du corps;un premier cintrage (5) défini par une inclinaison d'environ 45° de la portion du corps rétréci;un second cintrage (6), défini par une inclinaison entre le premier cintrage (5) et le sommet, en sens opposé au premier cintrage (5), l'inclinaison définissant le second cintrage étant inférieure à l'inclinaison définissant le premier cintrage (5) et étant obtenue sur le sommet du rétrécissement, pour former un moyen de pénétration entre la garniture (G) et l'encaissement périmétral (IP) d'un cylindre (C) hydraulique ou pneumatique, de manière à ce que, une fois la dite garniture déchaussée, par son élasticité, elle puisse être extraite en la faisant glisser le long du dit premier cintrage (5).
