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.

Description
- a
cylindric body 1, linked to thehandle 2; - a top tapering obtained with the opposite
inclined planes body 1 into a laminar shape; - a
first curve 5 of about 45°; - a
second curve 6 in a sense opposite to the precedent one, obtained on the top of the tapering, for obtaining a means that may penetrate between the gasket G and the perimetral cavity IP of an oleo-hydraulic or pneumatic cylinder C, so that, once said gasket has been bared of, and due to its elasticity, it may be taken off making it slide along saidcurve 5.
Claims (1)
- A utensil for the disassembly and the assembly of oleodynamic and air gaskets, the utensil comprising:a handle (2);a cylindric body (1), linked to the handle (2);a tapering near the tip of the body remote from the handle, obtained with oppositely inclined planes (3, 4) which transform the cylindric structure of the body (1) into a laminar shape at the tip of the body;a first curve (5) defined by a bent in the tapered body portion over about 45°;a second curve (6) defined by a bent between the first curve (5) and the tip in a sense opposite to the first curve (5), the bent defining the second curve being smaller than the bent defining the first curve (5) and being obtained on the top of the tapering, for obtaining a means that may penetrate between the gasket (G) and the perimetral cavity (IP) of an oleo-hydraulic or pneumatic cylinder (C), so that, once said gasket has been bared of, and due to its elasticity, it may be taken off making it slide along said first curve (5).
