DETAILED DESCRIPTION OF THE INVENTION

(13) The present invention describes an example of a sealing system (5) as the one shown in FIG. 1.

(14) In this figure, a cross-section view according to a longitudinal plane of a mounted sealing system (5) is shown. This system (5) comprises a main body (5.2), wherein the first surface (5.2.1) is the one located on the top of the mentioned figure, whereas the second surface (5.2.2) is the surface opposite the first surface (5.2.1) thus located in the bottom of the mentioned figure.

(15) As shown, the main body (5.2) comprises a through-hole which is mechanized in the center. Said through-hole houses the inflatable pad (5.1), being the ends of the mentioned inflatable pad (5.1) supported on the first surface (5.2.1) and on the second surface (5.2.2) respectively.

(16) The inflatable pad (5.1) is swelled inside the through-hole of the main body (5.2), thus occupying this free space. In this example, the inflatable pad (5.1) is made of latex such as the one present in a surgery glove.

(17) On top of the first surface (5.2.1) is located a first sealing portion (5.3). The first sealing portion (5.3) comprises tabs (5.3.1) which are supported on the first surface (5.2.1) of the main body (5.2). Additionally, said tabs (5.3.1) are fixed by means of the fixing member (5.5), which is an O-ring in this example.

(18) Analogously, the second sealing portion (5.4) is located on the second surface (5.2.2), also supported by means of tabs (5.4.1) and fixed by means of another O-ring (5.5).

(19) The mentioned through-hole of the main body (5.2) coincides with the through-hole of the first (5.3) and second (5.4) sealing portions.

(20) The main body (5.2) also comprises a unique cylindrical air distribution system (5.2.4) wherein the end is threaded. The air inlet (5.2.4.1) allows a flow of air to enter the sealing system (5) through the inner passage (5.2.3), exiting through the air outlets (5.2.4.2). Additionally, the perimeter recess (5.2.3.1) performed in the inner passage (5.2.3) of the main body (5.2) allows a better entry and distribution of the air flowing inside the inflatable pad (5.1).

(21) For obtaining the system (5) of FIG. 1, the inflatable pad (5.1) is fixed to the main body (5.2) by means of the O-rings (5.5), thus the ends of the inflatable pad (5.1) being supported on the first (5.2.1) and second (5.2.2) surfaces.

(22) After this, sealant (not shown) is added on the first (5.2.1) and second (5.2.2) surfaces of the main body (5.2), being those the mounting surfaces of said main body (5.2) as well as on the first (5.3) and second (5.4) sealing portions.

(23) Said first (5.3) and second (5.4) sealing portions are located with the added sealant (not shown) on the first (5.2.1) and second (5.2.2) surfaces of the main body (5.2), which also have sealant.

(24) In order to fix the totality of the parts, namely the inflatable pad (5.1), main body (5.2), first (5.3) and second (5.4) sealing portions and the at least O-rings together, screws are used as shown in FIG. 3, compressing the mentioned parts (5.1, 5.2, 5.3, 5.4).

(25) FIGS. 2A and 2B show the same sealing system (5) of FIG. 1, although now plan views of a transversal cross-section of the system (5) are shown.
