In addition, the rotary device (20) is pivotally connected between the front end wall (11) and the rear end wall (12) of the housing (10) by a pivot shaft (21). The pivot shaft (21) is inserted through the rear end wall (12) which is in communication with the air intake tube (15). The pivot shaft (21) comprises an axial blind hole (211) in communication with the passage (16) for the air that forms the intake tube (15), a through hole (212) radially extending, in communication with the valve connectors (25) (25 ') and the blind axial hole (211), two sealing rings (213) 5 each mounted around it on two opposite sides with respect to the radially extending through-hole (212) for holding the device body (22) and the pivot shaft (21) in an airtight state, and a sealing ring (214) mounted around it of the periphery of the shaft, close to the axial blind hole (211), for keeping the pivot shaft (21) and the air intake tube (15) in a sealing state at the 'air. The body (22) of the rotary device (20) is a tubular element (see Figures 5 and 7), having two through holes (221) arranged on two opposite sides of its middle part; the aforesaid pivot shaft (21) is inserted through the passage (16) for the air formed by the air intake tube (15) and through the two through-holes (221) of the body (22). ) for connecting the body (22) to the housing (10) pivotally between the front and rear end walls (11) (12), thereby allowing the air passage (16) to air intake (15) being in communication with the space inside the body (22) via the blind axial hole (211) and through the radially extending hole (212) ; said two valve connectors (25) (25 ') are mounted in the body (22) on an opposite upper and lower side with respect to the pivot shaft (21), each valve connector (25) ( 25 ') comprising - a housing member (26) (26'), a rubber seal (27) (27 '), a valve member (28) (28') and an end piece ( 29) (29 '). The housing member (26) (26 ') is a cylindrical member, comprising a shoulder (261) (261') at one end thereof, a through hole (262) (262 ') centrally located shoulder (261) (261 ') for insertion of the valve (1) (2) to be inflated (see Fig. 11 and Fig. 15), and at least two stop pins (263) ( 263 ') protruding from the opposite end thereof. The rubber seal (27) (27 ') is housed in the housing member (26) (26'), and is resiliently deformable to expand and reduce the hole axial (271) (271 ') arranged in it to retain the valves (1) (2) (the valve (1) shown in Figure 13 is a Schrader valve (American), the valve (2) shown in Figure 17 is a Presta valve (French)) intended to allow inflation. The valve member (28) (28 ') is mounted in the housing member (26) (26') adjacent to the stop pins (263) (263 '). The width of the outer side wall of the valve member (28) (28 ') is approximately equal to the width of the housing member (26) (26'). Further, the valve member (28) (28 ') comprises a plurality of notches (281) 10 (281') corresponding to the stop pins (263) (263 ') so that the stop pins (263) ) (263 ') can extend through the respective notches (281) (281'). In addition, the valve member (28) (28 ') locks the housing member (26) (26') so as to maintain the rubber seal (27) (27 ') in the element housing (26) (26 '). The length of the rubber seal (27) (27 ') is slightly larger than the depth of the housing member (26) (26') so that a gap (251) (251 ') ) is left between the valve member (28) (28 ') and the housing member (26) (26') when the rubber seal (27) (27 ') receives no pressure. Due to the presence of the space (251) (251 '), the valve member (28) (28') and the housing member (26) (26 ') can be forced to move. with respect to one another and elastically deforming the rubber seal (27) (27 '). The valve member (28) (28 ') includes a valve protrusion (282) (282') extending toward the rubber seal (27) (27 '). The valve protrusion (282) (282 ') is inserted into the axial hole (271) (271') of the rubber seal (27) (27 '). In addition, the valve protrusion (282) (282 ') is configured according to the configuration of the valve (1) (2) to be attached. The valve protrusion (282) of the valve member (28) of a valve connector (25) is in the form of a protruding rod, and has a groove on a lateral side thereof for the mounting of the valve member (28). a Schrader valve (American) (1). The valve protrusion (282 ') of the valve member (28') of the other valve connector (25 ') is in the form of a mounting cylinder of a Presta valve (French) (2). The valve member (28) (28 ') further comprises an arcuate elongated groove (283) (283') corresponding to the pivot shaft (21), a through hole (284) (284 ') centrally located the elongated arcuate groove (283) (283 ') extending through the valve projection (282) (282') and in communication with the through hole (212) of the pivot shaft (21), and a plurality of end walls (285) (285 ') provided adjacent to the arcuate elongated groove (283) (283') for biasing the stop rods (263 ') (263) of the valve member ( 28 ') (28) opposite. The housing member (26) (26 '), the rubber seal (27) (27') and the valve member (28) (28 ') are housed in the body (22). The end piece (29) (29 ') is fixedly mounted on an outer side of the body (22) to seal the housing member (26) (26'), the packing ( 27) (27 ') and the valve member (28) (28') in the body (22) in an airtight manner. In addition, the end piece (29) (29 ') comprises a through hole (291) (291') at its center. The shoulder (261) (262) of the housing member (26) (26 ') extends through the through hole (291) (291') outwardly of the end piece (29) (29 '). The housing member (26) (26 ') further comprises a convex outer end surface (264) (264'). The closure member (40) has an inner end concave surface (41) of shape corresponding to the outer end convex surface (264) (264 '), and an annular seal ring (42) located at level of said concave inner end surface (41) for surrounding the through hole (262) (262 ') of the shoulder (261) (261') of the housing member (26) (26 '). The housing (10) further comprises a receiving chamber (131) defined in the upper end wall (13) thereof. The closure member (40) is housed in said receiving chamber (131) and is adapted to move axially back and forth in said receiving chamber (131). The lever (30) is pivotally connected to the upper end wall (13) by a pivot axis (31).
    [0009] When the lever (30) is biased from the release position to the pressure position, it forces the closure member (40) to move toward the housing member (26 ') and thereby provide additional sealing of said housing member (26 '). The two housing members (26) (26 ') each have a sealing ring (265') respectively mounted thereon so as to be able to keep the housing members (26) airtight ( 26 ') and said body (22). Figures 11 to 14 illustrate a rotary type valve coupling connected to a Schrader valve (US) (1). As illustrated in FIGS. 11 and 12, the Schrader valve (American) (1) is inserted into the valve connector (25). At this time, the lever (30) is disposed in the release position; the closure member (40) receives no pressure and does not press on the valve connector (25 '); the space (251) (251 ') between the housing member (26) (26') and the valve member (28) (28 ') is maintained at the initial setting value; as shown in Fig. 12, the stop pins (263 ') of the housing member (26') which are disposed above the pivot shaft (21) abut against the end walls ( 285) of the valve member (28) which are arranged below the pivot shaft (21); as shown in Fig. 13, the lever (30), when raised, will move the closure member (40) down a predetermined distance so as to move the housing member (26 ') of the valve connector (25 ') down, stop rods (263') of housing member (26 ') urging valve member (28) downwardly (valve member (28') ) being prevented from being moved downwards by the pivot shaft (21)), the rubber seals (27) (27 ') being consequently simultaneously and elastically compressed in the direction of their widening reducing the respective gaps (251) (251 ') and causing the formation of a predetermined gap (252) between the two valve portions (28) (28') (see Figures 13 and 14). When enlarged, the rubber seal (27) seals the Schrader valve (US) (1), the closure member (40) sealingly sealing the through hole ( 262 ') of the housing member (26') so as to allow the air of the air intake tube (15) to pass through the axial blind hole (211), the through hole (212). and the through hole (284) into the Schrader valve (US) (1).
    [0010] When switching between the valve connectors, the lever (30) is pivoted to the release position, the rotating device (20) then being rotated to exchange the position of the valve connector (25) (25 ') as shown FIGS. 15 to 18 illustrate the rotary type valve coupling connected to a Presta valve (French) (2). The principle and operation of this coupling are the same as for the use of the Schrader valve (American) (1). Therefore, no more detailed description on this point is necessary. Figures 19 and 20 illustrate a rotary type valve coupling according to a second embodiment of the present invention. This second embodiment is substantially similar to the first embodiment mentioned above, and the same references designate the same structural elements. This second embodiment also comprises a housing (10), a rotary device (50), a lever (30), and a closure member (40). The main difference between this second embodiment and the first aforementioned embodiment is that the rotary device (20) of the first embodiment comprises a pivot shaft (21); the rotary device (50) of this second embodiment eliminates said pivot shaft, and comprises two protruding rods (521) (522) on two of the opposite lateral sides of the body (52) of this device, each of which is mounted so that pivotable between the front end wall and the rear end wall (11) (12) to substitute for the aforementioned pivot shaft (21); the protruding rod (522) which is pivotally connected to the rear end wall (12) comprises a through hole (523) forming a communication between the air passage (16) of the air intake tube (15) and the space inside the rotary device (50); in addition, a sealing ring (524) is mounted around the projecting rod (522). Since this second embodiment makes it possible to eliminate said pivot shaft (21) in order to prevent impeding the movement of the valve connectors (55) (55 ') of the rotary device (50), the two parts of valve (28) (28 ') in said first embodiment may be made to form only one valve member (58) for use in this second embodiment; the abutment rods (263) (263 ') mentioned above are, in this second embodiment, removed from the two housing elements (56) (56') of the rotary device (50); the length of the two rubber packings (57) (57 ') is also greater than the depth of the two box members (56) (56'); therefore, when no pressure is applied to the rotary device (50), a gap (551) (551 ') is always maintained between each housing member (56) (56') and the valve member (58). ); when the lever (30) is moved from the release position to the pressure position (see Fig. 21 and Fig. 22), the lever (30) forces the closure member (40) to move the box member (56 ') downward and further compressing, by elastically expanding, the rubber seal (57'), moving the valve member (58) downwardly against the seal. sealing (57) rubber, causing an elastic deformation of the rubber seal (57) which thus ensures the sealing of the valve Schrader (US) (1) (see Figure 22) or the valve Presta (French) (2) (see Figure 24); at this moment, the two spaces (551) (551 ') have disappeared. The rotary device (50) includes a barrel-shaped body (52) having two protruding rods (521) (522) on two of its opposite lateral sides. A projecting rod (522) includes a through hole (523) in communication with the interior space of the body (52) and with the atmosphere; a sealing ring (524) is mounted around the projecting rod (522); a valve member (58) is housed in the body (52) and includes an annular air passage (581) defined between the inner periphery of the body (52) and an outer perimeter of the valve member ( 58), a through-hole (583) at the periphery thereof communicating with the air passage (581), two valve projections (582) (582 ') each extending from two opposite sides thereof and being configured to accommodate different valves (1) (2), and a through hole (584) provided between the two valve protrusions (582) (582 ') in communication with the through hole (583); two rubber pads (57) (57 ') are disposed on two opposite sides of the valve member (58) around the valve projections (582) (582'); two housing members (56) (56 ') are mounted around the rubber seals (57) (57') and define with the valve member (58) a respective predetermined space (551) (551 ') and include a through-hole (562) (562 ') at a respective outer end surface (561) (561') therein; two end pieces (59) (59 ') are respectively fixedly mounted at two opposite ends of the body (52) for sealingly sealing the two housing members (56) (56'), the two packings of sealing (57) (57 ') of rubber and a valve member (58) in the body (52), each end piece having a through hole (591) (591') to allow the outer end surfaces ( 561) (561 ') of said two housing members (56) (56') extending outwardly from the respective end pieces (59) (59 ') through the through-holes (591) (591') respective of these; two sealing rings (563) (563 ') are respectively mounted around said two housing members (56) (56').
