PCT No. PCT/CH84/00117 Sec. 371 Date Apr. 11, 1985 Sec. 102(e) Date Apr. 11, 1985 PCT Filed Jul. 26, 1984 PCT Pub. No. WO85/00871 PCT Pub. Date Feb. 28, 1985.The valve comprises a stationary part (1, 2), a mobile part (9) and a fluid-tight seal (15). This fluid-tight seal (15) consists of two portions (16, 17) axially separated by a cylindrical part (18). During filling, the connection (30) of the recharging tank moves the mobile part (9) downward against the action of a spring (10). A projection (31) works with the portion (16) of the seal to bring this latter downward. A ramp (32) guides the portion (17) of the seal to the connection (30). At the end of the path, this portion (17) is squeezed between the stationary part (1, 2) and the connection to assure a complete fluid-tightness of the filling passage (25) to the outside and a perfect separation of the two filling (25) and escape (21) passages. In the closed position of the valve, the upper part of the part (9) is engaged in the opening provided for the passage of the connection ( 30). |
