Abstract: This container includes a neck (26), the free end of which is equipped with an orifice for outflow of the pressurized fluid contained in the container, closed off by a perforatable cover (30) in order to release the pressurized fluid. The pressurized-fluid delivery assembly comprises the container and an element (36) for connecting the neck (26) to pressurized-fluid supply pipe (37) of a hydraulic circuit, these being equipped with elements (40) for piercing the cover which are able to be actuated after connection of the neck to the supply pipe (37). This assembly makes it possible to supply, for example, a brake-fluid reservoir of a hydraulic pressurized-brake-fluid brake circuit so as to bleed this circuit.

Abstract: This sealing device for a cylindrical metal pack having a total opening, of the type comprising a recipient and a pressed-out cover and in which the inner peripheral surface of the opening of the recipient, which is devoid of an inner radial flange, cooperates directly with the outer cylindrical surface of the cover, comprises at least one partly O-section sealing element (11, 12) of a copolymer resin adhered in at least one cylindrical groove (9, 10) provided in the region of the recipient and/or the cover in which occurs a rubbing between the cooperating parts of the inner wall (8) of the opening of the recipient and of the outer peripheral wall of the cover when the cover (5) is placed in position and removed.
