The valve arrangement comprises a valve plate (1) which is connected to the pressure vessel and has a central passage channel (5), in which a valve body (9) is inserted. By deformation in the axial direction, the valve body (9) is raised from a sealing surface (8) of the channel (5) and a passage is created from the interior of the pressure vessel via an outlet borehole (16) into the atmosphere. A filling opening (17) is provided for filling the pressure vessel, which filling opening is fitted with a swivellable flap (18). This flap (18) is moulded integrally onto the valve body (9). When a medium under high pressure is fed through the filling borehole (30) of a filling attachment (28), the flap (18) swivels outwards and exposes the filling opening (17), so that the medium introduced can flow into the pressure vessel, essentially without flowing through the calibrated outlet borehole (16) in the valve body (9) since the clear cross-section of the filling opening (17) is substantially larger than that of the outlet borehole (16). When the filling operation has been completed, the flap (18) automatically closes the filling opening (17), so that, when the medium stored in the pressure vessel is removed, said medium can only emerge through the outlet borehole (16) in a metered manner. Thus, for example, an aerosol can can be filled in a very short time without the calibrated outlet borehole being subjected to the risk of damage due to the high filling pressures. <IMAGE>
