A process and device for the extraction of sealed cartridges

摘要

The device comprises a member (7) for injecting water, a gripping ring (9) with two gripping ramps (10) coaxial with the water-injection member, a cartridge-holder support (15) with two diametrically opposed gripping tabs (17) provided in order to engage on the gripping ramps of the gripping ring and coaxially with the water-injection member, an annular piece (8) with an inner housing whose shape substantially matches the outer shape of the cartridge to be extracted and a cartridge holder (11) arranged in the cartridge-holder support and comprising projecting elements (13) on a flow grid (12), the lower part of the annular piece interacting with the perimeter of the cartridge holder in order to ensure holding of the cartridge and leaktightness during extraction.
