Abstract
The cartridge (7) is comprised of a housing (8) which comprises, in the vicinity of each of its ends, a cylindrical raceway (16, 17) against which are capable of applying and rolling bevel gears (9) which crush the flexible tube (2) located between both raceways. The bevel gears (9) are tubular and freely mounted inside the housing (8), within the concavity of the flexible tube, this housing comprising, at least on one side, a central opening (13) with a diameter large enough to enable the driving of the bevel gears either directly from a rotary disc (5) provided with planet gears (22) capable of engaging into the tubular bevel gears or from a shaft internally engaged between the tubular bevel gears.
