  • Cartridge for peristaltic pump with a flexible tube, and peristaltic pump fitted with such a cartridge
    Patent number: 5044902
    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.

  • Peristaltic pump
    Patent number: 4702679
    Abstract: A peristaltic pump having a deformable tube (11) forming the pump body, placed between rollers (15, 16) driven by friction from a central drive shaft (6), and located in an external casing (1) forming runways (13, 14) for the rollers, positioned on either side of a groove (10) in the tube housing. Each roller (15) engaging the tube (11) is rigid in its center section where it acts on the tube, but is elastically deformable at its ends which are running on the runways (13, 14).

  • Peristaltic pump and a tube for said pump
    Patent number: 4181476
    Abstract: The peristaltic pump has a rotor which is placed around a drive shaft and made up of planet-wheels supported by a planet-wheel carrier. The planet-wheels are maintained in contact with the drive shaft by means of a flexible tube forming a pump body which is passed at least once around the planet-wheels and the suction and discharge ends of which are approximately opposite to each other. Each interval between the planet-wheels is fitted with at least one inner rolling support for the tube.

  • Anti-bubble safety valve for a liquid-circuit
    Patent number: 4177808
    Abstract: The anti-bubble safety valve comprises a liquid-admission chamber which is partly delimited by a diaphragm in cooperating relation with a seating provided with an outlet pipe. Thus the liquid which is present within the chamber is directed into the diaphragm-seating interface and passed in laminar flow towards the outlet pipe. The chamber is provided with a passageway to the surrounding atmosphere for the discharge of any air bubble which may have been admitted.
