  • Patent number: 8491285
    Abstract: The invention concerns a hose cartridge for a peristaltic pump comprising a cartridge housing, comprising a flexible pump hose segment extending through the cartridge housing, wherein both ends of the pump hose segment are fixed in the cartridge housing by a first fixing member and a second fixing member, wherein the first fixing member and the second fixing member are arranged in the area of a first front face of the cartridge housing, and wherein the cartridge housing includes a recess for the engagement of a roller wheel of the pump in the interior of the cartridge housing. It is characterized by that the pump hose segment extends in the hose cartridge along a circular segment (K) spanning an angle of at least 90°, when the hose cartridge is not inserted into the pump.

  • Patent number: 7287968
    Abstract: A peristaltic hose pump comprising a roller wheel, which can rotate about a roller wheel axis and which has rollers that are mounted on the roller wheel. The rollers roll along a circular path having a certain radius with respect to the roller wheel axis. The peristaltic hose pump also comprises a pressure arched element with a supporting surface, whereby the supporting surface extends along a circular path having a certain radius around the rotation axis of the roller wheel. In addition, a flexible hose can be inserted between the supporting surface and the rollers of the roller wheel.

  • Patent number: 7004130
    Abstract: A camshaft adjuster for an internal combustion engine having hydraulic medium guides. The adjuster can include a setting unit that can be controlled by a control unit using these guides in the adjuster, wherein the setting unit is for adjusting an angle of a camshaft. This setting unit has an inner body coupled to the camshaft so as to rotate with it, and an outer body that is mounted to rotate relative to the camshaft via a drive connection which runs from a crankshaft to the camshaft. The camshaft has at least one insert part permanently inserted camshaft wherein these two components together form at least one hydraulic medium guide at least in partial regions over its axial length. This design is to create a camshaft adjuster which is in interaction with a camshaft having an insert part so that there is a simple and reliable supply of hydraulic medium to the camshaft adjuster and in particular to its control device.

  • Publication number: 20040037724
    Abstract: The invention relates to a peristaltic hose pump comprising a roller wheel (1), which can rotate about a roller wheel axis D and which has rollers (2) that are mounted on the roller wheel (1). The rollers (2) roll away on a circular path having a radius R1 with regard to the roller wheel rotation axis D. The peristaltic hose pump also comprises a pressure arched element (3) with a supporting surface (4), whereby the supporting surface (4) extends along a circular path having a radius R2 around the rotation axis D of the roller wheel (1). In addition, a flexible hose (19) can be placed between the supporting surface (4) and the rollers (2) of the roller wheel (1).

  • Patent number: 6468059
    Abstract: A hose cassette (1), for a peristaltic pump (2), includes a cassette housing (3) and a flexible hose (4) extending through cassette housing (3). The hose (4) is guided in the cassette housing (3) along a circular segment. The cassette housing (3) has a cutout (5) for the engagement of a roller wheel (6) of a peristaltic to pump (2) into the interior of said circular segment. The hose cassette has connection elements (7), (8) for connecting the cassette housing (3) to the peristaltic pump (2). At least one hose leg (9), (10) to be connected to the circular segment is displaceably held between a mounting position and an operating position in the cassette housing (3).
