Definitions

  • the invention relates to a hose pump comprising a housing with a circularly curving wall surface and a rotatable support means carrying a plurality of rollers, where said support means is adapted to press said rollers against the circular wall surface and to cause said rollers to propel a fluid through a hose, a length of said hose being arranged between the wall surface and the rollers, and where the support means of the rollers is connected to said rollers by means of a displacing mechanism adapted to move the rollers into a squeezing engagement with the hose length in question when the support means is turned in the fluid propelling direction and to pull said rollers out of said engagement when said support means is turned in the opposite direction.
  • Hose pumps of the above type are known, whereby a pump medium is propelled through the hose by said hose being influenced in a peristaltic manner by a rotatable support means with rollers which press the hose against a circular wall surface within a hose length arranged against said wall surface.
  • a rotatable support means with rollers which press the hose against a circular wall surface within a hose length arranged against said wall surface.
  • US-PS No.4,070,725 discloses a pump comprising a housing.
  • a plurality of rollers are provided inside the housing, said rollers being supported by a support means and being guided by means of a guide member.
  • the support means is forced to rotate by means of a handle.
  • the support means is formed by two complemental sections receiving the rollers 14 therebetween, said rollers comprising their respective journals projecting from and being received in their respective helical slots in each section.
  • the frictional engagement with a hose between the rollers and the inner side of the housing has the effect that the rollers are pressed radially outward when the support means is rotated by means of a handle. As a result, the hose length is compressed.
  • the object of the invention is to provide a relatively compact hose pump which allows an easy mounting of the hose in question and an easy activation of the pump.
  • a hose pump is obtained which renders it possible to cause the rollers to enter the squeezing engagement with the hose length in question while the pumping effect is initiated by a rotation of the support means.
  • the easy disengagement of the rollers and the hose by a rotation in the opposite direction has the effect that it is easy to position the hose length along the circularly curving surface inside the housing, and the pumping effect is easily initiated by a rotation of the support means in the opposite direction.
  • the rotatable support means may be pivotally joumalled on a fixed shaft centrally arranged inside the housing and the displacing mechanism may be a crank mechanism, where the support means forms the crank, and where each roller is rotatably arranged on a roller shaft which in turn is pivotally j ournalled on a connecting rod and engages a guideway, whereby a first stopping means is provided for retaining the rollers in a position in which each roller is in the squeezing engagement with the hose length in question when the support means is rotated, as well as a second stopping means for retaining said rollers in a position in which the rollers have disengaged the hose length in question when the support means is rotated in the opposite direction.
  • the rollers disengage and engage the hose length in a reliable and simple manner by means of a crank mechanism, where the crank carries out the crank function during a portion of a complete rotation and subjects the roller shaft of the rollers to a stroke through the connecting rod.
  • the latter stroke extends between two positions which are spaced apart when seen in the radial direction in response to the shape and length of the guideway.
  • the above stopping means ensure a limitation of the rotation of the support means relative to the rollers as well as cause the rollers to follow during a continued rotation of the support means in the position in which each roller has entered the squeezing engagement with the hose length in question. Although the pumping effect is briefly stopped, the rollers remain in the closing engagement with the hose.
  • the guideway may according to the invention advantageously be shaped in a guideway disc loosely arranged coaxially to the support means, and the stopping means may be fixedly connected to the guideway disc with the result that the function of the crank mechanism is ensured in a particularly simple manner.
  • the stopping means may according to the invention be shaped as respective ends of a plurality of guide slits, a pin engaging each of these slits and being fixedly connected to the support means.
  • a uniform distribution of the load on the bearings forming part of the hose pump is ensured in a simple manner by a guideway disc being provided with associated guide- way and stopping means at each end of the roller shafts.
  • the uniform distribution of the load is further enhanced by a connecting rod being provided at each end of the roller shafts.
  • the guideway discs may advantageously be interconnected.
  • the support means may according to the invention be fixedly connected to a handle by means of a plurality of pins extending parallel to the axis of rotation of the support means and engaging their respective sets of associated guide slits in the two guideway discs.
  • the handle may be associated with locking means for releasably locking the rollers in the engagement with the hose length when said en- gagement has been initiated with the result that a release cannot erroneously be initiated of the engagement of the rollers with said hose length.
  • the support means may according to the invention be displaceable as a unit together with the rollers, the displacement mechanism thereof and the guideway discs between abutments on the shaft arranged centrally in the housing.
  • the hose length in question can be arranged around the rollers in a particularly simple manner.
