The hose pump has plates forming the first pressure members and limbs which form second pressure members and which are actuated by the plates. The limbs are fastened at one end to a base plate, in such a way that second portions formed at the other ends are parallel to and near one another and the surfaces, facing one another, of the middle portions are inclined towards one another, in order to move the limbs to-and-fro by means of the projections of the plate. By means of resilient elements which on the one hand rest against webs in the frame and on the other hand against the plate, the plate is held in contact with the drive. As a result of these measures, the efficiency and the effect of the hose pump can be improved. |
