ABSTRACT:
A hose pump comprising a number of movable pressure elements composed of a first pressure device and a second pressure device. The first pressure device is constituted by an element which is movable to-and-fro with respect to a counter pressure surface and the second pressure device contains elements movable to-and-fro with respect to a hose. The pressure devices are arranged next to one another and are driven by a common drive, in order to rhythmically compress the hose within two neighboring regions. The drive comprises cam discs structured to correspond to the number of pressure elements, the apex of crown points of the cam discs being mutually offset with respect to one another, in order to rhythmically compress the hose which is placed in the hose pump, and thus, to convey the medium which is to be pumped.
