Peristaltic rotation pump with exact, especially mechanically linear dosage
First Claim
1. A peristaltic rotation pump with exact, especially mechanically linear dosing, comprises:
- a pump segment placed on a working path, is said path being adjacent to an elevated circular supporting occlusal path and a rotor with pressure rollers, characteristic by the fact, said pump segment extending along the working path, both ends of said pump segment leaning against a supporting surface outside the working path, the working path being transversally grooved at the place of contact with the compressed pump segment and being adjacent within all its length to an elevated circular supporting occlusal path on which at least two pressure rollers roll, the rollers being freely sliding mounted with their outside surface in a hollow slide mounting of the pressure blocks placed flexibly in the hollow arms of at least double-arm rotor, the rotor being connected to a shaft of the step motor, while the supporting occlusal path is elevated in the direction to the rotor rotation center above the transversally grooved working path comprised of the lead-in path, occlusal path and releasing path.

Abstract
The peristaltic rotation pump includes the pump segment extending along the working path, which is transversely grooved at the place of contact with the compressed pump segment, and is adjacent along all its length to an elevated circular supporting occlusal path, for rolling of pressure rollers. The working path includes a lead-in path, occlusal path and releasing path. Mechanical linearity of dosing is ensured by a circular occlusal path and the nearly circular releasing path, adjacent along all its length to the elevated supporting occlusal path for rolling of at least three pressure rollers. The angle length of the releasing path corresponding to the distance from the point of the beginning of releasing the pump segment to the point of complete release of the pump segment by the pressure roller is identical with that of the occlusal path.
