Peristalitic pump
First Claim
1. A peristaltic pump comprising:
- a pump housing having a bottom thereof and a pump wall;
a rotor in the pump housing having a rotor wall;
a shaft for the rotor wherein the rotor is rotatable around the shaft;
a pump tube with an elastically deformable wall, which pump tube is arranged in the pump housing at the bottom thereof and is fitted into the pump housing with a portion which is curved in a part-circular configuration around the shaft of the rotor within the pump wall and at a radial spacing relative thereto;
wherein the cross-section of the pump tube is partially varied during the conveying operation by at least one component of the rotor which presses the pump tube in respect of cross-section against a support means; and
wherein the pump housing is dish-like and has in cross section a bottom with a bottom first portion which is formed approximately at a right angle on the pump wall and a bottom second portion which is inclined from the bottom first portion towards the rotor at an angle of inclination (w), and wherein said portions define a channel space in the pump housing in which the rotor wall engages.

Abstract
In a peristaltic pump comprising a pump tube with elastically deformable wall, which pump tube is arranged in a pump housing at the bottom thereof and is fitted into the pump housing with a portion which is curved in a part-circular configuration around a shaft of a rotor within the wall of the peristaltic pump and at a radial spacing relative thereto, the cross-section of the pump tube being partially varied during the conveying operation by at least one member of the rotor which presses the pump tube in respect of cross-section against a support means, with a reduction in the internal volume, the rotor is formed dish-like from a rotor end portion and a rotor wall and the latter is directed towards the bottom of the pump housing, the shaft of the rotor being fitted directly to the end portion thereof.
