<P>PROBLEM TO BE SOLVED: To replace a tube regardless of a stop position of a roller, and shorten the whole length of the tube when desiring to form a passage straight. <P>SOLUTION: This series rotor type tube pump 100 comprises a base 10, and a motor 20 fixed to it. Three drive shafts 21, 22, and 23 driven by the motor are rotatably arranged on the base 10. On the drive shafts, first, second, and third rotors 31, 32, and 33 each provided with a pair of rollers are installed. A movable housing 50 is provided with three cylindrical walls 51, 52, and 53 provided on the base so as to be slidable to separate from the rotor or approach it for holding an elastic tube 1 with the rollers. As the motor is rotated, the elastic tube is continuously crushed between the rollers and the cylindrical walls, and fluid in the tube is fed. <P>COPYRIGHT: (C)2007,JPO&INPIT |
