Abstract

PURPOSE: To improve durability of a pump, by pressurizing the squeezed part of a resilient tube with squeezing rollers before communication at the delivery side.
CONSTITUTION: Squeezing rollers 9, 13 are rotatably supported to a driving shaft 5 supported to the center 0 of a cylindrical drum 1 to which a resilient tube 4 is fitted in a U-shaped state, and driving rollers 22, 23, 26, 27 are supported to fixed cam members 18, 19 eccentrically secured from the center 0. Then one roller 13 of the squeezing rollers is situated in a pressing start point P of the resilient tube 4 by the driving shaft 5 and the other squeezing roller 9 is further rotated from a position in an approaching state to a pressing end point Q. As a result on the basis of the orbital angular velocity difference between the preceding squeezing roller 9 and the following squeezing roller 13, a squeezed part A of the resilient tube 4 is pressurized, and pressure in the squeezed part A and delivery side B become equal when the squeezing roller 9 is moved to the pressing end point Q, thus a reverse current from the delivery side B can be eliminated.
