Peristaltic pump

Abstract

Abstract PURPOSE:To enable to feed liquid rapidly in either direction of a resilient tube, by operating an actuating section after uncoupling a clutch from a motor shaft by means of a clutch control rod. CONSTITUTION:When a clutch control rod 22 is shifted to the left in the drawing by a knob 23, a clutch 16 is uncoupled from a motor shaft 19. In this state, if an actuating section 20 is turned in a desired direction at a speed higher than the speed of rotation of a motor 15, the clutch 16 is turned independently of the motor shaft 19. Therefore, rotation of the section 20 is transmitted from a drive shaft 1 to a turning plate 2 and rollers 4 are turned around the drive shaft 1, so that depression and releasing of a resilient tube 10 are caused independently of rotation of the motor 15. Resultantly, the resilient tube 10 can be filled with liquid by discharging liquid at a higher speed than that determined by the motor 15.
