Abstract
PURPOSE:To eliminate the suction and delivery valves by mounting a driving device comprised of a cylindrical cam on a plunger to be fitted with a cylinder having the suction and delivery ports in the side wall face and used particularly for the chemicals determination pump thereby rotating the plunger synchronously with the reciprocal motion. CONSTITUTION:A suction port 3 and a delivery port 4 are made at the predetermined position on the side of a cylinder 1. A notch 6 is made in the top of the plunger 5 and its lower end is secured through a pin 10 to a cylindrical cam 9. A groove 14 of desired curve to stop a pin 13 is formed on the circumference of said cam 10. With such structure when the shafts 12A, 12B are rotated by a motor 11, the piston 5 will reciprocate axially at the same time with the rotation, thereby the suction port 3 and the delivery 4 will open/close periodically by the side of the piston 5 thus to suck/deliver the chemicals periodically.
