Claims

[Claims for Utility Model Registration] 1. A plunger-type pump for liquid feeding that has a pumping cylinder, a plunger whose one end side is inserted into the pumping cylinder in a fluid-tight manner, and a driving means for reciprocating the plunger, in which the plunger is driven. The means includes a control unit, a pulse motor whose rotational direction and rotation angle of the rotating shaft are controlled by a set pulse signal sent from the control unit, and means for converting the rotational motion of the rotating shaft into a linear reciprocating motion and transmitting it to the plunger. , the rotation of the pulse motor is alternately reversed at every predetermined rotation angle by sending setting pulses generated in the control section to the motor, and this rotational motion is converted into reciprocating motion and transmitted to the plunger, thereby causing the plunger to reciprocate and send. A pulse-controlled metering pump that dispenses liquid. 2. A utility model in which the means for converting rotational motion into linear reciprocating motion and transmitting it to the plunger is composed of a pinion attached to the rotating shaft of a pulse motor, and a rack that meshes with the pinion and is connected to the plunger. A pulse-controlled metering pump according to claim 1.
