    • PURPOSE: To control flow rate with a simple structure by adjusting a movement period with an electric control circuit corresponding to a pulse from a pulse generator and adjusting amplitude corresponding to a reference value from amplitude adjusting means and a signal from a transmission member displacement detecting sensor of a variable stroke pump. CONSTITUTION: A control unit 17 comprises a potentiometer 20 for setting a stroke reference value of the variable stroke pump connection rod 8; and a pulse generator 28 for adjusting a motion period. Further, when an initial pulse 27a from the pulse generator 28 is inputted into a logic circuit 24, a LED 14 is turned on to positively rotate a motor 1, and rotation displacement of a crankshaft 4 is detected by an encoder 23. When an analog amount via a converter 22 is in conformity with a voltage of the potentiometer 20, the logic circuit 24 turns the LED 14 on and turns a LED 15 off so as to inversely rotate the motor 1. This operation is repeated to control throughput. When the control unit is connected to an external apparatus via a connector 30, the period can be varied by pulse 27b.
