Abstract
PURPOSE: To reduce a change of pulsation, eliminate the necessity for a pulsation reducer and miniaturize a device, by flowing an interrupted current in a solenoid coil, reciprocating two plungers in an opposite direction to each other and obtaining double cycles of delivery.
CONSTITUTION: When a current flows in an excitation coil 32, plungers 20, 21 compress a drive spring 26 to attract each other, close the first check valve 24 and open the second check valve 25. Accordingly liquid is delivered from a delivery port 23 through from a chamber B to a chamber C by the amount of a stroke of the first plunger 20. If the current in the excitation coil 32 is turned off, the plungers 20, 21 are press returned in a direction toward both outsides by the drive spring 26 to open the check valve 24 and close the check valve 25, then the liquid is sucked from a suction port 22 to the chamber B through a chamber A while the liquid in the chamber C is delivered from the delivery port 23 by the amount of a stroke of the second plunger 21. In this way, because the cycle of delivery is doubled, a change of pulsation can be reduced and a device can be miniaturized.
