ABSTRACT:
A liquid supply system comprising a plunger pump and a ripple regulating system. The ripple regulating system includes a ripple regulator having a pressure chamber of which one wall is implemented with a bellowphragm for varying the volume of the pressure chamber. A solenoid mechanism is associated with the bellowphragm to shift the bellowphragm. The solenoid mechanism is activated in synchronization with the drive of the plunger pump, thereby minimizing the pressure ripples generated by the plunger pump.
