<p>A ripple regulating system is disposed in a liquid supply system for minimizing pressure ripples generated by a pump employed in the liquid supply system. The ripple regulating system includes a pressure chamber of which one wall comprises a bellowphragm. A spring is secured to the bellowphragm to apply a predetermined pressure to the pressure chamber. A detection system is associated with the pressure chamber for detecting a balance pressure variation. When the balance pressure becomes higher than the preselected level, an adjusting system is operated to increase the depression pressure generated by the spring, thereby maintaining the constant flow rate supply.</p> |
