Title: Apparatus for absorbing pulsation of pump
Inventor: IDEI MICHIO
IPC: F04B11/00
Filed: 1981-03-23
Abstract: PURPOSE:To absorb pulsation of a pump, by communicating two pressure chambers separated by a diapharagm respectively to the suction side and the discharge side of the pump. CONSTITUTION:When a pump 1 is set into operation and suction and discharge of fuel is caused by reciprocating motion of a plunger, a diaphragm 12 repeats expansion and contraction to a suction-side pressure chamber 13 synchronously with the motion of the diaphragm 12, so that pulsation of the pump on both of the suction and discharge sides of the same is absorbed. Here, since the diaphragm 12 acts like a pump, flow characteristics of the pump can be improved. That is, when pressure at the discharge side of the pump is raised due to discharging of fuel from the pump, the diaphragm 12 is expanded toward the pressure chamber 13 and levels the discharge-side pressure by absorbing the pressure rise. Although pressure drop is caused on the suction side of the pump at the time, expansion of the diaphragm 12 results in application of pressure to the suction side of the pump, so that the pressure drop on the suction side of the pump can be compensated by the movement of the diaphragm 12.
