Abstract
PURPOSE:To cancel the pulsating pressure in pipe water by generating a pulsating pressure of opposite phase to the pulsating pressure contained in pipe water in the airtight chamber of an interference part provided on the way of a water pipe. CONSTITUTION:When the runner of a pump is rotated, water is supplied to a meeting pipe through a water pipe 3. The pipe water is given pressure-pulsating waves of a proportional frequency to the rotational frequency of a motor by the pump. When a pulsating-pressure generating unit 7 is operated, the pressurized water discharged from a pump 84 is alternately supplied to the upper and the lower part of an actuator 75 by the control of a pilot valve 8, and a piston 71 linked with the actuator 75 is operated to generate pressure-pulsating waves in an airtight chamber 43. The number of projections 52 of a cam 51 to operate the pilot valve 8 at this stage is accorded with the blade number of the runner for cancelling pressure pulsating waves in pipe water by interference.
