Method for reducing noises caused by fluid pulsation involves hydraulic system, which with help of rotating pulsation-valve produces pressure pulsation, which partly compensates fluid pulsation

摘要

The method involves the hydraulic system, which with the help of a rotary pulsation-valve produces the pressure pulsations, which partly compensate the fluid pulsations. The rotary pulsation valve is synchronous with the rotary pump and is preferably driven by its drive shaft. An independent claim is also included for the device for reducing the noises caused by fluid pulsation.
