SIDE BRANCH TYPED DEVICE FOR REDUCING HYDRAULIC PULSATION THROUGH PHYSICAL EVENT BY RELATIVE INTERFERENCE OF PULSATING WAVES

摘要

PURPOSE: A hydraulic pulsation reduction device is provided to extend the life of heavy equipment by preventing a fatigue fracture of a corresponding component. CONSTITUTION: A connection pipe(1) is connected with a main pipe(10). The main pipe carries working fluid from a fluid power source. A block typed housing(12) forms an outer wall by branching and connecting an inlet with the connection pipe and closing an outlet. A bent partition(13) for an inner pipe forms divided plural fluid passages inside the housing and induces the interference of a wavelength for absorbing the pulsation of the fluid to be passed through the main pipe.
