Silencer for Hydraulic Piston Pump Pressure Pulsations 911759

The hydraulic piston pumps that are used on off-highway vehicles create pressure pulsations that may generate excessive noise in the vehicle. The most effective method of reducing this noise is to decrease the amplitude of the pressure pulsations leaving the pump by using a reactive type of silencer. A reactive silencer changes the load impedance and reflects the pulsations back to the pump. This paper develops the insertion loss for a specific type of side branch resonator, called a cross-loop attenuator, and describes the design parameters that will result in the best insertion loss for a piston pump application.
