    2017-10-1 · Pressure pulsations caused by such positive displacement pumps can lead to malfunctions and noise in a hydraulic system. A common measure to reduce pressure pulsations is the integration of pressure pulsation dampers downstream of the pump. This type of damping measure can also be found in biology as e.g. in the human blood circulatory system. Such …

A 1 ml air pocket trapped above the liquid absorbs the pulses and a smooth flow exits the pulsation damper. It absorbs the oscillating pressure due to the trapped air being more compressible than fluid.
