摘要
A pulsation attenuator for a fluidic system with a fluidic pump. The pulsation attenuator includes a fluidic channel, a first fluidic device adapted to attenuate pulsations with a shallow rolloff slope, and a second fluidic device adapted to attenuate pulsations with a shallow rolloff slope. The first fluidic device and the second fluidic device are connected to the fluidic channel such that they cooperatively attenuate pulsations with a steep rolloff slope. Preferably, the first fluidic device includes a first fluidic resistor and a first fluidic capacitor, and the second fluidic device includes a second fluidic resistor and a second fluidic capacitor. Preferably, the pulsation attenuator is arranged, similar a second-order low-pass filter, in the following order: (l) first fluidic resistor, (2) first fluidic capacitor, (3) second fluidic resistor, and (4) second fluidic capacitor.
