Abstract
A pressure pulsation trap is provided. The pressure pulsation trap includes a channel extending from an inlet to an outlet, and a plurality of branches extending from the channel, each of the branches having different lengths than one another. The different lengths are configured such that the branches attenuate noise and/or vibration over a range of operating frequencies.
