Noise attenuation device and fluid coupling comprised thereof

摘要: Embodiments of a noise attenuation device (100) comprise plurality stacked plates (114) that form channels to reduce energy in flow working fluid transits the device. In one embodiment, include having openings different patterns. Orientation align patterns housing channels. example, are disposed coupling (e.g., valve and/or regulator) includes throttling element. The spaced apart from element, thereby permitting through all whether element is fully or partially open.
