Patent ID: 8181671

Claim:
An anti-resonant pulsation diffuser comprising: an elongate flow tube having an interior cross-section surrounding a long axis, an inlet end aligned with the long axis for receiving a fluid flow and an outlet end for discharging the fluid flow; a diffuser plate spanning the entire interior cross-section to separate the flow tube into an inlet chamber and an outlet chamber, the diffuser plate having a plurality of apertures formed therein for directing the fluid flow from the inlet chamber to the outlet chamber; and wherein the diffuser plate is longitudinally orientated at a shallow angle with respect to the long axis of the flow tube to provide a substantially smooth indeterminate pulsation reflective surface spanning the entire cross-section directly in line with the inlet, with the inlet chamber gradually decreasing in cross-sectional area and the outlet chamber gradually increasing in cross-sectional area across the length of the flow tube.
