<p>A flow-through pressure regulator (10) includes a retainer (302) that secures a diaphragm (300) relative to a seat (304), and includes an intermediate portion (320), an end portion (322) and a base portion (332). The intermediate portion (320) extends along a longitudinal axis and is fixed with respect to the seat. The end portion extends from the intermediate portion and includes a concave surface facing the seat. The regulator includes multiple flow diffusers such that the end portion includes at least one aperture (326) having a flow axis that is oblique to the longitudinal axis so as to reduce noise due to fluid flow and/or the seat forms a passage having an increasing cross-sectional area from an inlet to an outlet</p> |
