Abstract
A two-stage aerator manually operable to provide either a low-volume spray or a high-volume stream. A valve poppet maintains the aerator in the selected position so long as water is flowing through the aerator. The low-volume spray position is the default, and the aerator includes a resilient diaphragm to return the aerator to this position whenever water flow is terminated.
