摘要:
A suction flow regulator including an adapter and a grommet fixed inside the adapter for permitting air to access a vacuum flow path according to a vacuum level. The grommet is fixed inside an adapter by a securing mechanism (for example, a compression plate). The grommet may be used with an additional elastomeric element (for example, a smaller grommet) that provides flexibility during vacuum exposure and deflects to expose holes in the grommet under vacuum. Alternatively, the grommet may be a single unit grommet with a cantilever configuration.
