Abstract
A unified filter and connector housing (24) incorporating a diversion valve assembly (74), the housing assembly being usable with a protective breathing mask assembly (12) of the type requiring separate breathing gas and ventilating gas supply lines (18 and 20). The housing assembly includes first and second housing members (26, 32) which receive therebetween a filter (30) in an airtight relationship. The first housing member is provided with inlets (46, 62) to which quick disconnect supply lines (50, 66) for breathing gases and ventilating gases may be secured. Parallel breathing and ventilating gas passageways (42, 58) are disposed within the first housing member, only the breathing gas passageway normally being in a fluid communication with the filter. The diversion valve assembly (74) is operatively disposed between the breathing and ventilating gas passageways (46, 58) and when disposed in an emergency position opens the communication between the two passageways while substantially blocking the ventilating gas passageway downstream of said opening to cause most of the gas received from either inlet to flow through the filter and into the breathing gas supply line (18) and permitting only a small portion of the gas received from either inlet to pass through the ventilating gas supply line (20).

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
