Abstract
An air pressure regulator includes a housing having inlet and outlet ports extending along a common axis. A movable valve member and a piston are positioned in the housing on opposite sides of a housing flow passage. The movable valve member is adjacent the inlet port while the piston is adjacent the outlet port. The piston has a central stem extending through the housing flow passage in radially-spaced relationship thereto for engaging the movable valve member. The piston is normally biased in a direction toward the movable valve member for holding same displaced from a seat around the housing flow passage. When a predetermined pressure exists at the outlet port, the piston moves away from the movable valve member for allowing same to move into engagement with a seat around the housing flow passage for closing such passage.

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.
