Abstract
A converter of the rate of flow of a fluid is disclosed with a measuring chamber having a smooth internal outer surface and a cylindrical casing, disposed in the base of the eternal casing of the converter. An inlet chamber of a damper is formed from the side of a flexible membrane in the converter. Between the cylindrical casing and the base of the external casing, a free (clear) annular space is provided. On the external wall of the first half of said chamber there is a hole, while on the external wall of the other half of said chamber there is a compensation hole disposed in front of the tangential inlet of the cylindrical measuring chamber. A turbine wheel, disposed inside the chamber, has flat rectangular blades. In the axial outlet of the cylindrical measuring chamber, a guiding element is disposed with bottom and top transverse bases having the shape of circular sectors. The bottom and the top transverse bases are interconnected by a spiral surface in such manner that the circular section of the transverse base is disposed in front of the free section. Between the axial outlet of the cylindrical measuring chamber and the outlet chamber of the damper, a hydraulic throttle is shaped in the base of the external casing of the converter.

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.
