Abstract
A rotary internal combustion engine of the Wankel type having a housing with a two lobed epitrochoidal inner peripheral surface, a shaft journalled in end housings and a rotor eccentrically mounted on the shaft and geared to rotate at one third the speed of said shaft whereby working chambers are formed between the flanks of the rotor and the housings which vary in volume as the rotor rotates. The rotor is cooled by a fully closed circuit system wherein pressurised gasses are circulated by a centrifugal fan which is directly mounted on the main eccentric shaft, and circulates the gases through a heat exchanger which is integrated into the cool sector of the rotor housing, all components being enclosed within the pressurised system and only one drive shaft using a single high pressure shaft seal assembly emerges from this system.

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.
