Patents by Inventor Jacques Pellerin

Jacques Pellerin has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Internal-combustion engine with rotary distribution
    Patent number: 5076219
    Abstract: A rotary bell (36) driven by a hollow shaft (42) and a pinion (46) selectively exposes intake and exhaust ports of the cylinder head (23). The bell (36) delimits a substantially hemispherical combustion chamber (26) and has a progression face (62) which partially protects the piston (1) from the expansion pressure near the top dead center, that is to say when the pressure variation is the most abrupt. The invention is used for improving the combustion, reducing the wear and increasing the operating comfort.

  • Barrel heat engine whose pistons and liners are cooled by a directed fluid flow produced by turbines inside the engine
    Patent number: 4781152
    Abstract: A barrel machine, more particularly a barrel engine cooled by means of turbines (5, 6) disposed around a central shaft (4) and distributing the outside air from the central part of the engine, more particularly inside the pistons and liners. Water and oil can therefore be eliminated, more particularly if an aerosol is used as coolant.
