| 20120073529 | TRANSMISSION DEVICE BETWEEN TWO CAMSHAFATS OF AN INTERNAL COMBUSTION ENGINE - An internal combustion engine includes a driving shaft, a pair of camshafts for driving engine valves, a transmission connecting the driving shaft to a first of said camshafts and a transmission connecting the first camshaft to the second camshaft. The transmission connecting the two camshafts to each other includes a pair of articulated parallelogram mechanisms each having two crank members rotatable with end portions of the camshafts and connected to each by means of a connecting rod. The crank members are made up of circular discs eccentrically mounted on the camshafts and rotatably received in circular openings formed at the ends of the respective connecting rod. The two crank members rotatable with the same camshaft are spaced from each other by a determined angle. | 03-29-2012 |
| 20120070274 | Turbocharger Unit with Associated Auxiliary Component, for an Internal Combustion Engine - A unit for an internal combustion engine includes a turbocharger unit and an auxiliary component adjacent to the turbocharger unit and provided with means for connection thereof to the structure of the engine. The auxiliary component has a fluid outlet or inlet arranged immediately adjacent to a fluid inlet or outlet of the turbocharger unit, but not in contact therewith. The unit further includes a cylindrical sealing member, resiliently deformable, having opposite ends sealingly associated respectively to the fluid outlet or inlet of the auxiliary component and to the fluid inlet or outlet of the turbocharger unit. | 03-22-2012 |
| 20110290225 | SEPARATOR DEVICE FOR A SYSTEM FOR RECIRCULATION OF THE BLOW-BY GASES OF AN INTERNAL COMBUSTION ENGINE - A separator device for a system for recirculation of the blow-by gases of an internal combustion engine includes a casing containing a separation chamber and having an inlet for communication with the engine crankcase and an outlet for communication with the engine intake manifold, and drainage outlets ending in the engine crankcase, for returning the liquid separated in the separation chamber into the engine crankcase. Actuator means sensitive to pressure in the engine crankcase are associated to the inlet and to the drainage outlets so that when the pressure in the engine crankcase is higher than the pressure in the separator device, the inlet is open and the drainage outlets are closed, while when the pressure in the engine crankcase is lower than the pressure in the separator device, the inlet is closed and the drainage outlets are open. | 12-01-2011 |
