Abstract: Composite cap intended to be snapped on the glass ring of a bottle and then to serve as a stopper that can screwed and unscrewed as required, the glass ring being provided with at least one annular bead. It comprises a shell with a skirt provided with an internal annular bead; a first insert, disposed inside said shell, provided with an internal screw thread, characterized in that it also comprises a second insert having at least two roughly cylindrical portions; the first portion being provided on its external wall with a screw thread complementary to that of said first insert, the second portion being provided with axial immobilization means intended to cooperate with said annular bead and axial stop means, cooperating with said internal annular bead, so that the inserts secured together by screwing are trapped inside said shell.

Abstract: A recirculation device includes an air intake duct (3) which is followed by a manifold (6), means for introducing recycled exhaust gases, for mixing same with the fresh air let in. This device is designed to inject the exhaust gases by forming two counter-rotating adjacent vortices (14, 15), owing to a twin tubular mixer nozzle (10, 11) in communication with a common exhaust gas supply duct, positioned tangentially with respect to the two nozzles, placed side by side. The two vortices (14, 15) are self-sustaining to the outlets (7) of the manifold (6). Such a recirculation device is applied, in particular, to an air intake duct (3) of oblong cross section and/or to a manifold (6) with a flattened inlet (5) and/or a flattened plenum (8), in particular for a motor vehicle engine.

Abstract: This cyclone device performs diphasic gas-oil separation to remove oil from the recirculated crank cases of an internal combustion engine. Mounted such that it can move vertically inside the cyclone is a body (7) exhibiting symmetry of revolution, particularly one of cylindro-conical overall shape. The body (7) delimits, with the walls of the cylindrical collecting zone (2) and/or of the conical zone (3) for recuperating the liquid oil, an annular gap (13) such that the passage cross section can vary according to the self-adjusting heightwise position of the body (7), as a function of the gas flow rate. The speed of the gases thus remains constant for variable gas flow rates.

Abstract: The invention relates to an oil separator (1) for an internal combustion engine, for at least partially separating the oil from the gases exiting the crankcase of an internal combustion engine, which separator comprises a casing (10) containing therein: an inlet chamber (2) for the oil-laden gases; an outlet chamber (3) for the cleaned gases; at least one intermediate suction chamber (41, 42, 43); and an oil recovery chamber (5) with an opening (50) for returning the separated oil to the engine. The communication interface (53) between the oil recovery chamber (5) and the gas outlet chamber (3) is sized (Ll) in such a way that the pressures in each of the chambers (3, 5) are substantially equal during the use of the separator regardless of the gas flow rate inside said separator (1). The invention can be used in the field of motor vehicles.

Abstract: The inventive oil separator provided for de-oiling a gas exhausted from a crankshaft case (1) comprises oil collecting means (11) associated with a siphon (12) whose inlet inside the oil separator (7) is encompassed by an oil recovery chamber (13) provided with a perforated wall, at least a small oil recovery hole (14) arranged in the lowest part of the chamber (13) at the exit of the collecting means (11) and at least one depressurising small hole (15) which is arranged in the highest part of the chamber (13) above a clarified oil surface and is connected to the chamber (13) at a depressurising point (16). Said invention is usable for internal combustion engines.
