Flange and sealing collar assembly

A FLANGE AND SEALING COLLAR ASSEMBLY applied to equipment operating under pressure, equipped with a continuous flow of lubricating oil, characterized in that it comprises a flange (1) and a sealing collar (2), the flange (1) having a substantially cylindrical shape, where in its outer portion it has two cavities (C), a first cavity (C1) and a second cavity (C2), and the cavities (C) extend throughout the outer periphery of said flange (1) and are spaced equidistantly and a communication channel (11), which interconnects the internal portion thereof to the external portion of the equipment through the first central cavity (C1);

• and an interconnected channel (110), which in turn connects the communication channel (11) and the exhaust manifold coupled to the turbocharged system, exerting positive pressure in the first central cavity (C1) and preventing the lubricating oil from returning to the compressor of the turbocharged system;
• further having a sealing collar (2) having a substantially cylindrical shape, provided with a front portion (21) and a rear portion (22), the front portion (21) having a smaller diameter compared to the rear portion (22), wherein said front portion (21) has two diametric recesses, equidistantly and uniformly distributed in it, which receive two piston rings (23a and 23b) and the rear portion (22) has an anterior diametric recess and a another diametral recess.
