  • Breather apparatus of internal combustion engine
    Patent number: 6899091
    Abstract: A breather apparatus includes a first oil separation chamber disposed in a case and extending substantially in a vertical direction. The case constitutes a part of a vertical wall of an internal combustion engine, and blowby gas flows inside the case. A second oil separation chamber is superposed upon the first oil separation chamber. An opening formed in the lower part of the first oil separation chamber is communicated with the inside of the case. An upper part of the second oil separation chamber is communicated with the first oil separation chamber via a through hole. The blowby gas which has flown into the second oil separation chamber is supplied into an intake system via an outflow port formed in the lower part of the second oil separation chamber. In the separation chambers, oil in the blowby gas is separated by mutually different flow characteristics.
