Oil mist separator for use in cylinder head of engine, has gas-liquid separator that include collision portion provided in downstream of nozzle for increasing flow speed of blow-by gas, with respect to flow of gas

摘要

The separator (1) comprises an inlet port (3), an outlet port (4) that are coupled together at a blow-by gas flow path (5) in a cylinder head (2). A gas-liquid separator structure (7) is provided in the flow path for the separation of the gas. A cylinder head cover (8) forming a top wall and a side wall of the flow path, and a guide plate (9) forming a bottom wall of the flow path are provided. The separator structure has a collision portion that is provided in a downstream of a nozzle for increasing a flow speed of gas, with respect to flow of gas.
