Claims

[Claims for Utility Model Registration] 1. The oil separator is constructed so that the blow-by gas leaked from the combustion chamber 2 of the engine 1 to the crank chamber 7 is returned to the combustion chamber 2 through the oil separator 30 and the intake passage 17 in this order. 30 is configured to pass the blow-by gas from the gas inlet 33 of the separator main body 31 to the gas outlet 48 through the inlet chamber 34, oil separation layer 35 and outlet chamber 36 in order, and the inlet chamber 34 is connected to the engine 1 through the oil return path 39. In the engine blow-by gas combustion chamber reduction device configured by communicating with the oil pan 5 and communicating the inlet chamber 34 with the atmosphere through the atmosphere communication section 40, the atmosphere communication area determines the passage cross-sectional area of the atmosphere communication section 40. A combustion chamber reduction device for blow-by gas in an engine, characterized in that a determining tool 41 is formed separately from a separator main body 31 as an independent component and assembled by fitting. 2. The atmosphere communication area determining device 41 is composed of a covered cylinder 42, and the legs 42a of the covered cylinder 42 are connected to the separator main body 3.
1, an atmosphere communication port 43 is formed in the cylindrical body portion 42b, and a flange 44 protrudes from the outer periphery of the lid portion 42c. Combustion chamber reduction device for engine blow-by gas. 3. The combustion chamber reduction device for blow-by gas in an engine as set forth in claim 1, wherein the atmosphere communication area determining device 47 comprises a screw member 47 that adjusts the opening degree of the atmosphere communication hole 43 of the atmosphere communication portion 40.
