GAS-LIQUID SEPARATION DEVICE FOR BLOW-BY GAS OF ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a gas-liquid separation device for a blow-by gas of an engine which can remove oil mist contained in a blow-by gas while adopting a compact and simple gas-liquid separation structure.;SOLUTION: A gas-liquid separation device for a blow-by gas of an engine includes: a gas-liquid separation chamber 61 provided at a head cover 8 forming an action valve chamber; a partition wall which changes a direction in which a blow-by gas flows in the gas-liquid separation chamber 61; and a blow-by gas suction passage 84 extending from the gas-liquid separation chamber 61 into an intake side action valve chamber 37. An upstream end of the blow-by gas suction passage 84 opens near a bottom wall 28 of the action valve chamber (the intake side action valve chamber 37).;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2018,JPO&INPIT
