  • Patent number: 10156169
    Abstract: Provided is an oil separator having a high efficiency in removing oil particles of relatively large sizes. A blow-by gas passage of the oil separator (2) includes an upstream passage (18) and a downstream passage (20) extending at an angle to the upstream passage. A separation wall (36) provided in the downstream passage includes a first surface (40, 78) forming an obtuse angle relative to the upstream passage, and a second surface (42) adjoining the first surface on a downstream side thereof and defining a planar surface extending substantially perpendicularly to the upstream passage. The blow-by gas is accelerated in the upstream passage, and the flow direction of the blow-by gas is changed by the first surface without substantially changing the flow speed and without disturbing the flow before the blow-by gas flows along the second surface. At this time, the oil particles in the blow-by gas collide with and are trapped by the second surface owing to the inertia of the oil particles.

  • Patent number: 10156168
    Abstract: An oil separator for separating an oil in a blow-by gas, includes a housing forming a flow passage, and defining an annular shoulder face facing a downstream side; a valve member reciprocatable between a blocking position abutting an end face thereof against the annular shoulder face to block the flow passage, and an open position separating the end face from the annular shoulder face to open the flow passage; a spring device urging the valve member toward the blocking position; and a reflux device for refluxing the oil separated from the blow-by gas. The valve member includes a first side face facing a wall face of the flow passage and spaced from the wall face at a predetermined interval. A relation wherein a gap between the end face of the valve member and the annular shoulder face in the open position is narrower than the predetermined interval is always established.
