Title:

OIL SEPARATOR

Document Type and Number:

WIPO Patent Application WO/2017/175324

Kind Code:

A1

Abstract:

By eliminating a through-hole that was provided to the central side of a lower holder 72 in a rotor 60, a decrease in separation efficiency can be avoided without sucking in large drops of mist, which are not present at low temperatures, even when oily smoke produced at high temperatures is sucked in. By providing a first partition 31b to the upper face side of a lower partition member 31, an inner wall face 22f of a case 22 is made to hang at a gap 43a in the outer periphery of the lower part of the rotor 60, which serves as a way out for blow-by gas having an ultrahigh flow-rate, oil to be discharged is prevented from being dragged around by a swirling flow caused by the rotation of the rotor 60 and is prevented from accumulating at the inner wall face 22f of the case 22. As a result, oil heading downward and gas heading in the opposite direction can pass one another without interfering with one another, such that a continuous discharge of oil toward a lower case 21 from a separation chamber 43 containing the rotor 60 is enabled, and oil-sinking of the rotor 60 can be prevented by preventing oil from collecting in the separation chamber 43.
