Abstract

Official abstract text for this publication.

An oil separator includes a case and introduces blow-by gas of an internal combustion engine into the case. The oil separator then separates oil from the blow-by gas and discharges the separated oil from the case. The case incorporates electrode plates, which are arranged at intervals and face each other. A filter is arranged between any adjacent two of the electrode plates. The filter is formed of fibers, which are made of an electrically insulating first material, or polyester. A potential difference is created between the electrode plates.

First claim

Opening claim text (preview).

The invention claimed is: 1. An oil separator comprising a case, wherein the oil separator is configured to introduce blow-by gas of an internal combustion engine into the case, separate oil from the blow-by gas, and discharge the separated oil from the case, and the case includes: electrode plates, which are arranged in the case to face each other at intervals, wherein a potential difference is created between the electrode plates; and a filter, which is made of an electrically insulating first material and arranged between the electrode plates, wherein the first material is a first plastic, and the filter is formed of fibers made of the first plastic, and wherein a surface of each fiber is provided with a second material, which has a higher electric resistivity than that of the first plastic. 2. An oil separator comprising a case, wherein the oil separator is configured to introduce blow-by gas of an internal combustion engine into the case, separate oil from the blow-by gas, and discharge the separated oil from the case, and the case includes: electrode plates, which are arranged in the case to face each other at intervals, wherein a potential difference is created between the electrode plates; and a filter, which is made of an electrically insulating first material and arranged between the electrode plates, wherein the first material is a first plastic, and the filter is formed of fibers made of the first plastic, and wherein each fiber contains a third material, which has a higher relative permittivity than that of the first plastic.
