Bubble separator

Abstract

A bubble separator includes a body with a generally cylindrical shape, an oil induction portion, a gas discharge portion with a generally cylindrical shape, an oil discharge portion, and an upper partition. The oil induction portion is provided on the body, and introduces bubble-containing oil to inside the body. The gas discharge portion is provided extending from a ceiling portion of the body, and discharges separated bubbles to outside the body. The oil discharge portion is provided on the body, and discharges separated oil to outside the body. The upper partition is provided extending from the ceiling portion, and is formed on a periphery of the gas discharge portion. According to the bubble separator of the present invention, the upper partition can prevent bubble-containing oil from directly blowing into the discharge hole of the gas discharge portion and discharging to outside the body together with separated gas.

Claims

1. A bubble separator that is a centrifugal separation type for eliminating bubbles included in oil used by a lubrication system for an internal combustion engine, the bubble separator comprising: a body with a generally cylindrical shape;an oil induction portion that is provided on said body, and introduces bubble-containing oil to inside said body;a gas discharge portion with a generally cylindrical shape that is provided extending from a ceiling portion of said body, and discharges separated bubbles to outside said body;an oil discharge portion that is provided on said body, and discharges separated oil to outside said body; andan upper partition that is provided extending from said ceiling portion, and is formed on a periphery of said gas discharge portion.

2. The bubble separator according to claim 1, wherein said gas discharge portion has a plurality of discharge holes on a front surface thereof, and a total opening area of said discharge holes positioned above a lower end of said upper partition is greater than a total opening area of said discharge holes positioned below said lower end of said upper partition.

3. The bubble separator according to claim 1, wherein said gas discharge portion has a plurality of discharge holes on a front surface thereof, and an opening area of said discharge holes progressively decreases toward a downward direction from said ceiling portion.

4. The bubble separator according to claim 1, wherein said gas discharge portion has a plurality of discharge holes on a front surface thereof, and an opening interval of said discharge holes progressively widens toward a downward direction from said ceiling portion.

5. The bubble separator according to claim 1, wherein said lower end of said upper partition is positioned below a lower end of said oil induction portion.

6. The bubble separator according to claim 1, further comprising: a lower partition that is positioned on a lower side of said gas discharge portion, and isolates said separated bubbles and said separated oil.
