DEAERATOR

WIPO Patent Application WO/2006/120965

A1

A deaerator capable of suppressing the lowering of sealability (lowering of airtightness) while eliminating the arrangement of a seal member between a container and a cover body forming a depressurized chamber. The deaerator comprises the depressurized chamber having the cylindrical container extended along its center axis and the cover body sealing the opening part of the cylindrical container at its end part and a gas permeable tube stored in the depressurized chamber so that a liquid to be deaerated flowing from the outside of the depressurized chamber therein can pass the inside thereof and the liquid passed through the inside can flow out of the depressurized chamber. A first tilted surface tilted at a prescribed angle Ѳ relative to its center axis and apart from the center axis toward the opening side of the container is formed on the inner peripheral surface of the container near the opening part. A second tilted surface tilted at a prescribed angle Ѳ relative to its center axis and close to the center axis toward the inner side of the depressurized chamber is formed on the contact part of the cover body on the container in the sealed state of the opening part. The opening part is sealed by connecting the container to the cover body in the contact state of the first tilted surface on the second tilted surface.
