Abstract
A fluid discharge pipe structure comprises a cylindrical body, an inlet side connection member having a through hole formed in one end part of the cylindrical body, an outlet side connection member having a through hole formed in another end part of the cylindrical body, a spiral blade body having spiral blades on an outer circumference thereof and provided close to the inlet side connection member of the cylindrical body, and a flip-flop phenomenon generating shaft body provided close to the outlet side connection member of the cylindrical body.
Claims20
A fluid discharge pipe structure comprising:
- a cylindrical body;
- an inlet side connection member, having a through hole, to be attached to one end part of said cylindrical body;
- an outlet side connection member, having a through hole, to be attached to another end part of said cylindrical body;
- a spiral blade body, having spiral blades on an outer circumference thereof, to be positioned within said cylindrical body at the one end part of said cylindrical body;
- and
- a flip-flop phenomenon generating shaft body to be positioned within said cylindrical body between said spiral blade body and an outlet of said through hole of said outlet side connection member when said spiral blade body is positioned within said cylindrical body and said outlet side connection member is attached to the another end part of said cylindrical body, said flip-flop phenomenon generating shaft body including
- (i) a truncated conically shaped first end part,
- (ii) a conically shaped second end part,
- (iii) a shaft part between said truncated conically shaped first end part and said conically shaped second end part, and
- (iv) diamond-shaped projecting parts arranged with predetermined regularity on an outer circumferential surface of said shaft part.
A fluid discharge pipe structure comprising:
- a cylindrical body;
- an inlet side connection member, having a through hole, to be attached to one end part of said cylindrical body;
- an outlet side connection member, having a through hole, to be attached to another end part of said cylindrical body;
- a spiral blade body, having spiral blades on an outer circumference thereof, to be positioned within said cylindrical body at the one end part of said cylindrical body;
- and
- a flip-flop phenomenon generating shaft body to be positioned within said cylindrical body between said spiral blade body and an outlet of said through hole of said outlet side connection member when said spiral blade body is positioned within said cylindrical body and said outlet side connection member is attached to the another end part of said cylindrical body,
- wherein said inlet side connection member includes a rectifying space part for rectifying fluid flow adjacent said spiral blade body when said inlet side connection member is attached to the one end part of said cylindrical body and said spiral blade body is positioned within said cylindrical body.
