PURPOSE:To prevent the occurrence of noises by forming a discharge port of a fluid ring pump with an aggregate of fine paths to discharge fine bubbles of discharged gas into enclosed liquid. CONSTITUTION:A discharge port 5 of a fluid ring pump is formed of an aggregate of fine paths and formed on the outside with a discharge chamber 7 in which enclosed liquid is reserved. Gas compressed in a pump chamber is changed into fine bubbles as it passes through the discharge port 5 and injected into the enclosed liquid in the discharged chamber 7 to be discharged from a discharge pipe 3. As the discharged gas is discharged as fine bubbles, noises then are not produced. |
