Title
(EN) OIL SEPARATOR
(JA) 油分離器
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide an oil separator that suppresses re-scattering of oil that is separated at a curved part.

SOLUTION: An oil separator that is a centrifugal separation type oil separator includes: a cylindrical separator body 70; and an inflow pipe 50 that introduces oil-containing fluid into the separator body 70 and has a curved part 60. The curved part 60 is formed with at least one oil drainage hole 90, thereby having a structure for separating oil.
