PURPOSE:To feed a flow of fluid with a minute flow rate without causing the pulsation, by utilizing a sliding bearing provided with an obstacle to its internal surface as a pump. CONSTITUTION:A pump 6 is constituted by utilizing a journal sliding bearing and formed by the journal sliding bearing 10 supporting a rotary shaft 9 connected to a transmission shaft 8 through an oil film 3a and an obstacle 12 protruded to an internal surface of the bearing 10. The shaft 9 is rotated in the inside of the pump 6, consequently petroleum 3 becomes the oil film 3a to flow in the same direction as the shaft and collide with the obstacle 12 then generate negative pressure in the vicinity of a flow inlet 13 while positive pressure in the vicinity of a flow outlet 14. In accordance with this pressure difference, a fixed flow of petroleum is continuously fed further without causing pulsation. |
