Abstract

The pumping device (1) takes a part (3) of the fluid (2) which it is pumping for bearing lubrication and engine cooling. There is a chamber (6) in the inflow line (4) taking the part of the fluid for cooling and lubrication, in which this part of the fluid can have its chemical properties altered before being sent on for cooling and lubrication.
