  7. Reservoir/Sump: A tank that stores the lubricating oil and supplies it to the pump.
  8. Σωλήνας αναρρόφησης: Draws lubricating oil from the reservoir into the pump.
  9. Φίλτρο λαδιού: Removes impurities from the lubricating oil before it circulates through the system.
  10. Πλάκα συναρμολόγησης: Secures the pump firmly to the machine or engine block.
