Abstract

An automatic lubrication system for a vehicle, comprising a pump assembly having a plurality of outlet ports, a motor operable to drive the pump assembly, and a cartridge that is attachable to the pump assembly to provide a source of lubricant to the pump. The cartridge is removable from the pump assembly and has an interior space that is collapsible as lubricant is dispensed therefrom. A controller is provided to periodically initiate the motor to cause the pump to dispense lubricant to the outlet ports.
