Abstract
A lubricating system for a machine such as a two-cycle internal combustion engine including a reciprocating pump that pumps a finite amount of lubricant during a single pumping stroke and a stepper motor for operating the pump through incremental phases of movement each less than a stroke. The lubricant requirements of the machine are determined and the driving increments are adjusted so as to provide a pumping stroke when the lubricant consumption of the machine reaches the output of the pump. Various arrangements of stepper motors and control arrangements are disclosed for controlling the amount and timing of the lubricate delivery.
