Abstract
A system for distributing measured quantities of viscous lubricant to a plurality of lubricating points. The system includes a plurality of injector cylinders and a container for viscous lubricant. A selectively operable hydraulic fluid pressure supply pump supplies hydraulic fluid to an hydraulic cylinder for pressurizing lubricant in the container at a low pressure to feed lubricant to the injector cylinders, and the fluid pressure supply pump supplies hydraulic fluid at a high pressure to the injector cylinders to feed lubricant to the lubricating points.
