ABSTRACT:
A lubrication device employing a reciprocable plunger, as the actuating member, which is driven by a rotatable cam member through a pivoted rocker arm engaged with the plunger and having roller means engaging the cam, with the axis of the plunger, respective pivotal axes of the cam, arm and roller means, and line contacts between the roller and cam and between plunger and arm being so related that actuating forces are transmitted from the cam to the plunger substantially on the axis of the plunger, substantially eliminating undesirable lateral forces on component parts and enabling the use of simple bearing structures for the cam shaft. Operation is further improved by a novel disposition of valve means in the lubricant supply line.
