The normal position, of Jche spring arm n is that represented in Fig. 5 und tending to move the vulve i so es to almost close the outlet pes-sage o2; this position of die vulve ciuiesponding *with the fully charged cup in which the plunger ca is mised to its highest point end the v,equii-ng 1 is fully compressed, thus insuring maximum downward pressure upon the' plunger to forcethe lubricant from the cup. As the Volume of lubricant decreases, however, end ehe-spiing n expands, the @fessure upon the plunger c2 gradually diminishes and in o'clei1 to osei, this dimil'ijution ofpressure the valve a' should he moved so es to gradually open the discharge ps sage 152 in proportion to such diminution of pfessu're upon the lubricant.
