A LUBRICATOR Abstract of the Disclosure The lubricator of the invention is a one-shot or non- continuous type. It has a first reservoir within which to receive a charge of lubricant, and a second reservoir from which to expel a charge of lubricant, and a piston slidable therebetween for moving lubricant from the first reservoir to the second reservoir, and also for dischar- ging lubricant from the second reservoir and externally of the lubricator. Upon the piston moving, slidably, in a first direction it creates a partial vacuum in the first reservoir and, consequently, ingests lubricant into the first reservoir. Then, as the piston moves in the second, opposite direction, it diminishes the volume of the first reservoir, and displaces lubricant therefrom through a channel formed centrally in the piston. The lubricant conducted through the channel is deposited in the second reservoir, and is expelled therefrom, by the piston, when next the piston moves in the first, slidable direction.
