Abstract
A container for collecting a liquid lubricant has a housing having one end formed with an inlet opening connectable to a source of the liquid lubricant and an opposite end formed with a vent hole, with a piston inside the housing subdividing the housing into a front lubricant compartment into which the inlet opening opens and a rear compartment into which the vent hole opens. The piston is shiftable between a front position close to the intake opening and a rear position close to the vent hole such that as the liquid lubricant fills the lubricant compartment the piston moves into the rear position. Formations on the piston and on the housing seal between the piston and the housing around the vent hole only when the piston is in the rear position.
