Abstract
A lubricant injector includes an injector body having an inlet port fluidly coupleable with a lubricant supply, an outlet port fluidly coupleable with a lubrication point, a piston chamber and a valve chamber. A piston is disposed within the piston chamber and defines a measuring section and an actuating section, the piston being linearly displaceable along an axis through the piston chamber so as to inversely vary the volume of the chamber measuring section and the volume of the chamber actuating section. A valve member disposed within the valve chamber is displaceable along an axis through the valve chamber between a first position, at which the inlet port is fluidly coupled with the piston chamber actuating and measuring sections, and a second position at which the inlet port is fluidly coupled with the piston chamber actuating section and the outlet port is fluidly coupled with the piston chamber measuring section.
