ABSTRACT:
A lubricator so constructed that a cover provided with a substantially horizontal air conduit including an orifice extending therethrough and formed in its upper side with a supply hole extending therethrough to the orifice is received on the oil cup, a transparent oil drop cylinder including a drop hole extending through its upper side is connected to the supply hole, an adjusting cap integrally provided with a needle valve downwardly projecting from the center of its upper side in alignment with the drop hole and serving to control an aperture of the drop hole is fitted around the oil drop cylinder through thread engagement with the cover or the drop cylinder, an oil reservoir within the oil cup is communicated with the drop hole, and a quantity of oil supplied to the drop hole and dropped through the drop hole into the oil drop cylinder under a suction effect of a pressure differential produced between a pressure acting on the oil surface within the oil cup and a pressure within the orifice is controlled by adjusting the aperture of the drop hole through rotation of the adjusting cap.
