Abstract
An apparatus for portional ejection of lubricant for lubrication of railway rails, comprising a tank for lubricant, a dosage pump connected to the tank and driven by an operating unit, a nozzle, and a timer for controlling the operating unit. The operating unit is an electromagnet including a movable armature the movement of which acts upon an ejector piston in the dosage pump. A connecting device is provided between the movable armature of the electromagnet and said ejector piston which establishes a power-transmitting connection only after a predetermined distance of displacement of the armature.
