ABSTRACT:
A timing element for a lubricant supply system is capable of using pneumatics for the time of delivery of lubricant for a preset duration. In one example, the timing element has a cavity having an entrance and an exit, a first piston and a second piston. The first piston and the second piston are disposed in the cavity. The first piston is coupled to the second piston in such that compressed air in the entrance of the cavity is capable of moving the second piston and closing the exit. A pneumatic timing element may be incorporated into a dosing unit that is capable of supplying an amount of lubricant in a mist to a plunger bushing of a machine tool without. The duration of the dosing may be controlled solely by pneumatics and may prevent excess pooling of lubricant in bore holes by shutting off lubricant delivery at a preset time.
