This system uses a single lubricant distribution line and allows a complete control of the system using a single device that can be installed on any of the metering elements. The pressurized lubricant coming from the pump enters the set of progressive metering elements consisting of a minimum of three elements and, through the internal delivery duct, reaches the right-hand position of piston 1 pushing this leftwards. At the same time, the passage allowing the lubricant to arrive from the line to activate piston 2, moving this leftwards, is opened. In addition to the supply of lubricant form outlet S2, the movement of this piston opens the passageway that allows piston 3 to perform the same operating, with supply of lubricant from outlet S3 and opening the passageway the allows the pressurized lubricant to travel to the left-hand part of piston 1. The other two pistons that complete the lubrication cycle will be moved in sequence. As the movement of a piston is necessary to activate the next piston, all the progressive metering elements of a system are connected in series. Therefore, the blocking of any of the pistons of the metering elements, even those of another set, automatically blocks the whole system. This characteristic is very important for the control of a centralized system. The entire system can be controlled by monitoring any outlet of a metering element with a microswitch or magnetic reed or even better with an inductive sensor
