Abstract: Centralized greasing installation, each stage of which comprises a metering iston (12) with two rods (19, 20), the ends of each of the two rods (19, 20) sliding respectively inside a lubrication chamber (21) and a resetting chamber (22), said chambers being supplied with air and connected to the atmosphere by a bore (23, 24) of an adjusting stopper (17, 18) which is closed by the end of the corresponding rod at the end of corresponding lubrication and resetting travel of the piston (12), with means for detecting the establishment of pressure, wherein the various lubrication air chambers (21) are connected together and to a common air source having a limited flow rate as well as to a common pressure switch, while the various resetting air chambers (22) are placed in communication with each other and with another compressed-air source having a limited flow rate and to another pressure control switch, in order to verify, with limited means, that between the resetting phase and the lubrication phase, all the mete
