摘要

Improvements in the automatic devices of investment, particularly for installations of central lubrication, characterized by the arrangement of an organ that are driving the lubricant alternatively in two pipes between which are connected dosing distributors that are supplying the lubricant in the points to be greased, comprising an automatic inverting member, a distributor that puts the supply line with one of the lubrication lines in communication at the end of the cart, the other one simultaneously communicating with the evacuation, said distributor being operated by hydraulic pressure of the lubricant by one of its end surfaces, while the opposite surface is in relation to that is driven by a second distributor whose terminal surfaces are subjected, respectively, to the pressure that reigns in each of the lubrication pipes, being characterized as well the aforementioned dispenser is provided by the fact that organs are provided to immobilize one of the distributors until the difference in pressure between the two lubrication lines has reached a predetermined value.
