Abstract
A proportional distributor embodying a controlled slide valve and a pressure compensator slide valve associated with additional positioning means whereby the pressure drop in the controlled slide valve depends upon the difference between the working and load sensing pressures according to a linear function with a strictly positive coefficient and a strictly negative constant. Each compensator slide valve operates according to the same linear function or at least one of its proportional distributors has a compensator slide valve operating according to a different linear function.
