Abstract

Hydrostatic machine that includes a block or barrel provided with a plurality of cylinders in which pistons that cooperate with an inclined drive disc move, and a distributor plate of adjustable position (for example by rotation) that has two ports connected, respectively, to the sources of low and high pressure by means of ducts that pass through a fixed cylinder head, including this distributor plate, in addition, channels that flow into the areas located between the ports that the plate passes through and capable of being put into communication with one or the other port, characterized by the fact that the holes through which said channels open onto the areas are distributed in such a way that their sealing varies with the position of the distributor plate, ensuring a significant covering angle for a plate position angle distributor corresponding to full capacity operation, and so much less when the angle position corresponds to operation over small displacement.
