Abstract

Rotating disk for distributing a fluid for actuating propulsion members (13) of hydraulic motors (10), which envisages axial through-channels (31) for supplying/discharging the propulsion members (13), the opposite ends of which emerge inside associated inset seats (32, 36) in its opposite front inner surface (30a) and outer surface (30b), the inner surface (30a) being provided with at least one first balancing eyelet (35) and at least one second balancing eyelet (135) connected to respective fluid supply/discharge ducts (35a, 135a), said balancing eyelets (35, 35) being asymmetrical with respect to a diametral axis of the said disk (20).
