Device for the distribution of hydraulic oil in a rotary table, particularly for machine centres. A vertical cylinder (3) with piston (5) is inserted in the rotary table, which is extended in its lower part by a rod (4) with clearance (41) and a channel (42). The feed channel (21) of the body (2), fitted in the lower part of the rotary table, opens into the rod (4) clearance (41). The feed channel (21) is connected to the hydraulic oil feed (1). The piston channel (51) of the piston (5) links to the channel (42) of the rod (4) and, by its piston rod (52), runs through the axial hole of the horizontally fitted plate (6). In the area of transmission with the piston rod (52) the plate (6) has radial clearance (61), into which the piston channel (51) opens. A horizontal channel (62), forms in the plate (6), links to the radial clearance (61). The horizontal channel (62) opens into the central pin (7), fitted in the plate (6).<IMAGE>
