The invention concerns a rotary piston adjuster (1, 1') for hydraulic phase adjustment of a camshaft of an internal combustion engine relative to a drive pinion (6), said adjuster comprising a rotor (3, 3') fixed to the camshaft and cooperating with the drive pinion (6) for effecting phase adjustment. Due to the fact that annular hydraulic chambers (14, 14') are arranged in the peripheral region of the rotor (3, 3') and comprise an outer and an inner limiting wall (15, 15', 16) and radially extending vanes (18, 18') acting as separating walls, said hydraulic chambers (14, 14') being divided by segments (8, 8') that are axially connected to the drive pinion (6) into active oil chambers A and B with sealing clearance that can be loaded by pressure oil, and further due to the fact that the segments (8, 8') possess an anti-racing device and an eccentric pivot bearing (19) having radial play, a rotary piston adjuster is obtained that is simple to manufacture and to mount while being endowed with high efficiency and a high functional quality.
