Devices (10 and 100) for varying the rotational phase relation between a camshaft (12) and an unshown crankshaft in response to positive and negative torque pulsations. The devices include double-acting one-way clutches (24 and 106) disposed in series with support and drive members (20,22 and 102,104) for selectively retarding and advancing the camshaft relative to the crankshaft in response to the torque pulsations. If none of the torque pulsations go negative due to relatively high constant torque, a splitter spring (30) may be disposed in parallel with the one-way clutches.
