Abstract
An infinitely variable phase adjuster for e.g. adjusting internal combustion piston engine valve timing by selecting the relative rotational positions of the engine crankshaft and a camshaft of the engine. Control is effected by adjusting a "lock" volume of oil on one side of a pressure fluid operable member displaceable to shift the phase.
