ABSTRACT:
A variable camshaft timing mechanisms having a vane/housing format is provided. Working hydraulic chambers are created by imposing either single or multiple vanes of a rotor attached to the camshaft into a cavity in a housing that is attached to the camshaft sprocket. Fluid is allowed to normally exhaust from the hydraulic chamber during normal phasing until the rotor nears the end of its travel.
