ABSTRACT:
A variable camshaft phaser (VCP) has lash take up drive piston assemblies with inner and outer helical splines for phase changing and return springs mounted in pockets in the pistons to shorten overall length for a compact unit and also relieve lash take-up friction on the piston return strokes. Numerous other features are included. A three-way feed-discharge valve limits oil flow to that necessary to operate the drive pistons for phasing.
