Abstract
Official abstract text for this publication.
A phase control apparatus in a variable cam timing (VCT) system of an engine is described herein. The phase control apparatus includes a locking pin coupled to a vane, the locking pin extending into a locking pin recess in a cover plate in a locked configuration, the locking pin and locking pin recess having a backlash and a housing at least partially enclosing the vane and spaced away from the vane forming a gap in the locked configuration.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for operation of a variable cam timing (VCT) system, comprising: actuatably positioning a locking pin in a locking pin recess, the locking pin extending from a vane rotor in the VCT system and the locking pin recess included in a cover plate coupled to a VCT system housing, the VCT system housing spaced away from and not directly contacting a vane in the vane rotor across a full range of all locked pin positions. 2. The m…
