Patent ID: 11898472

Abstract:
A camshaft phaser for an internal combustion engine includes a stator defining a receptacle therein. The stator includes a ring and a plurality of webs extending radially inward from the ring. The camshaft phaser also includes a rotor rotatable with respect to the stator and received inside the receptacle. The rotor includes a center section and a plurality of vanes extending radially outward from the center section. The center section abuts the webs to define chambers circumferentially between the webs. Each of the vanes is positioned in one of the chambers and sealingly engaging an inner circumferential surface of the ring. At least one of the chambers is a locking chamber and at least one the vanes is a locking vane positioned in the locking chamber. The camshaft phaser also includes a locking valve in the locking vane configured to allow fluid to enter into the locking chamber and to prevent fluid from flowing out of the locking chamber to lock the rotor with respect to the stator in a locked orientation.
