Abstract: A camshaft phaser assembly for a concentric camshaft that adjusts the relative rotational position of the inner camshaft relative to the outer camshaft and the crankshaft of an internal combustion engine is provided. The phaser has an inner rotor with radially outwardly extending vanes which is attached to the inner camshaft. The rotor is surrounded by a stator having radially inwardly directed projections which contact the outer surface of the rotor and form working spaces into which the vanes extend. The vanes divide the working spaces into first and second sets of pressure chambers which can be pressurized with a hydraulic medium in order to rotate the rotor in an advancing or retarding direction. Front and rear covers are attached to the stator and define the front and rear sides of the pressure chambers. The timing gear or timing belt pulley is connected to the stator. The rear cover includes a splined opening.

Abstract: A camshaft adjuster for a concentric camshaft assembly of an internal combustion engine is provided. The adjuster includes a stator that is connected to the timing gear, and a rotor located within the stator having a plurality of vanes that extend into spaces created between inwardly directed projections of the stator to define chambers on each side of the vanes. Front and rear sidewalls are connected to the stator and form the front and rear walls of the chambers. An outer cover connects to the stator to the inner camshaft via a drive adapter, and the rotor is connected to the outer camshaft. Radial loads acting on the timing gear are transmitted from the stator to the rotor and into the outer camshaft. The drive adapter includes an open cylindrical body having first and second ends. The first end includes a slot or recesses in which a timing feature of the cover engages. The second end has a keyed portion configured to matingly engage a corresponding portion of the inner camshaft.

Abstract: A camshaft adjuster for a concentric camshaft of an internal combustion engine is provided. The adjuster includes a stator that is connected to the timing gear, and a rotor located within the stator and connected to the outer camshaft. The rotor includes a plurality of vanes that extend into spaces created between inwardly directed projections of the stator that slidingly engage the outer surface of the rotor to define first and second sets of chambers on each side of the vanes. Front and rear sidewalls are connected to the stator and form the front and rear walls of the chambers. An outer cover is connected to the stator via axially extending fasteners and is adapted to be connected to the inner camshaft. Radial loads acting on the timing gear are transmitted from the stator to the rotor and into the outer camshaft.

Abstract: The camshaft adjuster is a plurality of return springs which are in parallel to one another in a spring.

Abstract: A computer-implemented navigation method for implementation during a navigation routine for directing a user is provided. The navigation method comprises generating a navigation route. GPS signals are received and position fixes are derived from the GPS signals. The position fixes are stored and compared with the navigation route. A threshold value is determined based on the comparison of the position fixes with the navigation route. An updated navigation route is generated based on the plurality of position fixes distanced from the navigation route a distance greater than the threshold value and an updated navigation route is not generating based on the plurality of position fixes distanced from the navigation route a distance not greater than the threshold value. A mobile device for performing a navigation procedure is also provided.
