Abstract: A yoke-type phaser is disclosed having a drive member and a driven member rotatable about a common axis and coupled to one another by means of a yoke that is movable, in a plane normal to the common axis, to vary the relative phase of the drive and driven members, by interaction between at least two contact elements and a contoured surface, one of (i) the contact elements and (ii) the contoured surface being connected for rotation with the drive member and the other being mounted on the yoke, each contact element comprising a roller in surface contact with a part-cylindrical recess in a carrier, wherein the carrier of at least one of the contact elements is either appropriately sized or adjustably mounted, to set the clearances between the rollers and the contoured surface.

Abstract: A phasing system for an internal combustion engine having a concentric camshaft includes an annular stator rotatable by the crankshaft and having inner and outer circumferences, and two groups of arcuate cavities. The first group interrupts the inner circumference. A first phaser having an output member as a hub is mounted within the stator in contact with the inner circumference and supported directly on the camshaft tube as a concentric stator bearing. The first phaser has vanes connected to the output member and extending radially into the first group to divide cavities into opposed working chambers. A second phaser comprises first and second end plates at opposite stator sides and fastened to one another to axially seal the cavities therein and, as second output member of the second phaser, connect to vanes extending axially through the second group of cavities to divide the cavities into opposed working chambers.

Abstract: A valve system for an engine includes two cams each having a follower, a summation lever coupled to the followers, a lash adjuster, a valve actuating rocker pivotably coupled to the summation lever and resting on the lash adjuster, a control spring urging the summation lever to compress the lash adjuster, a stop limiting an expansion of the control spring, a bore, a plunger which moves in the bore, and an abutment surface. The control spring acts on the summation lever via the plunger. A plunger end engages with the summation lever. A point of contact between the plunger and the summation lever is displaced in a direction transverse to a plunger axis during a pivoting movement of the summation lever. A plunger shoulder is arranged a distance from the plunger end to contact the abutment surface to limit a plunger displacement in a direction compressing the lash adjuster.
