| 20080223321 | VARIABLE VALVE ACTUATION SYSTEM FOR AN INTERNAL COMBUSTION ENGINE - A valve system is disclosed for an internal combustion engine which allows a secondary valve event, serving for example to provide internal EGR, to be selectively disabled. The system comprises two valve | 09-18-2008 |
| 20090266320 | VALVE ACTUATING SYSTEM - An actuating system for a gas exchange valve of an internal combustion engine is described which comprises two cams ( | 10-29-2009 |
| 20090272349 | VANE-TYPE PHASER - A vane-type phaser connected to drive an assembled camshaft includes a drive member and a driven member each connected to a respective one of the inner and outer shafts of the camshaft. A first of the members includes a disc with at least one arcuate cavity that is open at both axial ends. The second member includes two closure plates sealing off the axial ends of each cavity of the first member and at least one vane formed separately from the closure plates which is movably received in a respective cavity to divide the cavity into two variable volume working chambers. Each vane is secured at both its axial ends to the two closure plates. | 11-05-2009 |
| 20090293826 | VARIABLE PHASE MECHANISM - A variable phase mechanism is described which comprises a drive member rotatable about an axis, first and second driven members rotatable in synchronism with the drive member, an actuator for rotating the first driven member relative to the drive member to vary the phase of rotation of the first driven member relative to the drive member, and a yoke coupling the second driven member for rotation with one of the drive member and the first driven member and movable transversely relative to the axis of the drive member to vary the phase of rotation of the second driven member relative to the drive member. In the invention, transverse movement of the yoke is effected by means of interaction between the other of the drive member and the first driven member and a radially outwards facing surface defined by the yoke. | 12-03-2009 |

| 20100282193 | Single Cam Phaser Camshaft - A camshaft assembly is disclosed which comprises an inner shaft ( | 11-11-2010 |
| 20100288229 | VALVE MECHANISM FOR AN ENGINE - An internal combustion engine has intake ( | 11-18-2010 |
| 20100294222 | VARIABLE VALVE ACTUATING MECHANISM WITH LIFT DEACTIVATION - An internal combustion engine is described having a valve mechanism that comprises two cams ( | 11-25-2010 |
| 20110017158 | Engine Valve System With Variable Lift and Duration - An improvement is disclosed for an engine valve system with variable lift and duration of the type that includes two cams mounted coaxially, a summation rocker coupled to cam followers in contact with both cams and movable in proportion to the instantaneous sum of the lifts of the respective cams, and a valve actuating rocker pivotably coupled to the summation rocker and serving to open an engine valve in dependence upon the movement of the summation rocker. In the invention, at least one of the couplings of the summation rocker with the cam followers and with the valve actuating rocker incorporates an adjustable eccentric which is rotatable to enable the clearance within the valve system to be set. | 01-27-2011 |
