| 20080289593 | SWITCHABLE VALVE TRAIN FOR GAS-EXCHANGE VALVES OF INTERNAL COMBUSTION ENGINES - A switchable valve train for gas-exchange valves of internal combustion engines with a rocker arm device ( | 11-27-2008 |
| 20090007871 | VALVE TRAIN OF AN INTERNAL COMBUSTION ENGINE HAVING A CYLINDRICAL VALVE TAPPET - The invention proposes a push-rod valve train having an adjustable valve tappet ( | 01-08-2009 |
| 20090007872 | SWITCHABLE DUAL LIFTER - The switchable dual lifter has two hydraulic lash adjusters, one which is fixed within the common housing, and the other which is movable to allow for deactivation of one of the two valves acted on by the dual lifter. Using the dual lifter with a switchable hydraulic lash adjuster allows for closing of one of the adjacent valves while allowing the other of the adjacent valves to operate. | 01-08-2009 |
| 20090013950 | DUAL VALVE LIFTER ASSEMBLY - The dual valve lifter assembly has a dual valve lift with two hydraulic lash adjusters therein and a guide for orienting and preventing rotation of the dual valve lifter. The guide has four ledges and the dual valve lifter has four flats which mate with the four ledges. The flats and the ledges prevent the rotation of the lifter. One pair of flats and one pair of ledges are spaced the same while the other pair of flats and the other pair of ledges are spaced at a different distance than the first pair of flats and ledges. The difference in the spacing of the pairs of ledges and flats allows for correct orientation of the lifter when mating it with the guide. | 01-15-2009 |
| 20090031969 | FREELY ROTATABLE HYDRAULIC PIVOT ELEMENT - The freely rotatable hydraulic pivot element for an internal combustion engine has four oil inlets which are in fluid communication with the lash adjusting element inside the pivot element and in fluid communication with the oil gallery by using four more equally spaced oil inlets in the outer housing of the cylinder head while still in fluid communication therein. The use of four or more oil inlets are in the same radial plane of the outside cylindrical housing of the pivot element. | 02-05-2009 |
| 20090031977 | LOW PROFILE VALVE LIFTER ASSEMBLY - The low profile valve lifter assembly has flats inside the bore of the outer housing and walls are formed and extended down from the plate of the guide such that the walls align with the flats of the bore to prevent rotation of the lifter with the guide. A groove and protuberance are provided in the flats and on the side wall of the guide in order to properly orient the lifter with the guide. The flats can be connected to form a pocket and the walls of the guide can be connected to form a sleeve that mates with the pocket. | 02-05-2009 |
| 20090151668 | DEVICE FOR COUPLING VALVE ACTIVATING LEVERS OF AN INTERNAL COMBUSTION ENGINE - Device for coupling two valve activating levers of an internal combustion engine with at least one carrier body ( | 06-18-2009 |
| 20090159030 | SWITCHABLE HYDRAULIC LASH ADJUSTER WITH SPHERICAL LOCKING PINS - The switchable hydraulic lash adjuster uses balls that move radially in order to lock and unlock the switchable elements in the hydraulic lash adjuster. An axially movable piston acts on the ball to force it to engage and to allow it to disengage the inner housing. | 06-25-2009 |
| 20090173302 | SWITCHABLE DOUBLE TAPPET - A switchable double tappet ( | 07-09-2009 |
