| 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 |
| 20080295789 | ROLLER FINGER FOLLOWER FOR VALVE DEACTIVATION - The finger follower has an inner and outer body and a torsional lost motion spring positioned at its lash adjuster end of the outer body The torsional lost motion springs have a short leg that abuts the outer body and a long leg that contacts the inner body. The torsional spring is located above the pivot point of the finger follower so as to provide a low mass moment of inertia and to reduce the weight over the valve stem end of the follower. | 12-04-2008 |
| 20090064954 | SWITCHABLE CAM FOLLOWER OF A VALVE TRAIN ASSEMBLY OF AN INTERNAL COMBUSTION ENGINE - A switchable cam follower of a valve train assembly of an internal combustion engine is proposed, with an external lever that encloses an internal lever with its arms, of which components, that can deviate from each other flexibly, run on an axis that is attached to a valve side end, and the internal lever on an underside on the valve side end possesses a mechanism for a gas exchange valve as well as a complementary surface at the other end for storage on a head of a support element. A special characteristic is that guidance plates for the gas exchange valve come out from the underside of the external lever. That way, the switchable cam follower can be made narrower at least on the valve side. In addition, development of the mechanism for the gas exchange valve on the internal lever is simplified. | 03-12-2009 |
| 20090114177 | ROLLER FINGER FOLLOWER FOR VALVE DEACTIVATION - The finger follower has an inner and outer body and a torsional lost motion spring positioned at its lash adjuster end of the outer body. The torsional lost motion spring has two helical parts each with a short leg that abuts the outer body and a long leg that contacts the inner body. The torsional spring is located above the pivot point of the finger follower so as to provide a low mass moment of inertia and to reduce the weight over the valve stem end of the follower. | 05-07-2009 |
| 20100300389 | Switchable finger lever - The invention proposes a switchable finger lever ( | 12-02-2010 |
| 20100300390 | Swithchable finger lever for a valve train of an internal combustion engine - A switchable finger lever for a valve train of an internal combustion engine, said finger lever comprising an inner lever comprising on an underside on one end, a support for a gas exchange valve and on another end, a contact surface for a head of a support element, said inner lever further comprising on the one end, axle stubs protruding on two sides of the inner lever, a first outer arm extending for pivoting relative to the inner lever on one of the axle stubs and a second outer arm extending for pivoting relative to the inner lever on another one of the axle stubs, said outer arms extending in direction of the another end while flanking outer walls of the inner lever and being made as separate parts from each other, a cam contacting surface being arranged on an upper side of each outer arm while, in the region of the another end, a coupling device for an optional connection of the outer arms to the inner lever is seated in the inner lever, and a restoring spring means for each outer arm acts at one end against the inner lever and at another end against the respective outer arm. | 12-02-2010 |
| 20110005483 | Switchable finger lever - The invention proposes a switchable finger lever ( | 01-13-2011 |
| 20110197842 | SWITCHABLE ROLLER FINGER FOLLOWER - The finger follower employs two independent lost motion arms and a rod which moves longitudinally to lock both arms. The rod is transversely mounted in the follower. In order to avoid premature locking, each arm has a chamfered surface on a top wall to force the rod out of engagement with the arm during upward movement of the arms, to protect premature movement of the rod from an unlocked position to a locked position. | 08-18-2011 |
| 20110197843 | SWITCHABLE ROLLER FINGER FOLLOWER - The finger follower employs two independent lost motion arms and a coupling device that locks both arms. Stops are provided both for the roller axle and for the arm swing. The axle stop and the end stops for the arm swing are positioned on the arm and the outer sidewall of the inner lever. | 08-18-2011 |
