Abstract: 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.

Abstract: The invention proposes a push-rod valve train having an adjustable valve tappet (1). This has an outer part (2a, 2b), an inner part (8) and a lost-motion spring (10), which forces the inner part (8) towards a relative position, at least one retainer ring (23), which is fixed in an annular groove (21) of the outer part (2a, 2b) and which interacts with a stop face (22) of the inner part (8), being provided for fixing the relative position, said retainer ring having lugs (28) extending radially inwards and separated by a fitting gap (27). In this the free movement of the valve push rod (15) relative to the lugs (28) is assured by the provision of a torsional locking means (30a, 30b), which serves to fix the radial position of the fitting gap (27) inside the annular groove (21).

Abstract: A valve train for an internal combustion engine is provided, with the valve train having a switchable rocker arm assembly (1) with a plurality of rocker arms (6, 7, 8) for activating at least one gas exchange valve (2), and also having at least one camshaft (3) with differently contoured cams (4, 5) through which different adjusting displacements can be imparted to individual rocker arms of the rocker arm assembly (1). The assembly further includes a switching device (9) for selectively activating the rocker arms for driving the gas exchange valve (2) with a varying valve lift. To create a valve train in which individual gas exchange valves can be operated in different modes of operation with only a small amount of construction work and expense, the rocker arm assembly (1) has a stationary rocker arm shaft (10) on which at least two outer rocker arms (6, 7), that are in continuous contact with associated, differently contoured cams (4, 5), and a center rocker arm (8) with a lever arm extension (11) through which the gas exchange valve (2), in operative connection to one of the two outer rocker arms (6, 7), can be selectively actuated, are mounted for tilting movement. Actuatable locking pins (12, 13) are arranged on the outer rocker arms (6, 7) for sliding axially parallel to the rocker arm shaft (10), a locking pin receiver (14) is arranged on the center rocker arm (8) and positioning aids (15, 16, 17) are arranged on the outer and the center rocker arms (6, 7, 8), so that the center rocker arm (8) can be selectively force-locked to one of the two outer rocker arms (6, 7) or be deactivated.

Abstract: A variable valve drive for changing control timing of cam-actuated gas-exchange valves of an internal combustion engine is provided, with a tappet (6a, 6b, 6c), which, with convex cam engaging contour (5), engages a cam (4a, 4b, 4c) of a camshaft (3a, 3b, 3c) and which is guided so that it can move in the longitudinal direction in a rotatable tappet guide (7a, 7b, 7c), whose rotational angle (9) is adjustable for changing the control timing. In this way, the tappet guide (7a, 7b, 7c) can rotate about a rotational axis (8) parallel to a longitudinal axis (2) of the camshaft (3a, 3b, 3c).
