The invention proposes a finger lever (1) of a valve train of an internal combustion engine, said finger lever (1) being switchable to different valve lifts for at least one gas exchange valve and comprising an outer lever (2) having two arms (3a, 3b) between which an inner lever (4) is arranged for pivoting relative to the outer lever (2), which outer and inner levers (2, 4) can be coupled to each other by a coupling means (15), the outer lever (2) comprising on one closed end (5), a support (5a) for a gas exchange valve and the finger lever (1) comprising on an opposite end (6), a complementary surface (7, 30) for a support element, the inner lever (4) having a fulcrum (10) in a region of the opposite end (6), and at least this inner lever (4) comprising a contact surface (11) for a cam. In the finger lever (1) of the invention, the outer lever (2) has a substantially open fork-like configuration, the contact surface (11) for the cam on the inner lever (4) is configured as a rotatable roller (12) and the coupling means (15) comprises at least one slide (16, 19, 22) that extends crosswise to a longitudinal direction of the finger lever (1), an axial line of the at least one slide (16, 19, 22) coincides with an axial line of the roller (12), and the fulcrum (10) of the inner lever (4) is situated at least approximately at a same point on a length of the finger lever (1) as a fulcrum of the outer lever (2) in a region of the complementary surface (7) of the finger lever (1). The switchable finger lever (1) of the invention has only a small design space requirement and a coupling mechanism of a relatively simple structure.

The invention proposes a switchable tappet (1) for the direct transmission of a cam lift to a tappet push rod. A coiled compression spring (15), used as a lost motion spring, for loading the inner element (4) is shifted axially out of a housing (2). For this purpose, the inner element (4) comprises an extension (15a) that projects out of the housing (2) and is surrounded by the coiled compression spring (15). This measure contributes to minimizing the total mass of the switchable tappet (1) because the overall length of the housing (2) is shortened.

A rocker arm (6) that can be uncoupled from the cam lift, the axle (11) of this rocker arm (6) is guided for longitudinal movement in a slot (12) of a pedestal (13), and the rocker arm (6) can be coupled to the pedestal (13) by locking elements (20, 21, 22) or it can be uncoupled from the pedestal (13) by these locking elements (20, 21, 22) for achieving a zero lift of an associated gas exchange valve (9).
摘要:
A finger lever (1) is configured for the simultaneous loading of three identically operating gas exchange valves. To simplify the manufacture of a hydraulic medium supply of its hydraulic clearance compensation elements (4) resting on valve stem ends and to prevent unnecessary losses of hydraulic medium, the invention proposes the arrangement of only one central passage (12) in the finger lever (1) for supplying all the clearance compensation elements (4). This passage (12) extends near a central transverse plane of the finger lever (1) and opens into a cross-passage (10) in the form of a through-bore to the individual clearance compensation elements (4).
摘要:
A sleeve-like element (14) is arranged inside a hydraulic support element to secure against drainage. In axial direction, the sleeve-like inner element (14) bears a shoulder (13) of a piston (4), formed by a rolled-in step (12). In this manner, the inner element (14) can be secured while the piston (4) maintains a uniform wall thickness.
