A finger lever of a valve train of an internal combustion engine, said finger lever comprising two side walls that are connected to each other by a crossbeam that acts through an underside at one end on at least one gas exchange valve and is mounted at a further end through a concave cavity on a head of a support element, a clip through which the finger lever is fixed in position on said head for displacement in a direction of pivot being applied to said further end, wherein a central section of the clip made of flat material is supported at the further end on the underside of the crossbeam and comprises an opening under the cavity, the head of the support element being retained behind an edge of said opening, each side wall being surrounded on an outer surface by a tab-like extension that starts laterally from the central section and is snapped at an end onto one of an upper side or a support surface substantially parallel to the upper side, so that the end of the extension engages over more than at least one half of a width of the upper side or of the support surface.

Finger lever of a valve train of an internal combustion engine

Disclosed is a drag lever () comprising two side walls () which are connected together by a transversal bar () which is arranged on an end () of the lower side () thereof on an end () thereof on a head of a support element () by means of a dome-shaped cavity () on a head () of a support element (). A clamp () is applied to the end () thereof. The clamp fixes the drag lever () to the head such that it can be displaced in a pivoting direction thereof. The clamp () is made of thin-walled wire material and extends essentially in a transversal manner in relation to the longitudinal axis of the drag lever () and is arranged on the lower side () of the transversal bar () by means of a central section () which is formed by webs () which extended in a semi-circular manner in a part of the support element () which has a reduced diameter () and is located below said head (). The clamp () continues on each outer surface () of a corresponding side wall () by means of two parallel projections () and the ends of said projections are snapped on an upper side () of the respective side wall () or on a bearing surface which is essentially parallel to the upper side () such that at least more than half of the upper side () or the bearing surface is covered.

Drag lever of a valve mechanism in an internal combustion engine

A device for the simultaneous actuation of two gas exchange valves (10) of an internal combustion engine by a camshaft (11) rotatably supported in a camshaft bearing (15,16), said device comprising a bridge (3) which, with the interposition of hydraulic valve clearance compensation elements (7), is in contact with valve shaft ends (9) of the gas exchange valves (10), and a guide rail (2) on which the bridge (3) is guided for longitudinal displacement by a linear bearing (5), said guide rail (2) comprising a first oil duct (18) which opens into the linear bearing (5) and a second oil duct (22) implemented in the bridge (3), which connects the valve clearance compensation elements (7) to the linear bearing (5), and the oil passes phase-wise from the first oil duct (18) into the second oil duct (22), characterized in that a third oil duct (21) branches from the first oil duct (18) and opens into the camshaft bearing (15,16).

Oil supply for a valve actuation device

A device for the simultaneous actuation of two gas exchange valves (2) of an internal combustion engine comprising a bridge (6) guided movably along a guide rail (8) which, with the interposition of hydraulic valve clearance compensation elements (4), is connected with valve shaft ends (3) of the gas exchange valves (2), a camshaft (16) rotatably supported in the cylinder head (1) by at least one camshaft bearing (15), comprising a bearing block (23) and a bearing cap piece (14) detachably connected thereto and an engine element (12) supporting the guide rail (8) at an upper end thereof, characterized in that the engine element (12) is implemented in one piece with the bearing block (23) and/or the bearing cap piece (14).
