摘要： The invention relates to a valve drive (1a, 1b) which is used to actuate a gas exchange valve (5) in a cylinder head (2) of an internal combustion engine having a mechanical valve play position, in addition to a method for the mounting thereof. A cam follower (10), which is mounted on a support element (8) which has a rigid height (characteristic YP) and which is stationary in the cylinder head (2), is arranged in a dimensionally paired manner between a cam (3) of a cam shaft (4) and a gas exchange valve (5) in order to adjust the valve play (21) in relation to the cam (3) and/or the gas exchange valve (5) with the support element (8). The invention is characterised in that a component (6), which is coupled to the outside of the cylinder head (2) having a determined total constructional size, and which can be mounted in the cylinder head (2), comprises the cam follower (10) and the support element (8).

摘要： Disclosed is a drag lever (1) comprising two side walls (2, 3) which are connected together by a transversal bar (4) which is arranged on an end (6) of the lower side (5) thereof on an end (6) thereof on a head of a support element (9) by means of a dome-shaped cavity (7) on a head (8) of a support element (9). A clamp (10) is applied to the end (6) thereof. The clamp fixes the drag lever (1) to the head such that it can be displaced in a pivoting direction thereof. The clamp (10) is made of thin-walled wire material and extends essentially in a transversal manner in relation to the longitudinal axis of the drag lever (1) and is arranged on the lower side (5) of the transversal bar (4) by means of a central section (11) which is formed by webs (12, 13) which extend in a semi-circular manner in a part of the support element (9) which has a reduced diameter (14) and is located below said head (8). The clamp (10) continues on each outer surface (15, 16) of a corresponding side wall (2, 3) by means of two parallel projections (17a, 17b; 18a, 18b) and the ends of said projections are snapped on an upper side (19, 20) of the respective side wall (2, 3) or on a bearing surface which is essentially parallel to the upper side (2, 3) such that at least more than half of the upper side (19, 20) or the bearing surface is covered.

摘要： The invention relates to a cam follower (1) for a valve gear in an internal combustion engine, comprising two lateral walls (2, 3), connected to each other by means of a crossbar (4). Said crossbar (4) is mounted on a head (10) of a support element (11) by means of a concave moulding (9) at the end (8) of the underside (5) thereof. A clip (12) is applied to the end (8), by means of which the cam follower (1) is fixed on the head (10) such as to move in the pivoting direction thereof. A central section (13) of the clip (12), made from a flat material, is supported on the underside (5) of the crossbar at the end (8) and has a recess (14) beneath the moulding (9), behind the edge (15) of which the head (10) of the support element (11) is fixed. Each lateral wall (2, 3) is enclosed around the outer surfaces (18, 19) thereof by a tang-like projection (16, 17), extending laterally from the central section (13) and clipped to an upper surface (22, 23) or a support surface (24) essentially parallel to the upper surface at the end (20, 21) thereof, such that the end (20, 21) of the projection (16, 17) grips over at least more than a half of a width of the upper side (22, 23) or support surface (24).
