Abstract: The invention relates to a cylinder head (1) with at least one recess (23) for arranging at least one gas valve (20) and at least one spark plug (15). The spark plug (15) reaches into a pre-chamber (17) and is arranged along a spark plug rotational axis (16), and the gas valve (20) is arranged along a gas valve rotational axis (19), wherein the gas valve rotational axis (19) is inclined relative to the spark plug rotational axis (16), and the distance (A) between the gas valve rotational axis (19) and the spark plug rotational axis (16) decreases as the distance to the pre-chamber (17) increases in a direction facing away from the combustion chamber (2). The aim of the invention is to provide an improved cylinder head (1) which allows an improved assembly and requires less installation space. According to the invention, this is achieved by the aforementioned cylinder head (1) in that the recess (23) for the spark plug (15) and the gas valve (20) has a surface (0) which is formed by a primary molding process, preferably a casting process, and is post-processed particularly preferably without machining.

Abstract: Various aspects of the present disclosure are directed to a cylinder head for an internal combustion engine. In one example embodiment, the cylinder head includes at least one spark plug having at least one earth electrode, a precombustion chamber accommodating the at least one spark plug, and a fuel channel which leads into the precombustion chamber. The fuel channel having a flow axis at an outlet that is oriented in the direction of the at least one earth electrode. An axis of rotation of the at least one spark plug has an offset with respect to the flow axis between 0 and 15% of the greatest precombustion chamber diameter.

Abstract: The present invention relates to a coupling device for a valve-actuating device for actuating at least one valve of a reciprocating machine having variable valve lift, in particular for a valve-actuating device of a reciprocating internal combustion engine, to a valve-actuating device and to a reciprocating machine, the coupling device comprising a first coupling element, a second coupling element and a blocking means. The first coupling element and the second coupling element can be displaced relative to one another at least within defined boundaries along a first axis, it being possible for the blocking means to block the relative displacement of the two coupling elements with respect to one another along the first axis at least in a first direction. The blocking means comprises a blocking element, which can be rotated about the first axis in the circumferential direction at least in a defined region, the relative displacement of the two coupling elements along the first axis being blocked at least in the first direction if the blocking element is in a blocking position.
