Abstract: The invention relates to a piston internal combustion engine comprising upper camshafts (2, 3) for actuating gas exchange valves, whereby respectively adjacent lying bearings of the induction-side camshaft (2) and the exhaust-side camshaft (3) are provided with a covering element (5) scaling both bearings. The inventive engine is also provided with direct fuel injection by means of a respective injector device (7) which has a nozzle part and which is associated with a cylinder (I, II, III, IV). The nozzle part is sealingly inserted into an opening in the cylinder head (1) and a cross brace (8) is fixed to the cylinder head (1) in a deflection-resistant manner, overlapping with at least one injector device (7). The cross brace is connected to tightening elements (11) enabling the injector devices (7) to be sealingly tightened in relation to the cross brace (8). The cross brace (8) is connected to least two neighbouring bearing-covering elements (5).

Abstract: An electromagnetic actuator includes an electromagnet composed of a yoke provided with a pole face and a solenoid which is carried by the yoke and which is energizable with electric current for generating electromagnetic forces. An armature coupled to a setting member is movable into engagement with and away from the pole face of the yoke. A resetting spring is connected to the armature for opposing movements of the armature toward the pole face. The yoke and/or the armature is at least in part elastically deformable toward the armature and the yoke, respectively.
