Abstract: The invention relates to a piece of sports equipment which is subject to a shock-like load. In a piece of sports equipment in accordance with the invention, an elongated support element is present which is at least regionally inwardly hollow. It can, for example, be an at least almost complete baseball bat or also only a part region at which a handle of a piece of sports equipment is present. At least one hollow space in which metallic and/or ceramic hollow bodies are present is present in the support element. In the piece of sports equipment, the support element can form the outer skin or at least a part thereof.

Abstract: An electromagnetically actuatable valve is proposed, which serves as a fuel injection valve for fuel injection systems in internal combustion engines. The valve includes a valve housing of ferromagnetic material, at least one magnetic coil mounted on a core of ferromagnetic material, and an armature arranged to actuate a valve closing element which cooperates with a valve seat. The armature protrudes beyond a ferromagnetic annular disk supported on a support shoulder of the valve housing and a stop disk of hard, nonmagnetic material is arranged in the annular groove of the annular disk such that when the armature is resting on the stop disk, a remnant air gap is formed in the axial direction between the annular disk and the armature.
