    • A roller skate includes a fixing seat, a plurality of wheels, and a safety device mounted on the wheel. The safety device includes a safety member mounted on the fixing seat and urged on the wheel, so as to adjust a rotation speed of the wheel. Thus, the roller skate can be fixed on the ground without rotation by the safety device, so that the learner can stand on the roller skate without movement so as to practice his/her balance. In addition, the safety member is slightly loosened from the wheels, so that the wheels are rotated at a lower speed, thereby facilitating the learner practicing the skating skill.
    • 滚轮溜冰鞋包括固定座,多个车轮和安装在车轮上的安全装置。 安全装置包括安装在固定座上并被推压在车轮上的安全件,以便调节车轮的转速。 因此,溜冰鞋可以固定在地面上,而不会被安全装置旋转,从而学习者可以不用动作地站立在溜冰鞋上,从而实现平衡。 此外,安全构件从轮子稍微松开,使得轮子以较低的速度旋转,从而便于学习者实践滑冰技巧。

    • A control valve for a device to variably adjust control times of gas-exchange valves of an internal combustion engine. The control device has a valve housing and a control piston. The valve housing has an axial cavity with a dividing element arranged in the cavity that separates the cavity into two partial spaces and hydraulically seals the spaces from one another. The dividing element is produced separately from the valve housing and is positionally fixedly fastened in the cavity of the valve housing. The first partial space holds the control piston, and a supply connection is formed in the region of the first partial space. The second partial space has at least one first opening via which pressure medium can be supplied to the second partial space by a pressure medium pump, and at least one second opening by which the second partial space communicates with the supply connection.

    • A wrench includes a shank having a drive head, a handle slidably mounted on the shank, and a resistance member mounted between the shank and the handle to provide a resistance to damp movement of the handle. Thus, when a force is applied on the handle to rotate the shank about the drive head, the force produces an axial component force which drives the handle to move relative to the shank, so that the resistance member is compressed, and the handle is moved on the shank to a determined position. In addition, the shank is provided with an indication portion to indicate a safety parameter of motion of the handle during movement of the handle.
