摘要： 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.
摘要翻译：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。

摘要： A solenoid valve and manifold assembly for installation on an engine and connecting with hydraulic circuits in the engine for de-actuating the combustion chamber valves of selected cylinders of the engine. A manifold deck is formed with the valving channels and ports therein for connecting to the hydraulic circuits. A gasket is formed with solenoid valve mounting bosses and valving passages as a unitary member and is retained on the manifold deck by a retaining plate preferably stamped from sheet stock with clearance holes received over the valve mounting bosses and secured to the manifold deck over the gasket for sealing the gasket thereon. The valves are inserted in the bosses and retained by a preferably stamped bracket and the bracket, retaining plate and gasket secured to the manifold deck by common fasteners. A common electrical lead frame is received over the valve terminals for making electrical connection to the valves. The assembly of valves and the manifold deck may then be attached to the engine as a unit.

摘要： 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.

摘要： 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.
摘要翻译：扳手包括具有驱动头的柄，可滑动地安装在柄上的手柄，以及安装在柄和手柄之间以阻止手柄的潮湿运动的阻力构件。因此，当将力施加在手柄上以围绕驱动头旋转柄时，该力产生驱动手柄相对于柄移动的轴向分力，使得阻力构件被压缩，并且手柄移动在柄上确定的位置。此外，柄设置有指示部分，以在手柄移动期间指示手柄的运动的安全参数。

摘要： A wrench includes a drive head, a drive member, a plurality of locking teeth mounted on either one of the inner wall of the drive head and the drive member, and two locking devices located beside the drive member. An urging block is located between the two locking devices for pressing one of the two locking devices to engage with the drive member. Each of the locking devices includes two driving blocks each formed with a locking end engageable with the locking teeth to drive the drive member. The locking ends of the two driving blocks are respectively engaged with the locking teeth at different time. Thus, the locking device has a smaller driving angle for driving the drive member.
