    • A linear actuator for a rotating shaft assembly includes a cylinder and a piston arranged within a cavity defined by the cylinder. Faces of the piston delimit first and second chambers within the cavity. A rotatable shaft fixed to the piston defines a first main passage in fluid communication with the first chamber and a second main passage in fluid communication with the second chamber. A pressure delivery body rotatably fixed to the rotatable shaft defines a first delivery passage in fluid communication with the first main passage and a second delivery passage in fluid communication with the second main passage. A passage isolation system selectively isolates fluid communication between the first delivery passage and the first main passage and fluid communication between the second delivery passage and the second main passage. A pressure limiting system selectively blocks fluid communication through the first and second main passages.
    • 用于旋转轴组件的线性致动器包括设置在由气缸限定的空腔内的气缸和活塞。 活塞的面限定了空腔内的第一和第二腔室。 固定到活塞的可旋转轴限定与第一室流体连通的第一主通道和与第二室流体连通的第二主通道。 可旋转地固定到可旋转轴的压力传送体限定了与第一主通道流体连通的第一输送通道和与第二主通道流体连通的第二输送通道。 通道隔离系统选择性地隔离第一输送通道和第一主通道之间的流体连通以及第二输送通道和第二主通道之间的流体连通。 压力限制系统选择性地阻止通过第一和第二主通道的流体连通。

    • A toy vehicle is provided for use in a toy vehicle game including an endless track defining at least two parallely extending vehicle lanes in which two or more toy vehicles are adapted to be operated. The toy vehicles each include a reversible rotary drive motor and a transmission operatively engaged between the motor and two drive wheels for rotating one or the other of the drive wheels in response to the direction of rotation of the drive motor, thereby biasing the car against one or the other of the side walls of the track to guide the vehicle along its path of travel in one or the other of the lanes. The track includes electrical contact strips which supply power to the drive motor of the vehicles through current collectors mounted thereon. A control system permits the operators to separately and independently control current to the contact strips and also to selectively reverse the polarity of the current so that the operators can vary the speed of their associated vehicles and cause the vehicles to move from one lane to the other. In one form of the invention an additional toy vehicle operated as a drone car at constant speed is provided presenting an obstacle along the track which the players must pass by properly controlling their respective toy vehicles.
    • 提供一种用于玩具车游戏中的玩具车,其包括限定至少两个平行延伸的车道的环形轨道,其中两个或更多个玩具车辆适于操作。 玩具车各自包括可逆旋转驱动电动机和可操作地接合在电动机和两个驱动轮之间的变速器,用于响应于驱动电动机的旋转方向旋转一个或另一个驱动轮,从而将轿厢抵抗一个 或轨道的另一侧壁,以引导车辆沿其一条或另一条车道中的行进路线。 轨道包括通过安装在其上的集流器向车辆的驱动马达供电的电接触条。 控制系统允许操作者单独且独立地控制到接触片的电流,并且还选择性地逆转电流的极性,使得操作者可以改变其相关联的车辆的速度并使车辆从一个车道移动到另一个车道 。 在本发明的一种形式中,提供以恒定速度作为无人驾驶车操作的附加玩具车辆,其通过适当地控制其各自的玩具车辆而沿轨道提供障碍物,玩家必须通过该障碍物。
