    • A sacral support assembly for use with a seat is provided. The seat includes a seat frame. An adjustable sacral support assembly is connected to the seat frame. The sacral support assembly includes a sacral support member adapted to support the sacrum of a seated user. A method is also provided for delivering adjustable, stabilizing support to a user's sacrum and sacral-pelvic anatomy to reduce fatigue, increase comfort, stability and posture for a user, and a system for adjusting and controlling the load distribution from the sacral anatomy to the anatomical structures adjacent to a user's sacrum, for example, the pelvis and lumbar regions.
    • 提供了一种用于座椅的骶骨支撑组件。 座椅包括座椅框架。 可调节的骶骨支撑组件连接到座椅框架。 骶骨支撑组件包括适于支撑就座者的骶骨的骶骨支撑构件。 还提供了一种方法,用于将可调节的稳定支撑件提供给使用者的骶骨和骶骨骨盆解剖结构,以减少疲劳,增加使用者的舒适性,稳定性和姿势,以及用于调整和控制从骶骨解剖结构到 与用户骶骨相邻的解剖结构,例如骨盆和腰部区域。

    • A low noise gear set for use generally and preferably with a power plant having an engine driving a pump connected to a low pressure fluid source, generating high pressure fluid at an output. The idle gear meshes with the drive gear along two points of the profile of the corresponding gears. The first point being the root of one gear tooth meshing with the tip of the opposite gear tooth creating an initial first contact point and a subsequent second point along the profile when the teeth are disengaging at the first point and engaging at the second point, forming a sealed area, allowing the fluid to hydrostatically escape between the points.
    • 一种低噪音齿轮组,通常用于优选地具有发动机,发动机驱动连接到低压流体源的泵,在输出端产生高压流体。 空转齿轮沿着相应齿轮轮廓的两个点与驱动齿轮啮合。 第一点是与相对齿轮齿的尖端啮合的一个齿轮齿的根部,当牙齿在第一点处脱离并接合在第二点时,形成初始的第一接触点和随后的第二点,形成 密封区域,允许流体在点之间流体静力地逸出。

    • A variable capacity pump/motor has a meshing internal and external gear set disposed between an upper mandrel and a lower mandrel, each including a flange extending towards the gears to divide a pump/motor chamber into suction and discharge chambers. The outer gear is fixed and the internal gear is axially moveable with respect thereto. The inner gear and the upper mandrel move in response to changing pressures in the casing, allowing the motor to vary displacement and the pump to vary its output based on supplied fluid pressure or based on the speed of the prime mover. An external configuration includes a pair of meshing gears mounted on separate shafts in a casing. One gear is fixed and the other is axially moveable with respect thereto and moves in response to changing pressures in the casing. Each of the gears is sealed by a seal/bushing on a free end thereof.
    • 可变容积泵/马达具有设置在上心轴和下心轴之间的啮合内齿轮组和外齿轮组,每个齿轮组包括朝向齿轮延伸的凸缘,以将泵/马达室分成吸入和排出腔。 外齿轮是固定的,并且内齿轮相对于其可轴向移动。 内齿轮和上心轴响应于壳体中变化的压力而移动,允许马达改变位移,并且泵基于所提供的流体压力或基于原动机的速度来改变其输出。 外部构造包括一对啮合齿轮,其安装在壳体中的分离的轴上。 一个齿轮是固定的,另一个齿轮相对于其轴向移动并响应于壳体中的变化的压力移动。 每个齿轮在其自由端上由密封件/衬套密封。
