Abstract: A fluid drive transmission in which a moving fluid is used to connect the drive and driven members together. The drive and driven members both comprise rollers having longitudinally mounted, spiral shaped vanes extending about their periphery. The rollers are mounted in end to end spaced relationship in a common housing with a greater radial spacing provided between the periphery of the driving member and the housing than between the periphery of the driven member and housing. The system further includes a combined apparatus for supplemental braking which includes a valve connected in a closed hydraulic path between the ends of the housing. The valve is effective to retard the pressurized flow of the fluid upon application of the brakes thus assisting in slowing down the speed of operation of the transmission and retarding the drive output.

Abstract translation: 流体驱动传动装置，其中使用移动流体将驱动部件和被驱动部件连接在一起。 驱动和从动构件都包括具有沿其周边延伸的纵向安装的螺旋形叶片的辊。 辊子在公共壳体中以端对端间隔开的关系安装，在驱动构件的周边与壳体之间设置有较大的径向间隔，而不是在从动构件的周边与壳体之间。 该系统还包括用于补充制动的组合装置，其包括连接在壳体的端部之间的封闭的液压路径中的阀。 该阀在施加制动器时有效地阻止流体的加压流动，从而有助于减慢变速器的操作速度并延迟驱动输出。
