摘要： PROBLEM TO BE SOLVED: To make fluid flowing through a shaft part of a spool to flow easily and improve flow efficiency of the fluid. SOLUTION: A spool valve is provided with a stem portion 60f that defines a fluid passageway 56f formed by either (a) a single central support having a non-cylindrical curved surface shaped hydrodynamically, or (b) only a pair of sidewalls with, preferably, interior surfaces that are also shaped hydrodynamically. These stem passageways, which are designed to facilitate the flow of high-speed/high-pressure fluids controlled by the valve, are maintained in a predetermined orientation relative to the ports of the valve cylinders by a mechanism preferably including (a) a cam-following roller 66a supported in a tang 62a fixed to each spool and (b) a two-element cam that captures the roller 66a within two of the parallel sides of a cam-track groove formed on the respective interior surfaces of each cam element.

摘要： The size, weight, and cost of a full-traction differential are significantly reduced by the synergism of several interrelated design features of a cartridge-like gear complex: (1) Each combination gear has only a shallow journal hole in each end of an otherwise solid gear body, being supported on mating hubs fixed to mounting plates slipped into a one-piece differential housing. (2) The solid worm-wheel portion of the combination gears has a deeper hour-glass shape. (3) Mating worm/worm-wheel teeth have a broad "supra-enveloping" contact pattern on only the drive side of the mesh. (4) The side-gear worms have closed-end teeth. (5) Both diameter and axial length of the side-gear worms are reduced by a special cutting process. The efficiency of the differential is increased by a thrust plate supported in the mounting plates and positioned between inner ends of the side-gear worms.

摘要： A modular track suspension system is readily adapted for attachment to any presently manufactured full-size automotive vehicle (10) built with a load-carrying frame (12), being easily substituted for the vehicle's conventional wheeled undercarriage either during or following final assembly. The module uses a pair of endless rubber tracks (14, 15), one track under each respective side of the vehicle; and each track (14, 15) is supported over tandem units (17, 18) with, preferably, side-by-side dual-wheels (20, 21 and 22, 23) having rubber tires. The dual-wheels are each movable in a vertical plane, and each dual-wheel can move separately and independently of the similar independent movement of the other dual-wheel with which it is in tandem. Each dual-wheel is also resiliently biased in the direction of the terrain on which the vehicle is standing or moving.

摘要： Smaller and lighter hydraulic pump/motors are provided with pistons having body portions substantially as long as the axial length of the respective cylinders in which they reciprocate. A plurality of respective lubricating channels, formed circumferentially and radially transecting the walls of each cylinder, is each positioned to be closed at all times by the axial cylindrical body of each respective piston during its entire stroke. Each lubricating channel is interconnected, one to another, to form a single, continuous lubricating passageway entirely within the cylinder block and not connected by either fluid "input" or fluid "output" passageways, being replenished solely by blow-by entering from the valve end of each cylinder. A plurality of sealing members, each located near the open end of each cylinder, substantially eliminates blow-by from this lubricating passageway, thereby significantly increasing volumetric efficiency. The resulting improved lubrication, in combination with unique spring-biased holddown assemblies, permits use of variable-angle swash-plate arrangements that require neither dog-bones at the outer ends of the pistons nor conventional nutating-only wobblers.
摘要翻译：较小和较轻的液压泵/马达设置有活塞，其活塞的主体部分基本上与它们往复运动的各个气缸的轴向长度相同。沿圆周方向和径向截取每个气缸的壁的多个相应的润滑通道各自被定位成在其整个冲程期间通过每个相应活塞的轴向圆柱形主体被关闭。每个润滑通道彼此相互连接，以形成完全在气缸体内的单个连续的润滑通道，并且不通过流体“输入”或流体“输出”通道连接，仅通过从阀门每个气缸的末端。位于每个气缸的开口端附近的多个密封构件基本上消除了该润滑通道的窜漏，从而显着提高容积效率。所产生的改善的润滑与独特的弹簧偏压的压紧组件相结合，允许使用可变角度的斜盘布置，其不需要在活塞的外端处的狗骨，也不需要常规的只有章动的摆动器。

摘要： A transmission has only a single, minimal orbiter in which an input gear and an output gear, each being connected to separate input and output shafts, are interconnected through an orbiting cluster gear that meshes with only the input and output gears. The cluster gear is carried by a web that is itself rotated by a hydraulic control motor through a first clutch. When rotation of the web is prevented, rotation of the input gear produces rotation of the output gear at a predetermined reduction of the input drive, this gear reduction being continuously diminished proportional to the speed of rotation of the web in a first direction. When the vehicle reaches highway speeds, the control motor is disconnected and a second clutch is activated to connect a predetermined overdrive that is located between the engine drive and the transmission rather than being conventionally positioned between the transmission and the final output shaft.

摘要： A steer-drive interposes respective left and right orbital gear drives (20, 22) into the vehicle drivetrain between the engine/transmission (10, 12) and the respective propulsion axles associated with each side of the vehicle. The orbital drive units comprise only an input gear (54) and an output gear (58) interconnected by at least one orbiting cluster gear (60, 61) that is supported in a rotating housing and also meshes only with the input and output gears. The orbital units are designed so that (a) when rotation of the housing (64) is prevented, driving torque is transferred at speed ratios selected to be as close to 1:1 as is practical, and (b) when steering torque causes rotation of the housing, the steering torque is added simultaneously in equal and opposite directions to the orbital units, causing the drive on one side of the vehicle to slow down at the same rate. The steer-drive is appropriate for the drivetrains of tracked vehicles, boats and airplanes.
