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.

摘要： 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 in the respective interior surfaces of each cam element.
