摘要： A dual range infinitely variable transmission utilizes a continuously variable speed mechanism in conjunction with a fixed ratio speed mechanism to provide two power paths from the input to the rotatable output. A jaw clutch is utilized to switch between the high range and low range of the transmission. A reaction type clutch is utilized to provide a positive neutral for the transmission.

摘要： A continuously variable transmission with synchronous shift includes an input, an output, a fixed-ratio drive mechanism and a variator in driven relationship with the input, a planetary gear assembly having a sun gear, a ring gear, a carrier, and a plurality of planet gears, a first clutch for engaging the variator selectively with the sun and ring gears, a second clutch for engaging the mechanism selectively with the carrier and sun gear and for disengaging the mechanism therefrom, and a third clutch for engaging the ring gear and carrier selectively with the output. This relationship provides the transmission with a plurality of drive ranges and the capability of shifting from any range to any other range at a synchronous shift point established when the variator ratio is equal to the ratio of the mechanism.

摘要： A capacity control circuit for a fluid displacement apparatus, especially for a rotary vane compressor, which circuit controls the volume of fluid displaced or transmitted through such apparatus. The present invention provides a means to retain the vanes within the rotor guide slits with a fluid pressure differential to modulate the volume throughput of such rotary vane compressor or apparatus. This vane control is provided by controlling the suction or input pressure to such apparatus through a fluid control valve.

摘要： A controlled, variable displacement swash plate compressor is provided with means for controlling the capacity pivoting the swash plate about the drive shaft axis to vary the effective pumping capacity. The position of the swash plate with respect to the drive shaft axis is a function of the pressure maintained inside the crankcase, said position being a result of the various forces acting on the pistons, including the underside of the pistons where crankcase pressure is applied. A cam surface is provided to maintain a fixed top dead center position at all displacements, as well as an improved universal joint mechanism to anchor the swash plate against rotation.

摘要： A controllable, variable displacement swash plate compressor including a centrally pivoted swash plate on a rotating shaft. Control means are provided to increase or decrease the angle of inclination of the swash plate in response to changes in suction pressure. The delivery from the compressor may be reduced rapidly from the maximum as the angle of inclination is reduced, due partly to the reduction in stroke, but mainly to the increased clearance volume, i.e. the volume above the piston in the cylinder, and the consequent re-expansion of the trapped gas in the clearance volume. This achieves a more efficient method of reducing compressor output to match system requirements than suction gas throttling, a commonly used technique in automotive air conditioning applications. In addition, it does not require a clutch since it may be run for prolonged periods at or near zero capacity (no-stroke condition) when cooling is not required.
摘要翻译：一种可控的可变排量斜盘压缩机，其包括在旋转轴上的中心枢转的斜盘。提供控制装置以响应于吸入压力的变化来增加或减小斜板的倾斜角度。压缩机的输送可能会随着倾斜角度的减小而从最大程度上迅速减小，这部分是由于行程减少，主要是由于增加的间隙体积，即气缸中活塞上方的体积，在间隙容积中膨胀被捕获的气体。这实现了比吸入气体节流（汽车空调应用中常用的技术）更有效的降低压缩机输出以匹配系统要求的方法。此外，它不需要离合器，因为当不需要冷却时，它可以运行长时间处于或接近零容量（无行程状态）。

摘要： A controlled, variable displacement wobble plate compressor is provided with means for controlling the capacity by sliding the wobble plate to and fro along the drive shaft axis to vary the effective pumping capacity. The position of the wobble plate along the drive shaft axis is a function of the pressure maintained inside the crankcase, said position being a result of the various forces acting on the pistons, including the underside of the pistons where crankcase pressure is applied.
