摘要： A throttling valve assembly has an outer housing that is sealed. An actuator is connected to a pressure balanced shaft that extends into the housing to operate a plurality of linkages that can rotate blades in tandem. With the surrounding housing sealed, the shaft penetrations of the blade support shafts no longer need seals or a purge system to supply process gas during times of reduced pressure in situations with the blades nearly closed. A pressure equalization system has balance passages internal to the housing to allow flow from higher pressure zones to lower pressure zone of the process gas so as to avoid creation of a condition that can draw air into any zones of reduced pressure in the housing.

摘要： A variable displacement compressor comprises an opening-degree adjustment valve which is disposed in a flow passage between a suction port and a suction hole communicating with a cylinder bore and variably controls the opening area of the flow passage. The variable displacement compressor is characterized in that the resistance against the movement of the valve body of the opening-degree adjustment valve in the direction of increasing the opening area of the flow passage is made to be greater than the resistance against the movement thereof in the direction of decreasing the opening area. The liquid compression at the starting of the compressor is prevented from occurring, whereby the durability and the reliability of the device can be improved and the device can exhibit excellent displacement control responsiveness.
摘要翻译：可变排量压缩机包括开度调节阀，其设置在吸入口和与缸孔连通的吸入孔之间的流动通道中，并可变地控制流路的开口面积。可变排量压缩机的特征在于，使开度调节阀的阀体沿着增加流路的开口面积的方向的运动的阻力大于在其中的阻力减少开放面积的方向。在压缩机起动时的液体压缩发生，能够提高装置的耐久性和可靠性，能够显示优异的位移控制响应性。

摘要： A hydraulic machine in which the volume of working fluid displaced by each cylinder is selectable on each cycle of working chamber volume by active control of one or more electronic valves has a controller configured to select specified groups of cylinders to repetitively carry out active cycles until a change in selection is made. The groups are selected to reduce torque ripple and/or bearing side load. The cam profile may be varied to further reduce torque ripple.

摘要： A compressor system for a compressed-air supply arrangement includes an adjustable throttle device arranged in the suction line of the compressor. The throttle device is adjustable between a fully open load position and an idle position with a predefined narrowed throttle cross section. The idle power of the compressor is reduced as a result of the reduction of the pressure level downstream of the throttle device without additional lines, filters or the like.
