    摘要: A multiplexed hydraulic control system having a plurality of channels (70) and a common source (50) of modulated hydraulic fluid. The common source (50) is shared among the plurality of channels (70) by providing a plurality of selector valves (21a-d), one for each channel (70), with electrical solenoids (23) for the selector valves being individually controlled by a control means (100). In a normal operating mode, the selector valves (21a-d) are operated individually and the modulating means (50) is controlled to direct fluid to the selected channel (70) in accordance with the demands placed on movement of the actuator (72) in that channel (70). In a second slewing mode, multiple selector valves (21a-d) are energized at the same time and the modulator (50) is controlled to produce sufficient fluid flow to slew all of the actuators (72) in the selected channels (70) at a desired rate.

    摘要: A multiplexed hydraulic control system in which high force margins for the multiplexer are achieved by employing hydraulic oscillators as the multiplexer driving means. The multiplexer (20) is typically in the form of a hydraulic cylinder (25) having an input port (40) and a plurality of output ports (27,28,41-43), with an operator (26) in the cylinder (25) for individually connecting the input port (40) to the output ports (27,28,41-43). The hydraulic oscillator (30) is mechanically coupled to the multiplexer operator (26), and oscillation of the former causes oscillation of the latter to sequentially connect the input (40) to each of the outputs (27,28,41-43). Various means are taught for initiating reversal of the oscillator (30) and controlling the oscillation speed.
