摘要： An exemplary hydraulic system (10) includes a plurality of digital valves (40, 70, 86, 100) each valve fluidly connectable to a corresponding hydraulic load (26,28,30). The digitals valves are operable to fluidly connect the corresponding hydraulic load to a pressure source (12). The hydraulic system further includes a digital controller (114) operably connected to the plurality of digital valves. The digital controller is configured to assign a priority level so that it is associated with each of a plurality of hydraulic loads, and to formulate a pulse width modulated control signal based on the assigned priority levels. The digital controller transmits the control signal to the plurality of digital valves for controlling the operation of the valves.

摘要： A valve is provided including a first valve member (64) and a second valve member (66). The first valve member (64) includes a first step and a first orifice (82) adjacent the first step. The second valve member (66) includes a second step and a second orifice (80) adjacent the second step. The second valve member (66) is movable relative to the first valve member (64) between an open position, in which the first orifice is fluidly connected the second orifice, and a closed position, in which the first orifice is substantially fluidly disconnected from the second orifice. The first and second steps are fluidly connected to the second orifice and substantially fluidly disconnected from the first orifice when the second valve member (66) is in the closed position, and the first and second steps are fluidly connected to the first and second orifices when the second valve member (66) is in the open position.
