Shift actuator valve having a pressure dead band
摘要:
A valve assembly having a pressure dead band includes a first valve or sleeve slidably disposed within a valve body. A second valve is partially slidably disposed within the first valve and partially slidably disposed in the valve body. A plurality of fluid passages communicate with the valve assembly and provide a first flow of hydraulic fluid and a second flow of hydraulic fluid. A lower threshold of the pressure dead band is defined by the pressure on the combination of the first area of the first valve and the first area of the second valve required to balance the resultant force developed on the second area of the second valve. An upper threshold of the pressure dead band is defined by the pressure on the first area of the second valve required to balance the resultant force developed on the second area of the second valve.
