    摘要： A hydraulic servo regulating device of an automatic transmission, which according to the present invention applies enough line pressure quickly to a hydraulic servo and obviates a delay when the line pressure is to be drained, is disposed in an oil path between a shift valve and an accumulator. The device employs regulator valve which has an application port connected to a shift valve, a regulating port in selective communication with the application port, a first feedback port through which feedback pressure is applied to one end of a spool, a second feedback port through which feedback pressure is applied to the other end of the spool, a spring and a drain port connected to the regulating port. Furthermore, the regulating port communicates with a hydraulic servo through a first oil path, and an accumulator chamber through a second oil path having an orifice and branched off from the first oil path. And, the regulator valve also communicates with the first feedback port through a third oil path having an orifice and branched off from the first oil path, and the second feedback port through an oil path branched off from the second oil path. A fourth oil path connects the first oil path and is branched off from the second oil path, and a check valve which controls oil flow from the second oil path to the first oil path is disposed in the fourth oil path.
