Abstract

PURPOSE: A shock preventive device, whereby an oil pressure to be fed to the hydraulic servo system has been made adequately adjustable for preventing a shock at the operation of speed change.
CONSTITUTION: A hydraulic oil pressure control circuit, for automatically or manually operating a pressure regulating action when a speed is shifted as well as for selectively actuating a clutch and brake 12, 19, 24 to 27 of the automatic transmission, comprises an oil reservoir 100, oil pump 101, pressure regulator valve 200, manual valve 210, each shift valve 220, 230, 240, 250 and accumulator 360. In this case, a shock preventive valve 260 is provided having an operating oil chamber 263, pressure regulated in a prescribed pattern by a pressure regulating solenoid valve 300 on-off operated at a prescribed period, and a first and second pressure regulating chamber 264, 265, for regulating an oil pressure at the time of forward and backward motion respectively. And when in a motion made forward and backward, the respective pressure regulating chamber 264, 265 is made an operation to regulate the oil pressure fed to the hydraulic servo at a work of shifting.
