摘要： A hydraulic control circuit (1) is provided with a pressure adjusting valve (10) for regulating a discharge pressure of an oil pump (OP), a pressure regulating valve (20) for adjusting a pilot pressure (P3) of the pressure adjusting valve (10) to a torque converter pressure (P4), and an oil passage (53) that connects an output port (15) of the pressure adjusting valve (10) and an oil passage (59), the pressure regulating valve (20) having an input port (24) connected to the oil passage (53) through an oil passage (54), a drive pressure port (22) connected to the oil passage (53) through an oil passage (55), a spool (26) axially displaced according to a drive pressure (P5) inputted into the drive pressure port (22), and an output port (25), and the pressure regulating valve being configured to regulate the torque converter pressure (P4) by an axial displacement of the spool (26). A throttle (30) is provided between the connection section (531) of the oil passage (53) and the oil passage (55) and the connection section (541) of the oil passage (53) and the oil passage (54), for adjusting the torque converter pressure (P4) to an appropriate pressure.
