PURPOSE:To reduce the cost and weight of the titled device by using a single oil pump for supplying oil pressures to an automatic speed change gear and a power steering gear. CONSTITUTION:The oil pump 10 driven by an engine supplies the oil sucked in from an oil pan to a port 16 of a flow control valve 14 which is generally used for the power steering gear. A port 30 of the valve 14 is communicated with a port of a change-over valve 40 for the power steering gear, while a port 32 of the valve 14 is provided in an oil pressure circuit for the automatic speed change gear and is communicated with a port of a regulating valve 96 which regulates the line pressure in the circuit. The regulated line pressure is fed to various pressure-regulating valves and friction engaging device of the automatic speed change gear through an oil passage 100. |
