FLUID FEED CONTROL DEVICE

摘要

PURPOSE: To control the mechanical distribution of the pressure oil to a power steering device and the pressure oil to an alignment control device in a highly reliable manner with simple constitution at a low cost. CONSTITUTION: Preferential feeding of the pressure oil from a main flow passage 61 to a P/S valve 24 of a power steering device and feeding of the excessive pressure oil from a second flow passage 67 to an accumulator 27 of an alignment device are realized by the movement of an accumulation spool valve 76 to be opened/closed by the accumulation force of the accumulator 27 through a check valve 69 to be opened/closed by the hydraulic force and an accumulation rod 80. The pressure oil is mechanically distributed to the power steering device of different control system and the control system of the alignment control device, and the distribution of the pressure oil to the power steering device and to the alignment control device is controlled with high reliability at a low cost with simple structure without using the electronic control using electric valves or sensors.
