Abstract

PURPOSE:To obtain a speed sensitive type power steering with hydraulic equipment only by making pressure to be guided to a reaction chamber of a reaction pressure control valve lower in proportion as making differential pressure before and behind a throttle installed at the downstream side of a flow control valve smaller. CONSTITUTION:A flow control valve VF is connected to the discharge side of a pump P being interlocked with an engine. And an outflow port of this flow control valve VF is interconnected to a port 10 of a steering control valve 3 via a passage 51, and a throttle 52 is formed in this passage 51. Likewise, a reaction pressure control valve VO is connected to the passage 51, and in the valve body 53, there are provided with a pressure port 58 connected to the passage 51 at the downstream side of the throttle 52, an inflow-outflow port 59 connected to respective reaction chamber 7, 8 of the steering control valve 3 and a tank port 60 interconnected to a tank T. At this time, in proportion as making differential pressure before and behind the throttle 52 smaller, opening of a flow passage interconnecting the inflow-outflow port 59 to the tank port 60 is made larger. Each pressure in these reaction chambers 7, 8 is thereby lowered.
