Abstract
PURPOSE: To obtain the optimum steering force by adequately satisfying demanded flow rate characteristic all the time, by electrically detecting car speed accurately proportional to steering resistance, and by controlling the feed quantity of pressure fluid on the basis of the detected signals.
CONSTITUTION: This power steering device is arranged by providing with a flow rate control portion 1 put between a flow path for introducing oil discharged from an oil pressure pump P, which is driven in synchronous with the revolution of an engine, to a power steering portion 2. The flow rate control portion 1 is equipped with a variable orifice O produced by inserting a measuring rod 13 into a through hole 12 in a forwarding and backing-free shape, a control spool 5, which responds to the before and behind differential pressure of the orifice and makes one portion of discharged oil bypass, a car speed detecting portion 25 for electrically detecting car speed, a stage control circuit 32 for varying output current by stages in response to the detected signals, and a solenoid 34 for controlling the location of said measuring rod 13 by the phased output current.
