Abstract
PURPOSE: To exclude the back pressure that acts on a power cylinder chamber when a power steering valve operating valve is in neutral, by providing an auxiliary valve that can be operated in response to the pressure difference between a pair of power cylinder chambers for performing the power shift during power steering.
CONSTITUTION: The power steering apparatus has a power piston, which is slidable in a power cylinder (not shown), on a rack 4 that is guided by a rack guide 2 provided to one end of a valve box 1. Rack teeth 4a of the rack 4 are meched with a pinion 11a of a pinion shaft 11, and the shaft 11 is connected through a stub shaft 17 and others with a steering shaft. The auxiliary valve is provided which includes a spool 52 slidably inserted into a through hole 51 of the valve box 1 and can drain the back pressure acting into the power cylinder chambers difined by the power piston of the power cylinder when the inner and outer sleeves 24, 25 acting as operating valves are in neutral.
