Abstract

PURPOSE: To prevent steered wheels from being deflected in one direction when back pressure becomes high, by shutting off a liquid supply passage and a passage, which is connected to a liquid chamber of larger liquid pressure reception area in a power cylinder, at one valve groove in the neutral position of the change-over control valve of a power steering gear provided with the power cylinder.
CONSTITUTION: When a vehicle is moving straight or the spool 28 of a change-over control valve 31 is in neutral position, a groove 26 is disconnected from another groove 24 but connected to still another groove 23 and still another groove 27 is connected to grooves 24, 25. For that reason, pressurized liquid is returned to a liquid reservoir 66 through the grooves 27, 25, a passage 4b and an orifice 60. The pressure at the upstream side of the orifice 60 or in the groove 27 is higher than that at the downstream side or in a passage 4 and enters into a liquid chamber 20 through a passage 13 to act to the smaller liquid pressure reception side of a piston 19. When a steering wheel is turned to the right, a shaft 11 is moved rightwards by at a stroke δ and the spool 28 is moved rightwards so that a liquid pressure circuit which produces motive power to deflect steered wheels rightwards is formed for a power cylinder 17.
