Abstract

PURPOSE: To obtain required power steering performance, using that the back pressure generated in the discharge pipe of the power steering mechanism is changed by the oil temperature, compensating the change of pump control pressure due to oil temperature change.
CONSTITUTION: A power steering mechanism is used to carry out power steering supplying hydraulic oil supplied through the supply port 14 from the steering pump 13 into the power cylinder 12 by operating the servo-valve in the housing 11 by handle operation, a by-pass valve 17 to connect or shut both chambers of the cylinder 12 in accordance with vehicle speed is installed to the cylinder 12. In this case, the by-pass valve 17 has the first and the second spool valves 22, 27 the opening area of slit 30 opened to the connection hole 26 is constructed to icrease the area through that the valve 27 is moved upward to the valve 22, the back pressure according to oil temperature operates to the top surface of large diameter section of the second spool valve 27 through the conduit 33.
